Nice

Just recieved mine today hooked em up to a kicker 400 watt amp which pounds the hell out of em. Really good sound. Crystal clear bass.

Alpine Rules Only

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.

Capable shallow mount sub

I have been a fan of Alpine head units and speakers for over a decade, although this is my first Alpine sub. I mounted it in a 1.0 cf box (recommended) and it hits hard and tight. You don't get the deep lows you would with a sub with a bigger magnet or more play but it works well for under the back seat of a crew cab truck. Not the sub you need if you are looking for window cracking bass but it enhances all types of music and will still set off car alarms. I am pleased with my purchase and will continue to purchase quality Alpine gear.

great subs

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.

last long!

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

Good SQ and SPL

I usually stay away from alpine because just like JL audio they're way over priced and just like JL audio they cant hold up to their claim vs cost and will blow up quick!
