I have two of these subs and they pound hard! Mine arent even being powered by the proper amp and they pound very hard cant wait until i get a proper mono amp. I would recommend these subs. Alpine is an extremely good brand. Very good quality.

I brought 4 and put them in a sealed box, sounds good real low bass. If you are looking for good woofers look no more. Alpine is top of the line and have been making good car audio since N.W.A and before! So who you with.

I've had this same sub going strong for a good 2 years now it was in my car for a year and now its in my dads truck in a 2.0 cubic foot ported box tuned to 34 hz and it hits pretty hard and sounds amazing in my dads truck....i myself have the alpine type R 12 in a 2.3 cubic foot ported box tuned to 32hz and i love it! it's been living for a year now lol.....if you're looking for a good sq/spl sub that will last long either of these subs would be a good choice cuz you can't go wrong with /////ALPINE.......and i ALWAYS let my alpine subs break in for about a month or so before i start pounding them real real hard everyday so they will live longer and sound better down the road
