Sound Ordnance B-8PTD powered sub

This compact sub delivers strong bass without taking up much space.

Big bass from this tough little sub

A 125-watt RMS Class D amplifier powers the sub and lives on a compact circuit board mounted inside the enclosure. The sub's stiff 8" aluminum cone holds its shape even when playing hard, helping to keep the lowest notes clean, and ensuring a long life for the sub. You can adjust the low-pass filter, variable phase control, and bass boost to get the B-8PTD sounding perfect in your vehicle. Preamp- and speaker-level inputs allow convenient connection to just about any system, even a factory stereo.

Sound Ordnance B-8PTD powered subwoofer

The molded ABS enclosure houses a 125-watt amp and a tough little 8" sub.

Good design helps

The B-8PTD's tough outer casing of molded ABS plastic serves as the sub's sealed enclosure and can withstand some pretty extreme internal pressure changes with no reverberating or buzzing. Sound Ordnance conveniently located the neat, clean, easy-to-understand controls on one side, opposite all the connections, so you won't get tangled in wires as you tune your bass. The control knobs and switches aren't recessed, so you can make adjustments by hand, without the need for a tiny screwdriver.

This definitely adds the punch that was needed... [ JOEY  Apr 16, 2017 ]
I replaced my factory stereo in my 06 Lancer Evolution MR with a 400w component system that sounds unbelievably crisp. However, I lost all of the bass of a coaxial speaker so I wanted to replace it. With weight being counter-productive to performance, I seen this and the rave reviews and it was a must have. Perfect for my situation and it sounds like it has some surprisingly good bass too. [ Dustin  Apr 15, 2017 ]
My system is lacking bass, this seemed like a good option compared to a amp somewhere and a speaker box. [ Jason  Apr 07, 2017 ]
Chance recommended this as a good entry level sub. I installed in under the driver's seat of my '97 Jeep Wrangler TJ. It's hidden, protected from heat/rain, and easy to run wires to and adjust inputs. My only concern on location is I have the controls facing the back seat, so there is a possibility of someone kicking it. Luckily the backseat is so small that most people won't want to ride there. [ Mark  Apr 06, 2017 ]
compact size and powered for easy installation [ JIMMY  Apr 05, 2017 ]
to get more low end at lower volumes and not make the door speakers work so hard [ john  Apr 04, 2017 ]

Perfect size, great reviews around the internet; everyone raves about the tight sound who's installed it, good value, will be a nice upgrade for my wife's old Toyota Rav4, don't need to install an amp. [ Michael  Apr 01, 2017 ]
fits under seat [ U  Mar 27, 2017 ]
3 Years Warranty, great specifications [ Florian  Mar 26, 2017 ]

Need a little more "oomph" in the daughters Jeep. [ Brian  Feb 28, 2017 ]
This will fit under my NON power driver seat and not take up room in the cargo area of my 3rd Gen 4runner [ Anthony  Feb 27, 2017 ]
I wanted a good subwoofer that would compliment my 2 Polk DB521's and my 2 Polk DB402's. After reading many reviews, I choose the Sound Ordnance B-8PTD subwoofer over the Kenwood KSC-SW11. I felt the B-8PTD was the superior of the two. [ InstallerKing1  Feb 25, 2017 ]
Small form factor, medium power, auto turn-on, remote level knob, both speaker level and line level inputs; very convenient for some quick bass boost. [ JOSEPH P  Feb 21, 2017 ]
Looking for something low profile and cheap to boost my factory speakers. [ shaun  Feb 20, 2017 ]

Repeat purchase [ J  Feb 17, 2017 ]
Highly recommended online, price point, remote gain, simple design, and ability to install it with the stock system still in place. [ Jonathan  Feb 12, 2017 ]

I mounted this behind the seat in a Mazda Miata and wow does it fill that little space with awesome sound. It really completes the sound in the car dramatically! Easy to install and easy to set up, great purchase. [ Gary  Jan 25, 2017 ]
meets my needs [ A  Jan 21, 2017 ]
Subwoofer sounded like a good idea, suggested based on stereo choice I made and price seemed reasonable, had good ratings. [ S  Jan 19, 2017 ]
looked like a good idea for boosting the base of my factory speakers [ G  Jan 18, 2017 ]
The stealth aspect and the recommendations from several tech and customer service people. Also the comments are very positive [ ROBERT  Jan 13, 2017 ]
We want some more bass punch, but not enough to shake the doors off. That's crazy! [ Jeffrey A.  Jan 13, 2017 ]
perfect for what I needed. It fits under my seat and seays out of sight. [ charles  Jan 12, 2017 ]

I chose this for the compact design. It will go in my son's 2001 Toyota Tacoma and I didn't want a sub-woofer to take up too much space. I felt this was a good compromise in size and performance. [ Patrick  Dec 17, 2016 ]
Reviews were great and looks easy to install. [ Christopher  Dec 11, 2016 ]

Bang for the buck. It's for my wife's car / family truckster so it doesn't need huge bass. Can be hidden under the front seat so it won't take up space. Should be great! [ Eric  Dec 01, 2016 ]
I only have a small space and don't need a ton of bass. It takes the bass out of the doors and it makes my system sound like it has amplifiers powering everything! [ Thomas  Nov 29, 2016 ]
fits under the seat of my 1994 Tercel [ Dan  Nov 29, 2016 ]

What I needed within budget [ Isai  Nov 25, 2016 ]
Previously had this sub/amp combo. I found the product to be quite capable of providing the increase in low end sound that was needed for my vehicle. My previous B-8PTD failed after a year of use, but sadly I did not install the amp in the car for nearly 3 years prior, so I could not use the 3 year warranty. The failure came when a tech at a speed shop turned up the radio nearly all the way up, which for some reason caused the product to fail. I never turn my system up to max anyway. [ E  Nov 24, 2016 ]
This is the second one I have purchased. After 5 years, the original still sounds great in my Tundra, so I picked up another for my Subaru. [ Eric  Nov 24, 2016 ]

I installed a CD Head Unit into my 1972 Datsun Pick-up, don't have much space in my cab or behind the bench, I bought a bass tube it didn't fit behind the bench. This Sub fit nicely tucked under the bench. The bass is not as good as the Bazooka Bass Tube, but it works for what it is. I recommend this for tight or limited space.

I did some research for an all-in-one sub and this was the best choice! I bought this for my Subaru WRX, paired up with the stock radio and was very impressed with the bass! Produced outstanding sound without annoying the neighborhood. Fits perfectly right under the seat and installation was very easy. Took me about 30-45mins to install.

Decent bass, in a little space, is what I was looking for. Don't hesitate to buy this. I had it in my '10 Tacoma, then moved it over to my F-150.

