How to install a powered subwoofer
Learn how to install a powered sub and boost your bass
Powered subwoofers include all the elements of a subwoofer system — subwoofer, amplifier, and enclosure — in one convenient package. Here's a look at how you install a typical powered subwoofer.
Please note: As with any amplifier installation, you'll also need an amplifier wiring kit. The proper size of kit will be listed in the accessories for each powered subwoofer. If you need any help or just have questions about adding a powered subwoofer, contact our advisors.
How to install a powered subwoofer | Video Transcript
No matter what kind of music you love, adding bass makes it sound better. Let's take a look at what it takes to install a powered subwoofer in your vehicle with the help of one of our guys from tech support.
Find a place to mount your sub
Before you get started, find a suitable place in your vehicle to mount your sub. The sub’s built-in amplifier generates heat, so adequate ventilation is important. And you'll want to place it somewhere that's not too difficult to access.
Wiring kit and speaker wire
Your powered sub does not come with the necessary wiring, so be sure to purchase an amp wiring kit that includes the wiring and fuses you'll need.
Disconnect the battery
First, disconnect the negative battery terminal to protect you and your gear during installation.
Step #1: Running power wire
Next, run the power cable from the battery to the powered sub. Some kits have the fuse assembly already put together. But if not, cut a short piece of the power cable, enough to cover the distance from the battery to the fuse holder location, and strip the insulation off both ends. Crimp the terminal ring from your wiring kit to one end, and attach the fuse holder to the other end. Strip the insulation from the end of the wire that leads to your amp and attach it to the other end of your fuse holder. It’s important to keep the fuse close to the battery since the lead between the terminal and the fuse is unprotected.
In most vehicles, you can pass the power cable through the firewall that separates the engine compartment from the main cabin using an existing entry point. Once you're inside the cabin, tuck the power cable under trim panels or your carpet along one side of your vehicle until you reach your powered sub location.
Step #2: Running turn-on wire and signal cables
After running the power wire, the next thing to do is run the turn-on wire and signal cables. Both the turn-on wire and RCA signal cables need to be connected to your stereo. Run these cables behind the dash to your stereo. The turn-on wire connects to a remote turn-on wire in your stereo's wiring harness. It's usually blue, but confirm this with your owner's manual. Plug the RCA cables into the appropriate RCA outputs on your stereo.
Run these wires, the turn-on wire, and the RCA cable, down the opposite side of the car from the power wire. This will prevent electrical noise from entering your system and spoiling your music.
All of this assumes you have an aftermarket stereo with preamp outputs. If you have a factory stereo then you'll get the signal to your powered sub a different way. You’ll want to make sure your amp has speaker-level inputs and "signal sensing" turn-on capability. In this case, you can just tap into the speaker wires behind your stereo, or possibly the rear deck speakers. Either way, this will get signal to the powered sub’s built-in amp.
Step #3: Connect the ground wire
The third primary connection is the ground wire. This wire should be connected to the vehicle's chassis. Look for a nearby bolt that you can fasten the ground cable to. The ground wire terminal should be in contact with the vehicle's bare metal. Sand away any paint at the contact point for the best connection.
Step #4: Make your wiring connections
Now, mount your powered sub and make your connections. Try to use gentle curves with your wires and cables when possible to prevent unnecessary wear and tear.
Before you fire it up to test, turn the built-in amp's gains all the way down. And reconnect your vehicle's negative battery terminal. Verify that the sub turns on when you start the car. Then you can play some music and set your gains.
If you have any questions about powered subs, please give Crutchfield a call.

Hello, To connect an active subwoofer like polk psw 10 to a laptop and active bookshelf speakers like edifier r1280t, would 2 rca splitters (1 female 2 males ) and 1 rca-3.5 splitter work? Female end of 1 rca splitter attached to left male end of rca-3.5 splitter and the other rca splitter female connected to right male end of rca-3.5 splitter generating 4 male rca inputs, 2 left 2 right. Then 3.5 connected to laptop and 1 left rca input and 1 right rca input connected each to sub and shelf?

I currently have a Kicker Hideaway installed underneath the front passenger seat. I am mostly, about 90% satisfied with the sound output. But I'd like for it to be a little louder/deeper. Would relocating it into the trunk improve or increase its volume?

