What customers say about "Size & Weight"
Alpine SWR-T12 12-Inch 1800 Watt 4 Ohm Shallow Mount Subwoofer
  • For a thin single 12 inch sub I'm extremely happy with the performance.
  • Awesome sub! Fit right under my backseat of my tundra. Excellent size!
  • Very versatile sub. Fits in a box underneath the back seat in my truck.
  • The sub sounds AMAZING, and more importantly it freed more alot of room in the trunk. This sub in the right box will not let you down.
  • Good compact bass. a little pricey but when you lack space and need bass its worth it.
JL Audio 13TW5V2-4 13.5" 4-Ohm 600W Shallow Mount Car Subwoofer
  • Upon unboxing, It's quite impressive to see a speaker with so much cone area with so little depth when you're used to seeing traditional subs.
  • Fantastic! They hit the lows you would expect from a good woofer. Fit behind the seat of my 2002 tacoma 4 door.
  • Love the size and the ability of fitted into small space and the performance sound of them is awesome, love the way that fit on my 04 GMC Canyon.
  • I have a small sedan and the fact that i could fit it in a custom box under the seat shows how easily you can fit this slim sub anywhere.
  • Simple, good looking, good sounding subwoofer that requires little space and very shallow = flexibility of installation and saves the trunk.

What customers say about "Audio"
Alpine SWR-T12 12-Inch 1800 Watt 4 Ohm Shallow Mount Subwoofer
  • Wasn't really expecting a lot. Very pleasantly surprised. Super clean and very loud.
  • I wouldn’t say it s value for money as they are expensive but excellent sound and quality and can for in 150mm of space. Very good bass.
  • We bought kickers last year and they didn't even last a hole year So we decided to go with Alpine they sound great look great we love them.
  • This sub is actually better than the JL audio 13.5" TW5. For me to say that is something as I am a huge JL fan.
  • All around clean bass. Low deep bass. And tight an crisp. Not cheap. But they are amazing!
JL Audio 13TW5V2-4 13.5" 4-Ohm 600W Shallow Mount Car Subwoofer
  • The end result is fantastic. Super smooth drum hits and deep, rich lows.
  • I was worried that it wouldn't work as well as the dual JBL 12" box I was used to. I was wrong. It has similar output and better clarity.
  • This is a very accurate sounding and musical sub - not boomy at all, but it does create lots and lots of bass.
  • I have been using this sub for about 18 months now - great bass sound quality from a tight space, just as advertised and claimed.
  • If you only have space for one sub, you want the highest power handling per sub, and the low frequency response then this is the one to get.

What customers say about "Features"
Alpine SWR-T12 12-Inch 1800 Watt 4 Ohm Shallow Mount Subwoofer
  • Very impressive shallow mount subwoofer. I am NOT a fan of alpine subs normally. This driver is however a cut above the other subs Alpine offers
  • Now installed with no fit ment issues at all, this sub is capable of vibrating the windows and mirrors and will handle more volume and power than I can!
  • The frame is strong. The thin foam seal seems to work well. All in all i am very happy!
  • Plastic that hold the wires to the voice coil breaks. I have had 2 sets of these and they all broke
  • The only quibble I have with this sub is that the aluminum surface dents easily so handle with care.
JL Audio 13TW5V2-4 13.5" 4-Ohm 600W Shallow Mount Car Subwoofer
  • The materials seem to be good quality and should last a long time.
  • It is a good speaker for the money; sound is clear and quality materials used.
  • It looks nice and the material seems durable. Can't wait to get it in the car.
  • For the price, this speaker is amazing. Sturdy construction and simple design makes this a great option if your looking to replace stock sub
  • Decent build quality and quite pretty design, bass is more than enough.
What customers say about "Connectivity"
Alpine SWR-T12 12-Inch 1800 Watt 4 Ohm Shallow Mount Subwoofer
  • This sub paired with the alpine 6x8 two ways in four doors and alpine tweeters in the front. All run off the alpine 5 channel v9.
  • I matched it with an Alpine PDX-5 amp on the sub channel, it has plenty of power!
  • It really sounds amazing I paired it with the Alpine mrx-m110 mono amp.
  • I just got a pair of these installed in my 06 Ford F250 in a custom sealed box with poly-fil and hooked up to a Pioneer GM-D9601 amp, which I also bought on Amazon, and they sound AMAZING!!!
  • It is paired with a Boss Riot amp and I could not be happier. Highly recommend if you have small space constraints.
JL Audio 13TW5V2-4 13.5" 4-Ohm 600W Shallow Mount Car Subwoofer
  • I hooked up this sub in a box I already had. Connecting the sub was fairly easy.
  • Connected this to an amplifier and my car is a mini disco hall, highly recommended!
  • Installation and connection was successful, it works as advertised, the quality is excellent!
  • Not sure whether I got a bad apple but the speaker died after a month. The connections points are flimsy too.
  • For some reason one of the connections on the speaker came lose. Also it has stopped working.