I would call a Crutchfield advisor. It depends on where you decide to mount the sub. It needs air, they can assist you with your mounting options [ CRAIG I.  Mar 28, 2018 ]
I purchased this sub for my golf cart. Really easy and pumps out ample bass crazy as that sounds. You will need three things A power wire with a fuse coming from your battery tor speaker 10-12 Guage crutchfield guys may correct me on Guage of wire A remote wire coming off your alpine unit to your speaker And lastly you will need a set of good rca cables to run from your alpine deck to speaker. Hopes this helps! [ John  Mar 28, 2018 ]
I recently got mine installed. It needed a sub wiring harness that I got from the place I had install it. It sounds AMAZING. Just enough bass. Really makes the music pop. I know crutchfeild sells the harness u need for this. Hope that helps [ eric  Mar 28, 2018 ]
The Sound Ordnance B-8PTD is a powered subwoofer so, it comes with a built-in amplifier to power the built-in sub. As a result, it does not need to be "driven" by your stereo; it just needs the audio signal from the stereos's RCA pre-amp outputs. You will need to add a 10 gauge wiring kit for a proper install: For additional assistance and personalized recommendations, feel free to contact us directly by phone or through our online chat service: [ Ryan  Apr 03, 2018 ]  Staff
It should fit under any seat. [ Dolores  Feb 05, 2018 ]
If you have clearance under the front passenger seat and don't mind losing some potential foot room it should fit there and you can route the cabling in the center console. That worked in my Accord but lost a little foot room for the back seat, just pu the floor mat against it like a wall. [ Christopher  Feb 05, 2018 ]
They don't seem to do well in the cold. I've had 2 units fail when it was cold. Crutchfield covered both under warranty and are very easy to work with. Hope yours comes around or has a warranty still [ Dustan  Jan 31, 2018 ]
Not by design. sounds like a loose connection that completely seperates in cold. [ randy  Jan 31, 2018 ]
I had the same problem, I called Crutchfield and was told that the sub needs to warm up. [ CRAIG I.  Jan 31, 2018 ]
You'll need power & ground cables for sure (10 gauge minimum). If you will be connecting to an aftermarket stereo, you'll also need RCA cables and a remote turn-on lead. If you will be connecting to a factory stereo, you'll need some wire taps and a bit of speaker wire to connect to the subwoofer's "speaker level input" harness. For additional assistance and personalized recommendations, feel free to contact us directly: [ Ryan  Jan 01, 2018 ]  Staff
Subwoofer cable and remote cable. [ Tawna  Nov 26, 2017 ]
I polurchased the wire harness for my truck with this. I had to run the power line and two input lines from the stereo to the sub. Additionally there is a remote line for volume control to run. All in all I am a regular Hanley man around the house and this was not very hard. Hardest part was to drill power line thru fire wall to get into car. [ Matthew  Nov 26, 2017 ]

Installation of one speaker was relatively easy providing you purchased a wiring kit and the head unit had preamp jacks - which mine did. Installing 2 units is a little more challenging. If you are looking for more sound then i would install a larger speaker. If i recall correctly -I believe they have a 10 inch model. If you head unit has multiple preamp jacks - then just purchase another wiring kit. Another option is perhaps using the speaker leads but you may not get a pure clean sound. I am not sure that installing 2x8 inch speakers is the right way to go unless you have a space or other limitation. For the cost of 2 x 8's - you would be much happier with an enclosed sub box. Perhaps look st google or youtube for more information. If i were to do this again - i would have gone in another direction. [ andrew  Oct 03, 2017 ]
Call Crutchfield and speak to one their advisor's. They are very helpful. If it can't be done they will let you know what options you have. This is not Best buy [ CRAIG I.  Oct 03, 2017 ]
If I had to guess, because I don't have the Ford sub, that it is probably the same amount of bass. This sub doesn't hit very hard, but makes the rock and roll and other non bass centered music sound good at loud volumes. If I had to do it over, I'd get a bazooka. [ CLAYTON M  Aug 09, 2017 ]
It fit under the backseat of my 05 Silverado. However I would read the demensions under the Specifications tab. Then use a retractable tape measure and measure under your seat. Common sense, right? If you need someone to answer your question please call a Crutchfield advisor. [ CRAIG I.  Jul 11, 2017 ]
It fit under my driver seat in a 2003 Tacoma. [ Thomas  Jul 11, 2017 ]
I have it under the driver's seat of my 2014 Kia Forte so I would imagine a 4Runner would have a lot more room under the seat. Check out the dimensions under the specs to make sure. The hardest part about installing under the seat was getting a spot to anchor the ground wire without having to remove the whole seat. I was able to do it and have never installed any audio equipment before. I have been 110% happy with this sub - I wish I could put one in my other car as well. [ Jonathan  Jul 11, 2017 ]
I don't see why not. I have 2 in my Ford Ranger behind the seats... great sound in such a small package. Love them [ BRIAN  Jun 21, 2017 ]
Adding another Sound Ordnance powered sub to your system will likely help improve the overall bass output. For more details or to discuss further, please feel free to reach out to an Advisor directly by phone (888.955.6000) or online chat. Thanks! [ Larry  Jun 18, 2017 ]  Staff
Crutchfield folks are better qualified to answer. Really no good fit. Obviously, for best performance needs to be mounted. Mine is in my daughter's LX450 just floating around the cargo area. Mounting to the floor is not an option, as the vehicle has a third row of seats that are sometimes used. I believe that Crutchfield suggested the back of a seat as a mounting point if you want to investigate. In your case, I would just attach to floor if you do not mind the intrusion to your cargo space. The unit seems very durable and will tolerate some cargo on top of it if necessary. Not familiar with your vehicle, but if it has the small rear seats, perhaps is room under one of those - bass does not care where it comes from. Again, I defer to Crutchfield - have been dealing with them since 1977 and they are great. Good luck. [ CLARENCE  Jun 05, 2017 ]

We have a 98TJ. It's mounted under the back seat. I'm not sure if the JK's have the same clearance, but it's snug between the floor pan and bottom of the seat. Still sounds great. The low frequency doesn't seem to be affected at all. [ Kyle  Apr 17, 2017 ]

Mine is about 2 years old and working well. I would call crutchfield since this is made for them for amp suggestions. As long as you match power, size and ohms you should be fine [ DAN  Jan 26, 2017 ]
The amplifier is a class c amplifier, so i would recommend the same type, not sure about brands or model. I recently changed the car and I pulled it from the old car. [ Freddy Jose  Jan 26, 2017 ]
Not likely. Damage to the amps may result. The remote doesn't carry standard audio but a control voltage for the amp. Two amps may interact through the splitter and damage the control electronics. [ William  Jan 18, 2017 ]
Interesting question... I assume you refer to a standard RJ11 telephony splitter? Don't see why not. If you try it let us know how it goes. [ Pat  Jan 17, 2017 ]

My 13 Silverado crew cab didn't have connectors. I had to run the lines along the doors. [ NATHAN  Oct 17, 2016 ]
Most likely, yes. In a full size pickup, you should have numerous options for mounting this sub as it is pretty stealth. I put it behind the rear seat in a Tacoma just to give you some comparison. You only need to locate one speaker cable in your rear doors to give the sub the audio signal it needs. The bigger challenge will be connecting the power cable which will need to be fished up through the firewall, into the engine bay and connected to the battery. Crutchfield has all the tools you'd need to do it yourself plus videos. Still, I was more than happy to take the sub to a local shop and pay them to install it, especially given the tight working space of my Tacoma. The sound is impressive, especially for the size of the unit. You will notice the improvement right away. Keep your expectations realistic - it's not going to win any sound offs at the local mall parking lot - and you will be very happy. Then, of course, you'll want to ditch those Bose speakers but that's another post... Good luck. [ Bruce  Oct 17, 2016 ]
I have mine in a Jeep Wrangler and I too had that issue after wheeling it pretty hard. Mine was an issue with the cable that plugs into the unit to control the bass level. I eventually replaced that cable and it solved the issue. I hope this was of some help. [ David  Oct 18, 2016 ]
Hello Sam ! This sub has three wires connection : One permanent power supplied from battery,one trigger power supplied from your stereo player to turn on the unit and last one is ground supplied usually from body ground.if your amp/sub lost connection from one of the three,it will not work.Check your connection especially the ground connection from amp/sub mounted to body.Sometimes under excessive vibrations it became loosed created bad or no ground supplied to this unit intermittenly..if all connections are good,suspected internal components connection issues and it may need to be repaired or new unit need to be installed.Hope this help.