Hi, I have a 2006 Subaru Impreza, 2.0 I HATCH MAN, station wagon. I was looking for a subwoofer to buy for it because it has holes in the back above the rear wheels where subwoofers can be installed, I also have a pioneer stereo which will allow for subwoofers to be plugged in, just wondering which subwoofer you think would be best and which one might fit?, Thank you :)

I have a jl 600/6 powering 6 jl speakers. I just purchased a jl active box along with an rca splitter. I have the rca cables split from behind the deck. My active box has no sound when wired to rca. The only way I can get the sub to work is if I take speaker wire from the amp to the active box. I verified the rca input on the active box is working by hooking it up to another car. Why can't I get my active box to work off of rca cables?

Hey guys, I bought a powered sub B8-BPDT?, from you guys a couple of weeks ago. It has two RCA inputs left and right. My Boss 660 head unit has 2 channels RCA outputs. Can I use one channel out for right input and the other channel for my left input? Or do I need to get an RCA splitter to use for one channel out to right and left? Just need to know because I'm a Disabled Veteran and can't really get into too many positions installing this, it takes too much out of me. Thanks

I have a 2003 Nissan 350z and running the Kenwood DDX394-SAT 4 speakers and the prewired cable for the vehicle I purchased back in 2017. I have purchased JBL GT-BassPRO 12Powered Subpass Subwoofer. My problem is I purchased the EXF Amp Wiring kit 10 gauge I show power 12v at the SUB and ground back in the hatchback at the ground for the interior light so it should be good. (My question is do I need to run a control cable back to the amp if so I am not sure where on the wiring kit to connect.) I show no power light at the led on the back of the JBL - could the power line coming from the battery be the issue? Could you give me some direction. My daughter is going back to school in Tennessee and was trying to get this workingin time. Thank you for your assistance.

HI, I wish to add a Pioneer TS-WX130DA 8" underseat subs to my 2008 toyota corolla, Ascent sedan. The pioneer sub does have speaker input capability, but does not have 'speaker sensing turn on cap' based on the specification. How can I wire it to the toyota original head unit for turn on and turn off? And if I would tap the signal from the head unit, which peaker output- front/ rear should i tap the signal cable to?

Hey i have a quick question, I have a blaupaunkt 200 W 8" active subwoofer encloser, and i want to add a few tweeters. Assume i know nothing about power/wiring (which i dont lol.) What wattage tweeters would be the best choice with this, do i need to find a pair of tweeters that match the power of the enclosure (200 watt woofer /200 watt tweeters) or would i need to add another amplifier to supply the extra power, lets say a 600 W amplifier for said 200 W tweeters?

I bought an Alpine PWE-S8 for my 2-door '15 JK, with an aftermarket Joying headunit with a single RCA sub output. It also has RCA outputs RR RL FR and FL. The sub is located in the rear cargo bin. I believe the Alpine can pick up signal over RCA with "sp-in" so I'm running one of the leads to the sub output. I've run a dedicated power, tapped ground, yet when I turn the ignition, the sub does not turn on. The amp kit I purchased has a separate fuse, but I don't think it's necessary... Taking the voltage tester to make sure my leads and wires all have power. Any other ideas on troubleshooting this?

If I buy 2 powered subs and a set of front components. Would it be better to buy a 4 channel amp, run the components from 2 channels, then use the line out from the other 2 channels to connect to the powered subs? Or just buy a 2 channel for the components and keep the powered subs separate? Thanks

I just had a JL microsub+ installed into an 04 town car. Its connected to a recently purchased kenwood excelon DNX695S . to say that im not impressed with the bass is an understatement. At lower volumes bass is just ok when you turn radio up nass doesnt seem tp get louder. With that being said. With the 2 adjustments on the built in amp os there an adjustment i can make to make this sub hit harder. Ive read reviews where people say this 2 wooofer sounds betyer than 2. I find that hard to believe. I dont expect it to win any competitions but i would hope i can get my drivers seat to vibrate some. Any help would be greatly appreciated.

Chris, You can probably wire the inputs either way, but using both left/right inputs for both subs may work better. Unfortunately for you, you'll have to use two controllers for your two subs.

