Alpine PWE-S8

Can I use this under passenger seat in a 1971 BMW 2002?

Once you have pulled signal from your OEM system, and connected the powered sub to your battery and ground. IT will work just fine! :)

It's been a while but it should fit under the seat you just have to be careful that the cables on the older cars aren't in the way which may prevent you from moving the seat forward and backwards easilyEnter an answer to this question.

Depends on how Much room you have under the seat you need 4-6 inches for clearance I have mine under my drivers seat but it adjustable

I put the sub I purchased in a Santa Fe. Not a 100% sure about the Ram but if you can reach under the seat and don't feel or see any obstructions you should be fine. Make sure when you install it there are no wire harnesses or brake lines under the carpet or under the cab that a screw may catch. Good luck

[ MARTIN Dec 07, 2021 ]

[ Charlie Dec 07, 2021 ]

Yes, it should fit under any seat you choose. I loved mine while it worked. It lasted just over a year before it stopped working. I never adjusted over half way on sub and had everything adjusted in my Sony head unit. I personally would choose another brand based on my experience.

Under the left passenger seat would be best.

If i hooked this up to sub output on deck can i leave bass control knob unplugged and adjust bass through the deck?

This is an 8" shallow mount sub, as noted in the item number PWE-S8 (Powered Woofer Enclosure Sub 8). IN order to ensure it will fit under your seat, it is always best to measure before you order. Not all cars have the same useable space under the seats, so it is up to ou to be 100% sure. Also be sure to add the amp installation kit when placing your order. Power, Ground, RCA, and Remote turn on wires along with an inline fuse holder.

[ ABEL Nov 17, 2020 ]

[ STEVE Aug 29, 2020 ]

What wiring accessories are needed to connect to boss head unit?

It requires RCA inputs, so you would need a speaker out to RCA adapter or converter if your stock radio has not RCA outputs.

[ SCOTT MICHAEL Jul 26, 2020 ]

I have a power wire ran to my 4 channel amp that powers my speakers. Would I have to run a second power wire from the battery to power this sub/amp?

I installed a Kenwood ILX 650 head unit. The sub plugs directly into the rca outputs from the head.

[ DAVID WAYNE Jul 26, 2020 ]

[ CASEY Jun 25, 2020 ]

If I mount in the trunk of my vehicle under the deck lid facing downwards, will the base reach the interior of the vehicle?

If you think the power wire can handle it, you may be able to get away with adding a power block first and then a shorter wire to each amp.

[ JUAN P Jul 04, 2020 ]

Yes that's what I had to do for the 1997 Jaguar XK8. The power must come directly from the battery but the on off power is wired to the main amp that separately powers the 4 channels.

[ MARK A Jul 03, 2020 ]

[ Justin May 18, 2020 ]

How many amps exactly, would the whole unit draw from the cars battery? I'm afraid my cars charging system can't handle the strain of anything attached to it.

It will, not the best location but I installed this in the hatch area in a CRV and it was plenty loud

[ johnny May 18, 2020 ]

I wish I knew. I mounted mine on the floor under the bench seat of my single cab pickup. It is amazing but then again I'm not a 21 year old rapper. For my purpose it is fantastic.

[ BRIAN L May 18, 2020 ]

I am sure it will! It thumps good enough to where it makes the mirrors vibrate...granted, I turn my volume up high and I have it under my seat where it fits perfectly. I recommend you install it inside the vehicle vs in the trunk though. My 2 cents...

Does this have a crossover that will limit the frequency sent to the speakers? i.e. all frequency under say 150hz is handled by the sub then the upper frequencies sent to the speakers?

No it doesn't. Heavy duty Velcro works great to keep this secure (which I believe it comes with).

I can't answer for sure. I powered my speakers off of a separate AMP

[ Gary Mar 22, 2019 ]

I believe so. Wiring diagram shows wiring to all four speakers though. Also without leads for sub use only you'll have to adjust the gain manually.

[ ROBERT Mar 22, 2019 ]

Didn't consider trying that. All of the speakers are separate from the subwoofer.

[ PAUL A Mar 22, 2019 ]

I believe the answer is "no." I did not do the installation personally, but I studied the wiring harness & electrical connections. I think any direct connection to another set of speakers would be unconventional and not work.

[ Alan Mar 22, 2019 ]

Can you use two of these?

[ TIM Jan 01, 2019 ]

Can I purchase only the accessories that comes with this compact subwoofer?