Our mechanic wired ours from the underdeck in a 1996 Volvo 850 Stationwagon to a new Alpine sound system. He said it was a "piece of cake." Sorry I don't have more details. [ Earl  Jan 28, 2017 ]
I don't have the same vehicle as you, but was able to use the RCA outputs on the back of my Alpine head unit and run the cord under the floor mat for a clean look. Ran the power the same way. There were some rubber grommets that I passed the wires through. The sub itself takes up very little space and that went under the front passenger seat. Overall sound from the dub was decent, nothing that will rattle your windows, but provided a nice low end for the 4x6 speakers in my F-150. I'm not a professional installer, so it took a couple hours. Hope this helps [ JASON J  Oct 12, 2016 ]
We didn't measure the space under the seats in Ford Escape we researched. We measured the rear cargo area under the cargo cover. If I had to guess, it will be a close fit as this powered subwoofer has a foot print that is 9-1/8" wide and 13-5/8" deep. It needs 3-1/8" for height. I've used poster board before to make a model to see if that would fit. You might give that a try. HTH!! My Bio: [ Paul  Sep 18, 2016 ]  Staff
i wired mine directly off the rear speakers thru the speaker level inputs. this unit will also turn itself on when it senses the speaker power and off when it doesn't so from there all you need is a power supply. not to difficult. [ Jim  Aug 29, 2016 ]
Crutchfield can send you everything you need to make your installation a success. In fact they can answer any questions you have even while your installing it. I actually own two of these and have them mounted under my two front bucket seats in my Nissan Juke. Decent subs for tiny places. [ RANDALL  Aug 17, 2016 ]
Check out the line level converter from Crutchfield and ask them the color codes for your speakers wires. The will walk you through the install [ GREGORY  Aug 17, 2016 ]
It seems to be, but mine does not get much abuse. It sits under the front passenger seat, and I don't have rear passengers (who might kick it) very often. [ waterdog  Sep 01, 2016 ]
Yes it has been in my one ton duramax on jobsites bouncing around and still sounds great [ Alan  Aug 05, 2016 ]
Yes, I have found the unit to be very durable and reliable. I have it installed under the back seat in my Silverado, and am very pleased with the sound, and it was easy to install. [ Danny  Aug 03, 2016 ]
Yes it seems to hold up well [ John  Aug 02, 2016 ]
I had the unit mounted to the back wall of my truck. It had groceries thrown against it as well as a rambunctious 8 y/o back there. I never had any problems with it. So, more succintly, yes it is pretty durable. Hope this helps. [ JAYSON A  Aug 02, 2016 ]
I have this setup in the back of my Jeep Wrangler... It's a fairly rough ride and this unit has held up well so far. It's been installed for approximately one year now [ GREG  Aug 02, 2016 ]
I've had it bouncing around under the back seat of my truck for a couple of years now with no issues. That being said, if your looking for "thumping" bass it's not for you. It adds enough bass for me. [ mark  Aug 02, 2016 ]
I put this in my 2001 BMW Z3 2 years ago and love it, fills the car with base. [ DAVID A  Aug 02, 2016 ]
Yes, it's built well. If you have limited space its a good powered sub. Doesn't get the low bass very well, but I was happy with it. [ Paul  Aug 02, 2016 ]
I had two mounted/actually just sitting behind my bench seat in my 2002 ford ranger single cab with the seat all the way back. Fit like a glove. [ RANDALL  Aug 17, 2016 ]
Yes. Two mounting clamps are provided to secure the woofer to a flat surface. You will find this information, and more, by clicking the "Details" tab on the woofer's main webpage and scrolling down below the "Features & Specs" table. I hope that helps! My Bio: [ Ryan  Jul 30, 2016 ]  Staff
Bought to add some affordable bass to an alpine unit. No amplifier. Listen to country mostly. May want to research a little more [ Geoffrey  Jul 20, 2016 ]
It probably depends on the size of your car, but I would say probably not. This sub rounds out the bottom ranges nicely but doesn't "hit" like bigger setups. Does improve the factory setup though [ Andrew  Jul 20, 2016 ]
No, it does not have a lot of deep bass. [ Jeremy  Jul 20, 2016 ]
Jaden, I am more of a jazz guy so wasn't looking for a whole lot of super fat bottom end, there may be other subwoofers that would serve that better. But that being said it does seem to be really full and fat sounding for such a small unit, and the price is right [ Robert  Jul 20, 2016 ]
It depends on how much bass you want. This unit works good if you are looking to add more bass to an audio system, but if you are looking to rattle your windows you will need to look elsewhere. [ John  Jul 20, 2016 ]
Power off the battery or fuse box to an on/off switch, then to the remote out terminal on the Sub. [ RANDALL  Aug 17, 2016 ]
Switched line only. That way the amp will only come on when you send 12 volts to it [ GREGORY  Jul 16, 2016 ]
Yes you can. I have two in my Nissan Juke. [ RANDALL  Aug 17, 2016 ]
It is possible to install a second powered subwoofer into a vehicle. The gear needed to do this will vary depending on the system and the wiring used to install the first one.