Or parallel them together as stereo to both the left and right (using speaker-level inputs, not RCA). Also, is there a way to use just one of the controller modules to adjust the gains on both?

I've scrolled through the above comments and didn't see this question, but I'm sorry if it's a duplicate ... Is it feasibly possible to connect a powered sub/amp to an alternate source of power besides the battery, perhaps a fuse box or similar? I'd like to avoid tapping the battery directly if possible.

Anthony, Your factory radio won't power the sub, its onboard amplifier will do that. The FAST kit is made for exactly the application you want, connecting the sub's input to the factory speaker wiring.

I recently sold my 96 Blazer that I had originally purchased a Bazooka BTA850FH for. With the Blazer I had an aftermarket head unit with RCA outputs already so the hookup went smooth and easy. I now have a 2014 Ford Focus SE, and am curious the power output of the stock radio, and whether or not it'll be enough to power the sub. I've done countless hours of research online to find an answer with no luck. The sub has been sitting disconnect for months now. Before I buy the F.A.S.T kit again I would like to know if the stock radio can support it, not looking to upgrade the headunit or any other factor of the system since it performs very well. Any feedback is greatly appreciated.

Joshua, The auto turn-on mode of that powered sub works when using the high-level inputs. For those, you don't need any "splitters." You tap the factory speaker wiring to get your sub's input signal.

I have that jbl powered sub. Does it need a turn on wire? I thought it had an automatic on/off function. Also on my 2010 Mazda 3, instead of getting new head unit I saw that you can use aux splitters and "RCA to aux" splitters to get the sub to match the music. Do you suggest this or should I just get an aftermarket head unit instead?

Paul, A great way to get a remote turn-on voltage for your amp is by using an Add A Fuse to add a fused circuit to your vehicle's fusebox. First find what style of fuse your vehicle uses - ATC, ATM, or ATMLPDT - and get the appropriate connector and a 2A to 10A fuse. Use the factory radio's fuse to add your circuit to.

Ratnadeep, That sounds like a perfectly valid way to hook things up. In fact, my vehicle is set up the same way, with the radio's fade control functioning as a subwoofer level control. If there's something about your system that doesn't sound right, you should take it up with your installer.

I have installed a powered 8" subwoofer tube to my car Hyundai Eon's factory fitted music along with 6.5" JBL components in the front door. I have factory fitted 5" speaker's on the rear. The technician who installed the woofer and front speakers did the following. He attached all the speaker's to one output from my stereo and another output to the woofer he said he did the same because my stereo does not have separate sub woofer out. Now when I turn the fadder controls on my stereo to one side my speaker's only work and when turned on the other side only woofer works. Pl. Advice whether this is correct and is some another way to get the maximum out of my music system.

Melvin, Those powered subs each come with its own power cable and in-line fuse. You'll need to run both of them to the battery. An alternative method would be to run 8-gauge power wire with a 60-amp in-line fuse from the battery to a distribution block. From there you'd use the subs' power cable to get power to each sub. For input, use RCA Y-cords to supply the same signal to both subs.

Chase, In car audio, one has to make compromises as to which position of a subwoofer sounds best in your vehicle and which position the subwoofer can actually fit into without interfering with the driver or passengers' legroom. Like Stephen says in the video, "Find a suitable place in your vehicle to mount your sub. The sub's built-in amplifier generates heat, so adequate ventilation is important. And you'll want to place it somewhere that's not too difficult to access."

Gary, You can get the input signals for your powered subwoofer by tapping into the factory speaker wiring either behind the receiver at the wiring harness, or at a more convenient spot like your vehicle's rear speaker wiring. Great connectors to use would be Posi-Tap connectors, so you won't have to crimp or solder wires together.

Donnie, The sound of a subwoofer in a vehicle changes depending on position, aim, and proximity to seats and walls. The only way to find which is the best location for a subwoofer is to experiment, trying different places and positions.

Joe, You can get a receiver with front, rear, and subwoofer RCA outputs, or get one with less and use RCA Y-cord adapters in order to get signal to your amps. I'll bet that 600W number attached to a 4-channel amp is a peak spec and worthless for planning an amp installation. But even at those numbers, I doubt you'll come upon any power supply issues with your amplifiers.

