Alpine  SWR-1522D

Best woofer ive ever owned. put in a custom ported box, no need for a/c. moves so much air!

This sub is pretty nice! It can take a beating. The same day i got it i gave it 2000 watts Rms. now of course i fried it 1ohm impedence and am now running it at 4ohms. but it still hits hard, turns heads, and sets off car alarms while only getting 600watts rms. im beatin out 2 12" kickers, infinity, and otha shit. but b4 u buy this, look at the amp u got and see if 2 12" type R's wuld better suit u. ckuz that set up wuld beat this 1 15" with the right amount of power.

This sub is awesome!!! I am running it through a 1600 watt hifonics amp at 1000rms It makes my friends 2 12" audiobauns look weak. This sub will make ur ears ring at low frequency's! With the right hook-up you will love this sub!

This thing freakin rocks my socks! I have this sub in a 3sqft. box tuned to 30Hz and I'm giving it 1000 watts at 2 ohms. Hold on! It will make your ears ring very easily. This sub is really power hungry. It dims the lights in a Deisel truck with two batterys. After I regrounded my alternator and both batterys and put in a cap the problem is solved. This 40lb. sub is the best bang for your buck!! My order was to my door for free in fine business days and I'm in Houston. Beat that!!

This is a great value! I have been in to car audio for 15 years and have own many scores of different high dollar subs looking for the best sound quality and low frequency performance. I love these subs and you will to. The kids who only care about the most SPL should buy JL13w7's or some other 50 pound beasts that sounds like crap, don't get me wrong these sub get load and can shake your whole car if thats your thing. I drive them at a 4ohm load with 2 Alpine PDX-1.1000 the more power you have on hand will give you better sound quality even if your listening at lower volumes. The 2.8cf ported boxs I built myself to fit nicely in to the trunk of my Lexus ls430. The subs fire to the rear with the ports entering the car by way of the rear deck. The bass is as cleans as I have heard from 15's. the only other subs I would buy are Clif Designs and Jlw6 can sound great but box design is much more important then for the alpines. Focal 3 ways are the VERY BEST fronts by the way.

I have this sub running off a kenwood 9104D mono amp and its perfect never misses a beat. Its A great way to spend your money if your lookin for loud clean bass.

I got two of these running off a hifonics 2600d class amp wired down to 1 ohm in a custom ported box built to specs. They get so loud you cant even breath. Deffinatley a good investment. WAY underrated too.. can easily run 1000 rms

I have one of these in my 2005 dodge neon and it hits its on a kenwood 1800 watt mono amp and it just bumps. i can get 151.2 dbs no problem.

holy crap i just hooked mine up to a 1800 watt kenwood.. I can hit 164 easy!!! this is a great sub!! it totally rocks my ass!!

I love this thing i had 1 Alpine MRP-M2000 2000W amp and 3 of these and really in a blazer they rock my cousin had 4 memphis m3 mojos 12" and they blew his outta the water love the bass

I have two of these bad boys and let me tell you bo.they are clean and pound hard just like when i am in the sack

i have one hooked up to a us amp its the shit a litte cone sond but it go's a way after a litte betting. but it not a bad subwoofer for the price...

I like the product but the Kevlar ripped I am having an awful time with online car stereo replacing it there is basically no warranty on any these products and if I was you I would but local

damn dude, i threw 1 of these in a t-cab box with 2000 watts and i be shaking buildings. one time i made a girl orgasm while i drove by a high school. she thanked me because she would never think she could jizz herself!

Okay, so unlike all the other 16 year old kids below me who say they have been in car audio for 15 some years and talk like the haven't gotten out of high school yet about this sub. I'm going to give it a fair review. Sub is by far no SQ champ. If SQ is your thing, defiantly stay away from the R. You could try a type X, their SQ is very pleasing. As far as SPL goes, I tested this sub in 2 different Boxes, a 3.8 ft^3 @ 35 Hz and a 3.6 ft^3 @ 30 Hz. For daily driving the 30Hz tuning made the sub very much enjoyable, and it got low and rang the ears. the 3.8 @ 35 Hz box did get noticeably louder, but I like low tuning, especially on subs that can get low. As a hip/hop daily listener, this single 15" in the box mentioned above would be more then enough to satisfy anybody. It metered in 144.7 dB SPL @ 33 hz in the 3.6 box, and 145.6 dB SPL @ 37 hz in the 3.8 box. Fairly impressive. The power handling is lightly skewed, as this sub can take 1500 RMS daily, assuming you are the average nimb-wit, turning the gain knob all the way up and bass boost maxed out. I'd recommend this product for daily hip/hop listeners who want a cheap and loud single 15. Just don't forget to get a custom box built for your sub, as the box enhances the sub, not the other way around. -Jensen G

I have 2 of these hucked up to a hifonics 2600d class amp it kicks ass at 156.6 db....

this sub is pretty tits it hits hard but i was expecting more thatn it can go i alwys make this thin flutter i only have a 1800 watt amp annd i thnk it can handle more

I drive a 1998 KIA Sportage. I have a Sony Xplod amp at 500 watts x1 RMS at 4 ohms. Was pounding with a Memphis Power Reference 15 single 4 ohm voice coil, that was pretty loud.But when I installed my new SWR-1522D I could not believe the difference. This sub is louder and cleaner than any I have ever owned or even heard before. For the money you cannot go wrong. Thank you Alpine!!!!!!

This thing is the mad note. I got 80 of these in my ford pinto wagon powered by an 80 channel 80,000 watt dual amp. This stuff is straight up kuztom. I blew my whole roof clean off. These things hit a lot harder than them old Vagmaster 3,000 12s and my Assblaster 9,000s.

Had a single one of these hooked up to a HiFonics 2000 watt amp @ 2 ohms and the bass was pretty good. Lasted me for around 2 and a half years and hit hard through all the time. Running it at 1300 RMS seemed to be out of its range and now the sub does not sound at all. Tried everything but sadly it is dead. Great sub while it lasted though.

i had 4 of these fifteens in my 98 sonoma , 156.9 db running 4, 2000 watt hifonics amps and in a 13.5 cubic foot box tuned at 38 hz it was ok loud i expected more and better sound quality but if you want loud sloppier bass this sub is for you it prevales @ hip hop, rap, rb you know bassier tunes good sub for the price if your spl