Not a signal wire. I just ran one wire from the back of my head set to the sub and one wire from the sub straight out to the battery that has a fuse in it. [ mark  Jul 20, 2016 ]
I just installed this sub in a 2015 GMC Sierra. I tapped into the rear speaker wires. I did not install a remote turn-on lead at first. The sub only turned on momentarily and then would not work at all. I called Crutchfield technical support and they said this was a common problem. The solution is to go ahead and install the remote turn-on using a switched power source. I did this and it works flawlessly now. Don't forget to turn the 'Power Mode' switch on the sub to 'Remote Wire'. BTW this is the 3rd one of these subs I have purchased. It is a great sub for the money. [ RONALD  Jun 16, 2016 ]
The spec sheet says it can do this operation thru the high frequency wiring (speaker wire); however, I attempted this install and the power on was intermittent. It would sometimes turn on and sometimes would not. I ended up just running the remote connection to my fuse box and tapped in to one of the fuses that turns on with the my F150 was the seat warmer fuse, which my truck does not even have. Good luck. [ Greg  Jun 06, 2016 ]
I ran a power lead to mine so the head unit would turn it on I saw no info on hooking up additional speakers since it's self contained with the sub speaker built in ? [ Ernie  Jun 06, 2016 ]
I ran one to mine and it works great. [ CHIP  Jun 06, 2016 ]
It needs power ran from the battery. You can tap into a speaker for input, but not to drive it. [ Brandon  Jun 06, 2016 ]
This is for all of the available compact subs, I would recommend to contact an Advisor by phone (1-800-324-9695) or online chat. They will be able to pull up your vehicle, compare the different subs available and give you the details on if they will fit and what you will need for an installation in your vehicle. [ Kenny  Jun 03, 2016 ]  Staff
The Sound Ordnance powered sub requires its own power and ground connections. You should run a power cable directly from the battery to the sub. Also, you need to install a ground cable from the sub to a metal part of the chassis. You need to buy a good quality Amp Power Kit which contains both power and ground cables (I like the Rockford Fosgate 10 AWG). You will definitely need some type of signal wire to turn the sub on.You should have a connection on your new head unit's wiring harness. A backup plan is to connect to the red (ignition) wire. Hope this helps. You have bought a very good sub! [ RONALD  May 05, 2016 ]
You should be able to use your existing wires, just make sure you have an inline fuse in the power wire. You will need a signal wire from your subwoofer to your head unit so it comes on when you turn the head unit on. [ RANDALL  May 04, 2016 ]
I would run new, they need to be the right gauge wires, factory won't be. For signal wire I would use remote power lead that comes from your aftermarket deck. [ JEFF  May 04, 2016 ]
My install did not have any pre existing factory wiring so I had to run everything from scratch. I do not see any reason that the factory wires might be fine to use. I would call the manufacturer to be sure [ PAUL  May 04, 2016 ]
The power and ground may work for this new set up. If it were me, I would run new wires as the factory ones are as cheap as you can get. However, this set up does not need crazy thick gauge so it may be okay. You do need a signal wire, I spliced from my fuse panel for this. Just pick a fuse that turns on with the ignition, I used the seat warmer fuse. Feel free to ask anything else. I really like this set up, it is exactly what I wanted for my system. Def not something trunk rattling but upgrades it from stock for sure. [ Greg  May 04, 2016 ]
If factory amp is equal or less watts as s.o . I think it's 125wts. Run signal wire from antenna wire on head unit. Turns it on and off with ignition switch. I have two of these in a titan truck. They do exactly what I want [ GREGORY  May 04, 2016 ]
Not sure this will help but I installed this sub in a 2002 Honda Accord. I put the sub in the trunk, just behind the rear seat. Ran all the cables on the passenger side, underneath the door thresholds. The only significant issue I had was finding the firewall penetration for the power cable to the battery. Once I found the rubber grommet that covered the hole, everything went pretty smooth. [ RONALD  Mar 31, 2016 ]
sorry I can't answer your question. I have a ford ranger XLT 2002 and I was hopping to put it under my seat. I missed my goal by a half an inch. I am happy with this unit and where I ennded up putting it. you might not be hread a mile away but it sounds great inside my vehicle along with the head unit and speaker upgrade I had done. [ JAMES J  Mar 30, 2016 ]
Put one under each front seat of 09 titan king cab and had plenty of room left over. Just bought a 13 titan crew cab, too much electronics under passenger seat so I put them under back seat. Love these things! They sound great for my style of music. [ GREGORY  Mar 30, 2016 ]
Yes they will. [ RANDALL  Aug 17, 2016 ]
Can't say for sure. I have an extended cab so I inserted it from behind the seat. Plenty of vertical room, but it will depend on whether the handle to slide seat gets in the way. [ Nicole  Feb 12, 2016 ]
According to the Crutchfield web site the dimensions are 9-1/8"W x 3-1/8"H x 13-5/8"D. I haven't measured mine but those numbers look right to me. I have mine located under the rear seat of a full size pickup truck (lot of room). My signal inputs are from RCA patch cables that are connected from the head unit (receiver) to the sub. I believe you can also connect this sub to your existing speaker wires using the line level inputs. Crutchfield has great technical advisors who can walk you thru this. This is a great powered sub for the money. Excellent sound and quality (note the warranty). It is not designed to 'blow the roof off' of your vehicle but it will add very good depth to your music at normal to moderately loud volumes. Highly recommend! [ RONALD  Jan 19, 2016 ]
Dimensions are listed...Width9-1/8",Height3-1/8",Depth13-5/8"...this seems accurate based on my memory (vehicle was sold). I located under the passenger seat of RAM1500 without problem. You can go either way regarding source (speaker or sub-out of head). I used single sub-out of head. For the size and price, I was happy with it. Note that you'll likely have to route power all the way back to battery of vehicle. [ Jon  Jan 19, 2016 ]

Nope sorry. Jeep Cherokee. Really sounds nice once it's balanced [ Thomas  Dec 15, 2015 ]
No I have not installed in a Saab. Watch out, it is kind of large(for under seats) but it should fit in the rear hatch area. The unit sounds great! [ MIKE R  Dec 11, 2015 ]
The wiring kit they advised I get for this was a 10 gauge kit and I think it had a 30 amp fuse. But just just check the wiring kit they have to go with it and see what fuse it has. [ william  Nov 15, 2015 ]
If you pop a 30 with this you have a dead short and it did its job. 30 should be plenty! [ TIM  Nov 15, 2015 ]
I am in the same boat as you, I want to move my 8PTD over to my new 2015 F150 Screw. As far as know, no one has a harness for our stereo to give us the RCA jacks we need. So, the thing we need to do is tap into the rear speakers and tie that to the high level input on the sub. There is a thread for it on one of the F150 forums, just do a search for something like "2015 F150 adding subwoofer" [ RANDALL  Oct 01, 2015 ]
wish I could help just don't know works great in my s10 [ LARRY  Oct 01, 2015 ]
I bought this sub for my truck because it fit under the passenger seat it's not huge pounding bass but if you like a nice added base to a normal system it sounds great it's very adjustable work perfect for my situation again it adds a nice bass sound to a normal system, not for huge thumping bass [ russell  Sep 24, 2015 ]
Kinda hard to just put a number on it. Is it as good as my Infinity Basslink, no. But then again it fits where the basslink doesnt. I would say its a nice addition to a stock system. Better than mkst factory subs I have heard. [ Aaron  Sep 24, 2015 ]
For an 8 inch compact sub woofer I would give it a nine. I was pleasantly supprised on the amount of bass. I was looking for something to fill the low end in more on my stock radio setup. People are supprised when they sit in the truck and see what is producing the bass. It is also easy to hide inside the vehicle for a stock look. I have installed one in each of the two trucks I own. [ Tom  Sep 24, 2015 ]
Let me first start off by saying if you are looking for bass that you would hear outside the car then this is not for you. I would rate it at a 7 for a full bass sound for small tight places. [ JOSH  Sep 23, 2015 ]
For the size of vehicle I installed this into (small 2 seat car), I would rate it at a 9. If the vehicle is any larger than two seat sports car or regular cab pickup, I think the sound will diminish drastically. If you are wanting heavy bass for a crew cab pickup, suv, or large four door car, this is not what I would choose. [ Homer  Sep 23, 2015 ]