Can I run a 150W powered sub and 600W 4 channel amplifier on the same system? I'm concerned about power issues. Also, I plan on changing the head unit. Do I need to look for one that has extra RCA outputs, or can I use an RCA splitter?

Luis, You'll need a 10-gauge amp power wiring kit and some speaker wire. You connect the power wiring between the car battery and the powered sub. Ground wire goes from sub to chassis. And you'll use speaker wires to get the sub's input signals by tapping the car's rear seat side panel speaker wiring. Why don't you give us a call so an Advisor can help you get everything you need. Plus, if you buy from Crutchfield, you get free lifetime tech support for your gear.

Any advice will be appreciated... Thanks.. Luis, Gainesville VA.

Pete, A fuse is absolutely necessary in order to protect you and your vehicle from burning up in the event of a short circuit. It goes on the positive battery lead near the battery. Ground wires usually connect to the vehicle's chassis, not to the battery.

Is the fuse holder necessary to hook up the sub to the battery, or can you just secure the power cord directly to the negative terminal?

I am trying to install a kenwood ksc-sw1 to a new head unit, it used to be connected to the factory head unit via an IEC AULOC line convertor because there were no RCA inputs to the old head unit. I have tried plugging the RCA cords into both the line convertor and the head unit directly but get a strange distorted crackling sound coming from the speaker. Any idea what could be causing this and how to rectify it?

When utilizing speaker level inputs, do I need to tap into both left and right inputs, or will one input provide all the signal I need ?

Sekhar, yes, you'll still need to run a dedicated power cable to your vehicle's battery. Sub's are power-hungry by nature and you won't get the full performance of your powered sub without the proper wiring.

Is it necessary to get a dedicated cable from the battery (fuse box) to power an under seat sub woofer? Can't I just connect the wire to the one that's supplying power to my head unit? In my case, the head unit is a new model Pioneer DEH-X3990BT and the sub is a Blaupunkt XLF 200A.

I've had my MTX powered sub for many years and it recently started blowing fuses. Each time I replace a fuse and reconnect the battery the fuse on the sub blows; is there a logical reason why.

Dan, no, you don't need to add a line-out converter. Your sub's speaker level input takes care of that for you. Posi-Products speaker connectors will be the best tool for the job of tapping into your rear speakers signal.

Scott, it can be done. If you're currently using 10-gauge power and ground wires, it would be safest (and give better performance) to upgrade to 8-gauge, then use a distribution block to connect the power leads from each sub. Likewise for the ground. Or, you can run a second set of wires for the second powered sub. The audio input will be a little tricky, unless one of the powered subs happens to have an audio output. If you're using an RCA cable from the headunit, you'll have to use an RCA splitter to branch off to the new sub. Or you can just use the speaker-level inputs and tap into a speaker line.

David, that should work, but be sure to check your powered sub's manual to make sure that you actually do need to tap into the turn-on signal. Many powered subs will power on when they simply receive an audio signal.

I've got a 1999 BMW E36 328ic Convertible & am thinking of adding a powered subwoofer in the trunk. If I know the "pin-outs" on the connector going into the Stock Amp coming from the stock head unit, can I "splice" into those wires for the "Turn-On Signal" & Sub-Signal Inputs Left/Right?

Les, there's definitely a fuse holder on that power line. It came pre-installed on the power cable. It's just a little further down the line and out of the camera shot. The kit I used was an older version of this 10-gauge kit from EFX.

Virgil, a powered sub by design has its own amplifier built into the box. You don't need to connect it to your other amplifier. You simply need to run power from the battery. Enjoy!

Thank you for your time and expertise. I have a PPI 900.4 amp. running 2-Infinity PR6502is and 2-Infinity PR9603is. I just purchased the Rockville RW10CW 10" slim subwoofer. My question is, can I running my powered sub from my amp or do I need to running its own power to he battery? I know it should not be a problem, but I am looking for your professional opinion.

Hello, I am wanting to install 2 pioneer active preloaded subs in my pickup under the rear seat and not sure how to do it. Will I have to run a power wire and remote to each sub or can it be ran consecutively somehow, and should I run the speaker signal from the side the subs are on(ie: passenger side signal to passenger side sub etc). I would really appreciate your help. I've been racking my brain on how this needs to be done right.