I suppose you could, but it all depends on the wiring. Each one of these powered subs connects via a pair of RCA cables to a preamp output (and a multiple wire pigtail). And these low-profile subs are a compromise from the start. If I had a system in my car that was so serious that I wanted two subwoofers, I would not be looking at these little powered units. Hope that helps.

[ Alan Jan 09, 2019 ]

I think you can!

[ Carmen Jan 08, 2019 ]

If you are using RCA output, yes you could, you would have to run separate power to both. Would not recommend two if you are using speaker level outputs. You will need a splitter off deck RCA inputs, you will need 4 total.

You need to measure to be sure. It is very compact and puts out excellent bass for the small size. Fits nicely under driver seat of 2014 Nissan Armada.

[ ERIC Nov 15, 2018 ]

You'll never know until you measure. Height of unit is ~3". LxW dimensions are too large to fit between the anchor points of the seats in my Subaru Outback. BTW, I've been disappointed in the performance. I know it's small and just provides fill, but I thought it would have more kick. My previous powered sub did have that kick, but the sound was fuzzy, not tight.

[ Alan Nov 15, 2018 ]

you have to measure the space under the seat and compare it to the specifications of the unit. - might work better under one of the rear passenger seats

[ johnny Nov 15, 2018 ]

I haven't driven a Sienna in over five years. I would caution putting the sub under the driver seat. Especially if you have powered seat. Look for a better location and the sub will serve you well.

Maybe if your vehicle does not have power seats You may wanna consider under the rear seats

I purchased this sub to go under the seat of a 1973 Jeep CJ5. We had to use some small spacers, but, it fit beautifully and sounds awesome.

Does anyone have this in a Subaru hatch back? Anyone listen to death metal ? How's the double bass drum kicks? Also can it handle hip hop bass? I know it's not gonna rock the house. Just wanted to fill in the lows.

Based on all of the information I've been able to find on various Miata enthusiast sites, the 3rd gen Miatas don't have enough vertical clearance under the seats for an under-seat subwoofer. Most people mount them on the vertical wall behind the seats instead, at least in earlier Miatas (that's where I have the sub in my 1991).

[ Andrew Dec 07, 2017 ]

I'm afraid we don't have the area under the seats listed in the research for your 2011 Mazda Miata. However, when flat the Alpine PWE-S8 measures 13-1/2"(depth) x 9"(width) x 3"(height)--if you find there's sufficient room under your seats for a box with those dimensions, the Alpine would be a great option. For more details or to discuss further, please feel free to contact an Advisor directly by phone (888.955.6000) or online chat. Thanks!

[ DAVID Oct 11, 2017 ] Staff

I don't know much about the Miatas, but the measurements of the subwoofer are the w 9.5 inches L 13.5 inches and the height 2.75 inches. If this measurements are under the seat it will be a fit. Performance wise I do recommend it.

Installed mine in my gmc 2500 hd behind rear seat. I had to turn my sub settings on head unit to max for great results. I listen to all types of music. Also when I say great results, it's just a "comfortable" bass level. To really bring out low ends I would need two or something bigger.

It connects to the sub port on the head unit for signal and on-off, and to a 12-v source for power

It will connect directly to your head unit, provided you have the RED/WHITE output on your head unit. Since it is an amp, it won't connect to another amp.

I have seen this amp in a jeep magazine. It comes with a wire harness that is plug and play with a stock jeep radio. You unplug the current wire harness and plug in the amp harness then the current one plugs into the back of that. Do you have this harness?

I wired each one using a 4-gauge dual amplifier wiring kit and put the fuse block on my firewall. I ran two #10's to the fuse block and then ran a #4 to my battery.

Would this product fit under the back seat or front seat of a 2016 GMC Canyon? The Canyon has the Bose 6 speaker system. But, I want to upgrade the speakers to all Alpine with a subwoofer, if possible. Thank you for your advice.

I put mine under a 2005 Honda Accord Coupes seat. The only issue I had was in the length of the unit. I had a heating duct the pushed the unit back so that it extended past the bottom of the seat (just barely). I think the RAV's seat is a bit larger and sits up higher than the Accord's seat, so it should be fine. I would check under the passenger seat to see if there are any obstructions. I also had to place the unit inboard so that the seat adjuster cleared. I had plenty of clearance on the sides, so this was no problem.

[ MARK Jan 20, 2017 ]

I don't know. I don't have a RAV4. Try measuring the space under the seat and checking the dimensions.