I installed mine under the front passenger seat of a 92 BMW 318ic. It was very tight but fits without rattling anything. I have another one behind the seat of a sprinter van but it does sound better under the seat. [ ALEXANDER  Aug 26, 2015 ]
I can't see why it wouldn't work if it fits now if the heat is blowing directly on it would not want that air be fine [ LARRY  Jul 27, 2015 ]

I and my son installed one in a Ford Explorer, it was simple and straight forward. Hardest part was feeding the power cable thru the hole I drilled in the fire wall. Its a decent SW at a great size and price, its added a nice thump to the Kenwood headunit and 6x8 door speakers. [ ROBERT  Jul 03, 2015 ]
I Installed this under the drivers seat of my 97 wrangler. There is room, but I had a little extra because I have given the seat a "lift" for my daughter who is shorter. Ran a new power cable to the battery and remote power to the head unit. Get a good ground to the seat frame or body as close to the sub as possible. It sounds great. [ DAVID  Jul 03, 2015 ]
I don't know about your Jeep Wrangler but I installed it in my Silverado. The hardest part was running the power cord from the battery to the unit. It took forever to find a viable hole through the firewall. Once the power cord is run and connected just pull your head unit and plug in the supplied speaker wires into the head unit and then run it to the subwoofer. Then plug in the volume control and there you go. It's as simple as that. [ EDWARD C  Jul 03, 2015 ]
Find out the height of the seat to the floor the Crutchfield rep will know that information. The 1193 King cab Nissan truck it did not fit under my drivers seat so I returned it. I am not sure about the height of the 2006 Frontier King Cab but a rep will be able to tell the height of the amplifier it is pretty tall so do not forget to measure from seat to the floor and a rep will inform you the measurements of the amplifier is Good Luck keith [ KEITH  Jul 05, 2015 ]
There are size measurements on the site..... 9 1/8" wide, 3 1/8" high and 13 5/8" long... not go get a tape measure and have at it. [ CHRISTOPHER L  Jul 03, 2015 ]
Mine fit under the passengers seat of a 2000 Dodge Stratus. The dimensions are listed if you need to measure. [ ZACHARY  Jul 03, 2015 ]
no. BUT. these are tough units. I have one in the floorboard of my wrangler, and this is not a mall-crawler jeep. I would just say go to whatever trouble you need to keep it as dry as possible. I would incorporate something using the bell-jar affect . Dude, you're gonna have to think "outside the saddlebag", it will be so worth it. [ CHARLES J  Jun 26, 2015 ]
NO, it sounds interesting though, it would probably work as long as you can fit it in, [ ALLEN  Jun 26, 2015 ]
If you plan on playing your music at a whisper, then yes you could. Otherwise it is a no. The reason for this is that your radio usually has a 10 amp fuse and a 18 - 20 gauge wire (think really small) and amps will run 25 plus amps. This will constantly blow the fuse for the radio. Now you may be thinking "Hey, I'll just use a bigger fuse". Sounds great, until your dash starts to smoke and potentially catches fire. This would be caused by the wiring overheating. So as you can see, it is better to purchase a amp wiring kit and do everything right, then to try to go on the cheap and have nothing but trouble later (which in my experience always happens). Best of luck! [ BRIAN  Apr 28, 2015 ]
I would not piggyback from head unit power. You need to run a dedicated power cable from the battery to the amp. The power wire should also be fused within a foot of the battery. [ Tom  Apr 27, 2015 ]
No it requires enough power that the small power wires running to a head unit will not provide enough power. Best thing to do is to buy an amp install kit and run a separate power wire from the battery to this amp. [ JASON R  Apr 27, 2015 ]
I would not advise it, this requires a 10 gauge minimum power wire. [ Anthony  Apr 27, 2015 ]
No interference at all. Make sure you run the power supply down one side of the vehicle and the speaker output down the other side as the directions instruct you to do. A little more work but no interference. [ EDWARD C  Apr 26, 2015 ]
I have seen zero alternator noise on my SO B-8PTD. While this is not a perfect device, it certainly beefs up any typical audio system with minimal space and effort. I highly recommend the device. [ Jonathan  Apr 24, 2015 ]

I have experienced none, just make sure you have a good ground. [ Eric  Apr 24, 2015 ]
None in my setup. If you have alternator noise it is your wiring or power source not the amp. Invest in good wiring both for power and signal. [ Andy  Apr 24, 2015 ]
I have one under a 2014 Versa Note drivers seat. If you aren't sure take measurments and maybe even build a fake one with cardboard. This unit is unlike most subs that it was designed to fit under most seats. [ Andy  Apr 24, 2015 ]
No... Most seats are too low to be installed there. I installed mine on the center floor rear seat. Or, you can install it in your truck as long as you have extra long amp cables. [ MIKE  Apr 23, 2015 ]
i put this exact one under the passenger front seat of my 04 wrx which is essentially the same thing. so the short answer is yes. i ran the wires down along the passenger side doorway under the carpet and it comes out in an opening under the seat where the airbag wires come out. works perfect there. [ william  Apr 23, 2015 ]
I do have one under a 10 Outback and it barely fits. That's the best I can do. Maybe nasioc dot com could help. That is where I heard of this sub [ SHAWN  Apr 22, 2015 ]
I was getting that with the original setup that was home done, but had the job finished off at a pro shop and the thump is gone now. Like William said though, it's just at startup and not that big a deal. I can't tell you what they did but they know how to wire car stereo. [ Andy  Apr 24, 2015 ]
mine always gives a little thump when i turn on the head unit on. no big deal just does it once then its fine and works its normal and dont worry about it. [ william  Apr 23, 2015 ]
Some after market decks have a remote turn on lead, and a power anteena lead. They're both usually blue so it's easy to mix them up, might want to double check them. If that doesn't work, try finding something else that is switched on with the radio, maybe the fuse for the radio? [ EVAN  Apr 17, 2015 ]

i have an '06 wrangler, same jeep body style. I cut a piece of 3/4 marine plywood to fit the contour of the pan behind the drivers seat. The amp is sitting on top of the plywood. The plywood is only to raise the amp off of the floor a little to keep it from getting wet when water makes its way into the pan. That's gonna happen if you have a soft top and live at the beach. Used industrial strength velcro to attach amp to plywood to keep it from sliding around. Hardly ever have more than one person in back seat, so it works out. This is one tough amp and it sounds great. Two years of rain, sand, surfing and it hasnt missed a beat. An option is to mount on inside of tail-gate, but with a soft top, that location is a little more exposed. I keep a heavy plastic bag under the driver's seat for the occasional monsoon/no doors/no sides scenario. Usually i just throw a towel or two over the amp [ CHARLES J  Feb 17, 2015 ]
if u buy this, u will promptly install in a circular or square garbage container. I bought 2. I was not functioning properly. the other worked but was hardly worthy of the term "sub woofer". It's weak [ ABEL  Feb 17, 2015 ]
You could wire them to other speakers the same way so that multiple speakers get the same signal but make sure u do both polarities correctly and the same. Also the power available to those speakers won't change so each will only get half whatever it had to start out with. [ william  Nov 15, 2015 ]
Depends on the set up, but generally speaking , no. [ TODD  Feb 16, 2015 ]
As long as it clears the frame, sliding back and forth wont be an issue. Very low profile. [ MARK  Feb 03, 2015 ]
Yes, that is where i instaled the one i had.....passenger side... [ RONALD  Feb 03, 2015 ]
Yes all of this can be hooked up at home using a PC power supply, and some ingenuity! I have done this in the past, it can work very well. I highly suggest to look for instructional videos on YouTube, you will find many there. [ EVAN  Dec 24, 2014 ]
You just need to find a regulated 12 volt dc power supply that can deliver about 10-15 amps. That should be powerful enough for the sub and a moderate radio. These power supplies are electrically clean, linear, and commonly used by cb and ham radio guys because they don't produce any hum that would then bleed into your gear. You then just plug the power supply into the wall and you are ready to start hooking up all the stereo gear. That said, the sound ord box isn't built for a large room in a house. It won't sound as good as a regular sub box built for homes. [ JON  Dec 24, 2014 ]
I wish I could, but not sure about the power hookup, sorry [ ALLEN  Dec 24, 2014 ]
no, 2002 Nissan Frontier P/U, if you need help let me know. I love the unit and the sound but it did not really fit under the seat. I had to mount it in the rear seat area of the truck. Good luck my friend. [ FRANCIS A  Dec 22, 2014 ]
I bought 2 of these with plans to install them under the front bench seat of my 75 Impala. One arrived defective...and the other worked but was not impressive. I wouldnt buy these again and wouldnt recommend them [ ABEL  Dec 19, 2014 ]
No, I have it in my 2006 corvette, sound great it fills the hole car, going to add tweeters this year [ HERMAN  Dec 19, 2014 ]
1) I haven't had both styles, but I've heard the self-powered can be a cleaner sound for low power radios because it doesn't draw all it's power from it. 2) Unless you have some kind of opening it'll probably muffle. Mine is under my seat, and it sounds fine. Locate the remote control near you and you can adjust it for your comfort. I found that I need to do this a lot, my playlists have a lot of difference in response. [ FRANK J  Dec 18, 2014 ]
I cant answer first question because I've never owned a non powered sub. I think under the seat if room allows would be the best place. [ MARK E  Dec 17, 2014 ]
I have it under the back seat in my truck and it does pretty well [ MARK  Dec 17, 2014 ]
I put this sub under the rear seat of my F150 and I'm very happy with its performance. Never a complaint from the rear passengers considering how thin those seats are and you can adjust power levels accordingly. I play load rock and blues and occasionally rap. I have no experience with the difference between self contained or powered. [ BRADLEY  Dec 16, 2014 ]
I placed this sub-and-amp directly under the front seat of my 2006 Nissan Frontier. I originally had them place it directly between the two seats, but the techs moved it as it wasn't sounding good. NO trunk. Not that kind of sub. You're better off with a traditional component setup or a Basooka setup in that case. Under the driver's seat will work - but bear in mind that it works best in minimal space - think roadster (miata) or truck cab. I hope this helps! [ JOHN J  Dec 16, 2014 ]
Invest in the line converter hardware. I used a line level converter on my factory head unit and after I followed instructions on how to get the right bass sound, it was great. Great sound for a compact unit. Be sure to follow instructions on how to use the features to get the best sound. [ MARK  Dec 16, 2014 ]
cant help i bought new head unit and speakers but the sub is a nice unit [ KEVIN  Dec 16, 2014 ]
all u have to do is wire it in to your rear and that's it [ MELVIN J  Dec 16, 2014 ]
You can mount the unit under seat or in the trunk. Purchase the wiring adapter specifically for your vehicle. The unit comes with complete in instructions, but you will need to find the best place to run your power from your battery. In most cases you can get this information as a how to on YouTube. It will show you how to get the wire through your firewall to the sub. I am very happy with this unit overall. It provides the punch I wanted in combination with the after market receiver and four speaker upgrade I had already purchased from Crutchfield. [ JOHN J  Nov 12, 2014 ]
If you have audio outputs at the radio that's supposed to be the best way to tie it in. My car doesn't have that, I used crimp connectors that hold the wires and then crimp onto the existing wires. I bought these at an auto parts store in town, the "tap-it" connectors I initially tried had bad connections, possibly because of the wire size the factory used. I put the amp under my seat with the velcro and it's worked out ok. I would definitely use the remote volume control, my cd/radio/usb all seem to have a little bit different response, and it beats trying to reach under the seat to adjust it all the time. Tie the power in so it comes on with the ignition switch, the auto-on function can give some delays that sound funky, and I don't think cycling the power on and off like that is all that good, either. If your speakers are easy to get to, try them with and without the filter caps to see which sounds the best to you. The filter caps reduce the low frequency response at the regular speakers and allow more power to the amp, but it didn't seem to do that much for mine, and might have rolled off too much mid response on my system. In any case, I've had little problems with it, and you'll like that extra punch in the sound. [ FRANK J  Nov 11, 2014 ]
The Sound Ordnance B-8PTD is self-powered with a 125-watt dedicated amplifier included in the enclosure with the 8-inch sub. Connect it to your head unit using either RCA patch cables or speaker-level bare wires. If you're looking for a solid improvement (not a huge THUMP) to your car's bass reproduction, you'll be pleased with this compact powered subwoofer. [ CHRISTINE R  Oct 27, 2014 ]
You do not need an amplifier with the B-8PTD it is built in to the unit & is fully adjustable for any system. The only thing you need is an amp wiring kit. However, if you have aftermarket head unit & speakers installed in your vehicle you might want to get the Alpine KTP-445U Power pack to boost the sound of your other speakers it is awesome & easy to install. [ TODD M  Oct 26, 2014 ]
no , amp and sub are 1 unit [ JAY  Oct 25, 2014 ]
No, It has one built into it. [ EVAN  Oct 25, 2014 ]
No. [ Michael  Oct 25, 2014 ]
No, it's powered. [ ROBERT  Oct 25, 2014 ]
no it has a decent class D amp in it already. i have 3 of these. only one had a problem after 1 year it would cut out. within 3 days i had a new one sitting at my front door. crutchfields cutomer service is what seperates them from the compititon. oh and as long as your not listening to hip hop it will perform flawlessly. enjoy.... [ KENNETH M  Oct 25, 2014 ]
Its powered . [ JUAN  Oct 25, 2014 ]
I can't answer, sorry. I am using the auto on wire to switch on the power amp. The powered sub I have to turn on manually [ JACK  Sep 12, 2014 ]
It has line-level and speaker-level inputs so you can tap into existing speaker leads. It also has auto-turn off plus the ability to power on and off via a dedicated lead off the car radio. You still have to run power to it from a high current source but it can be remotely turned on and off. [ RICK  Sep 11, 2014 ]
I am not sure, but I think when you run the big blue power wire from the sub thru the firewall to your battery, when you turn on your ignition the sub will automatically cut on. You may want to check with and ask an installation or technical advisor from Crutchfield. I do like the sub, it is pretty good overall considering sound, size, and price. [ DAVID  Sep 11, 2014 ]
It is easy to hide the wire in 2nd gen Tacoma. I own two Tacomas and installed one of these subs in each behind rear seat. Trucks look stock with these subs installed. [ Tom  Sep 24, 2015 ]
Installation is simple, and as for hiding the wires that is 100% up to you. You can hide the wires in anything, just how hard you want to work at it. [ CHRISTOPHER L  Jul 03, 2015 ]
We have not received any answers from other customers on your question. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help answer your question. [ Krissy  Sep 05, 2014 ]  Staff
It definitely controls the volume and does it very well. The knob came loose on mine and I had to remove the black metal know and glue it back to the white knob below. Before I did this, the loose knob didn't seem to do anything. [ Machew  Jan 24, 2018 ]
Chuck, I have mine hooked into the head unit with RCA style cables. The remote serves as a separate volume for me, kind of like the bass boost function on some head units. Since some passengers don't prefer as much bass, it's nice to have the option to tone it down without going into the settings or messing with the gain on the sub itself. [ DANIEL  Aug 18, 2014 ]
Yes, that's what it's for but I didn't use adjust the gain, which in tern gives a little more volume, Hope that helps.... [ RONALD  Aug 17, 2014 ]
it allows you to adjust level on the fly. Some music may have different levels of bass. this allows you to adjust accordingly. [ JAY  Aug 16, 2014 ]
The remote controls the volume of the bass output from the sub, but I have found the level of control to be very minimal. [ GLENN  Aug 16, 2014 ]
Hey Chuck, It's a remote bass boost level control for those inevitable times when the final mixdown of certain albums/bands/musical types have varying bass levels. I run mine off the RCA inputs, but it shouldn't make a difference which inputs are used. My bass boost level ON THE UNIT is set at about 50%, and the remote knob makes enough of a difference to level out the boom across the different bands I listen to. Try maxing out the bass boost control on the UNIT, and then use the remote knob for final adjustment at the dash. This may give a wider sweep to the knob control knob. Hope this helps [ David  Aug 16, 2014 ]
Only controls volume, but you should definitely hear a difference by adjusting it. [ T BRENT  Aug 16, 2014 ]
I mounted horizontal, but it looks like it could be placed vertical as well. [ KEVIN  Jun 16, 2014 ]
Yes; you can do either or but make sure you have the necessary application to do it right in your vehicle. Definitely, a good amp. [ JAMES  Jun 13, 2014 ]
Mine is mounted flat, but I see no reason it could not be mounted vertically. [ JAMES  Jun 13, 2014 ]
It can be mounted either way. It comes with adhesive Velcro strips, but if mounting upright I recommend planning on mounting with screws or similar technique. [ RYAN J  Jun 13, 2014 ]
Mine is mounted upright/ on it side so you can acces the wiring. It's behind the back seat of my F150. Works fine! [ CHRIS S  Jun 13, 2014 ]
Yes ca be mounted. Upright. [ EDWIN  Jun 13, 2014 ]
Yes it can be mounted upright. Use plenty of velcro. [ darrenh  Jun 12, 2014 ]
Either way should be just fine. It is a tight little package. [ WADE A  Jun 12, 2014 ]
I mounted it upright and it works just fine [ JOEY  Jun 12, 2014 ]
It can be mounted either way. I have mine laying down, under my passenger seat. If you need to put it on it's side, there are some light duty braces that you can use to mount it on it's side. [ JASON  Jun 12, 2014 ]
Hello, i mounted the unit flat under the passenger seat. However, i dont see a problem mounting it upright given you have a solid mount that the unit can be screwed down to for it not to fall or bang around while the car is in motion. Hope this helps. [ SEVAG  Jun 12, 2014 ]
A quick measurement of the clearance under your front seats and a check against the dimensions of the B-8PTD will give you your answer in a couple of minutes. I found plenty of clearance under the passenger seat of my old 2009 Focus SES (effective and easily-tuned reinforcement of the bass, too, complementing nicely my Boston Acoustics upgrades over the factory door speakers). In my earlier experience with undersea sub installs (1980 VW Rabbit and 1992 Ford Escort), I found that the passenger side front seat tends to have fewer fit problems, as that side is less likely to have height adjusters that can lower a seat onto the sub. Soundwise, there shouldn't be much difference between the two front seat locations, as bass frequencies are mostly non-directional. Might be a bit of difference in the bump the sub delivers to your rump, if you like that sort of thing. But it's only an 8-incher, so it won't loosen your colon much. [ CHRISTINE R  May 25, 2014 ]
Maybe not sure [ MELVIN J  May 24, 2014 ]
I installed mine under the rear seat of my 2005 Jeep Wrangler TJ. Awesome perfect place super surround type sound [ PAUL  May 23, 2014 ]
It will not fit under the seat. The only place it will fit is in the trunk. I installed the B-8PTD in my Toyota xtra cab pick up behind the drivers seat. I installed a MTX RT8PT in the trunk of my FR-S because it is front firing and pointed directly at rear of back seat for better sound transfer. It fit nicely on right side of the trunk. I suggest adding sound deadening material to trunk and inside of rear fenders and trunk lid as there is none from the factory. [ RICHARD  Apr 12, 2014 ]
I wanted to put it underneath the front passenger seat of my 2002 Ford Explorer Sport Trac and it wouldn't fit. Ended up putting it underneath the rear passenger seat instead. [ ALEX  Apr 08, 2014 ]
I'm not a hundred percent sure but it should work even if you have to unbolt the seat [ MELVIN J  Apr 07, 2014 ]
It does have a small footprint but I installed mine in a Honda Ridgeline so I can't speak to your vehicle [ Michael  Apr 07, 2014 ]
not sure but have bought and used in 4 vehicles. it fits my sisters toyota corolla perfectly [ KENNETH M  Apr 07, 2014 ]
Yeah it fits [ JUAN  Apr 07, 2014 ]
Fits under my WRX 2012 Limited Hatchback with the driver's seat lowered as much as possible. [ TOMASZ  Apr 07, 2014 ]
It probably would. But the output sucks on it. Extremely jealous of your frs though [ DIEGO X  Apr 07, 2014 ]

Fit under the passenger seat of my RAM 1500. [ Jon  Jan 19, 2016 ]
Hello Michael, I'm not any help on this one, although I own 2 Toyota trucks neither is a Tundra. The B-8PTD sounds great behind the drivers seat in my 94 compact extra cab truck. Good Luck. [ RICHARD  Mar 07, 2014 ]
I'll I can say is it fit great in my 2010 Ford F-150 regular cab [ TIM  Mar 07, 2014 ]
I only bought one - so I do not know. They work best under the seats - doesn't work too good exposed, even behind a short cab pickup. Honest - if you can fit larger/more specialized components, you'd be better off. Hope this helps. [ JOHN J  Jan 19, 2014 ]
i hooked Sound Ordnance B-8PTD power to the battery, and audio to my receiver. Also connected a Sound Ordnance volume control in front of the driver seat. [ AURELIJE  Jan 19, 2014 ]
i don't know i didn't install it , i paid some one to install it. so sorry i couldn't help it didn't cost much only 100.00 for the hook up and wires. [ M  Jan 19, 2014 ]
I did not hook two of these together. One is sufficient for what I needed. Not sure how this would be done. [ RUSSELL G  Jan 19, 2014 ]
I can't answer that, I only put one in which is more than enough for a small truck, I imagine that putting two in is just like doing one but just hooking up two to the same terminals, such as the battery and the back of the stereo. This unit is nice because it fit right under the passenger seat, out of sight. [ ALLEN  Jan 19, 2014 ]
Hello Barry, I installed the Sound Ordnance B-8PTD behind the seat in my Toyota pick-up and it sounds great, but I did Install a MTX RT8PT in the trunk of my Scion FR-S and I am very pleased with it. It provides good bass without disturbing the neighbors. I hope this has been helpful. Rich [ RICHARD  Jan 19, 2014 ]
Barry, I installed mine in my 2000 Ford f250 under the rear seat, the other day my step son cranked it up and was vibrating the mirrors? So, I guess it works great - so I was told :). I'm very happy with the performance. Hope this helps [ RANDY  Jan 17, 2014 ]
Thanks, you think it is worth installing in the trunk at all? [ Barry  Jan 17, 2014 ]
Hey Barry. I installed one in the trunk of a 2005 Cavalier and also have one in my car (under the seat). I don't believe it fucntions as well in the trunk as it does under the seat. [ darrenh  Jan 17, 2014 ]

No; mine was installed in a 2009 Ford Focus SES without nav. Sorry I can't address a Prius install, but mine went smoothly and the sub worked well while I had the car. [ CHRISTINE R  Jan 06, 2014 ]
it don't matter about the vehicle of what type of radio you have it would hook up to any system [ MELVIN J  Jan 05, 2014 ]
Not sure, but I have it installed in a corvette with a Kenwood deck. I like the performance of the system as a whole. It does every thing that I was looking for in getting a nice bass with the Bose door speakers. [ MARSHALL  Jan 03, 2014 ]
Agree with Robert on the crossover setting; found that clarity improved by setting the sub's output to a rather low value. Still gave good extension to the low bass while avoiding muddiness and boom. [ CHRISTINE R  Jan 06, 2014 ]
I set everything at about 80hz and let the sub handle everything below that. I am able to control almost everything from the Radio. The only time I find the sub a little annoying is when the D.J. is talking. I must say I love this product. The overall sound is very full and complete. [ ROBERT  Dec 26, 2013 ]

The short answer is that I dunno. I had it professionally installed and they set all the switches in the back. I have no idea if it is optimal. Sorry for the useless answer!

I glued 12 small wood screws to the bottom like carpet spikes. I have the sub sitting on the carpet of the transmission "hump" under the dash. It is heavy enough that it doesn't move. Sound is great - even in exposed location. [ T BRENT  Aug 16, 2014 ]
You're missing something. It also comes with two tabs. About 3 or 4 inches long that have 3 screw holes. They fit on either end of the unit and you insert the supplied screws. depending on where you mount it and your application, you may or may not need these mounting clips. If you mount it in an open air type environment I suggest using them in the event of an accident you don't want this thing flying through your vehicle. Under the seat just use some Velcro to prevent it from sliding around. If you install it in a HP car, I suggest using the mounting clips no matter where you mount it. [ Marion  Apr 08, 2014 ]
That is correct. Just lies on the carpet. [ LEONARD  Dec 26, 2013 ]
The mounting is Velcro. I didn't mount mine under the seat so i drilled holes in the 4-corners of the base and used screws. [ DAVID  Dec 25, 2013 ]
Correct - I mount it that way. Using only the velcro strips. I cut the strip in half with scissors and use it on 2 opposite sides. If you want more velcro so you cover all 4 sides, just hit up Home Depot or Lowes for more. It really is a nice way to mount because its super easy to remove and reposition without drilling holes or anything messy. [ Garth  Dec 24, 2013 ]
Yes, attach the strips to the bottom of the unit then stick to the carpet! It's not my 1st choice for mounting an amp but it works just fine, plus I didn't really want to drill holes in my floor anyway! Good luck! [ THOMAS M.  Dec 23, 2013 ]
That's it. In my case I am using it in an RV and it is not secured to anything. It lays on carpeted floor under a seat. [ RICK  Dec 23, 2013 ]
Mine didn't come with any velcro, i strapped it down with some black fabric strap from an hvac supply house. But velcro from a hobby shop would work fine i think [ MICHAEL L  Dec 23, 2013 ]
Not sure. I haven't had a chance to try and mount it yet. I have a Jeep Wrangler and will try to mount it under the seat . [ BILL  Dec 23, 2013 ]
Yes it can be done. Shawn R W answers are on point. [ Garth  Dec 24, 2013 ]
Not sure what you mean, "linked together in one vehicle?" If you're referring to using this low-profile sub with a good line out converter and a stock (and probably aftermarket) head unit, the answer is yes. Be sure to get a good line-out converter if you're using the stock head unit. I ran mine from a Chrysler MyGig, HDD, NAV unit. Line Out converter and no amp. Sounded great. This sub has a small bass control knob that can be mounted just under dash above right knee. Plenty of clearance. Looks good. Be sure to read instructions (there's an online video too) on how to adjust bass output. [ MARK  Dec 17, 2013 ]
I saw this done on a F-150 Supercrew, the RCA output was split at the rear of the truck. Make sure you run a power wire and a ground wire that can support running two amps. [ SHAWN R  Dec 17, 2013 ]
I'm showing that this unit should come with the wired remote. If you did not receive yours and/or something has happened to it, then please contact our Tech Support team. They may be able to help you get a replacement. [ Jeff  Dec 07, 2013 ]  Staff
yes [ MELVIN J  Dec 07, 2013 ]
Yes Chris, this powered sub has speaker-level inputs. You can install it a couple different ways, depending on your preference or ease of access to wires. It comes with everything you need to install it except speaker wire. The lead they give you is short, so you'll probably need some. You can run it off of either the front or rear speaker lines or one of each if you want, front left & right rear or vice-versa. Your basically just tapping into it to get a feed to your sub so if you use both front or both rear it's going to work with your fader to fade the sub. If you have kiddos that would be in the back put both rear leads, so that if they need it quiet you can fade to the front & it'll turn the sub down without having to lower total volume or use the bass control knob. [ TODD M  Dec 06, 2013 ]
Yes, I kept my factory radio and used the input speaker harness that is included with the equipment. You will need to splice onto the positive and negative speaker wires connected to one left and one right speaker. I used my two rear speakers. But you can use the front speakers if they are easier to get too, but I doubt they will be. [ JOSHUA  Dec 04, 2013 ]
I believe so. Just wire this speaker in line with your rear speakers. [ RALPH  Dec 04, 2013 ]
you can order an rca splitter. it has one male connection and 2 females(radio shack sells them). you can run the sub off one of the female connections. i assume this is what you meant? that your radio only has 2 sets of rca connections not 3 for the sub. its not ideal, but it does work. with the sub it has the dial you can control output with. works well. not for hip hop or booming bass but works well for rock music. [ KENNETH M  Dec 04, 2013 ]
Dont know have an aftermarket stereo [ JUAN  Dec 04, 2013 ]
You should be able to. [ BRAD  Dec 04, 2013 ]
No. You need a line level (RCA) source for this particular sub. [ DAVID  Dec 04, 2013 ]
