on of the best square sub, up there with kicker
These speakers sound great if you have it weighed right. If you wire it to 2 ohms they can blow easy, if you wire it to 4 ohms your good to go. I had these for 3 years and still running strong. They sound better that MTX jackhammers. If you get these speakers you have to know what you are doing and take care of them and they wont let you down. You wont be able to hear yourself think.

Amazing sub!
Okay, listen the two who gave this sub a bad review are RETARDS, I have two of these as well as it's baby brother the 10, which I own two of as well and they hit so hard my entire ford ranger rattles. Good price for SQUARE 12's. I have ran them wide open for about 3 months now and never broke them in with all that test tone crap, I don't care for it, but any how these things hit so hard when listening to a heavy bass song it feels like a massage. My jeans literally vibrate and blow around because of how bad the air vibrates in the cab, DO NOT WIRE TO 2 OHM!!!! If you buy these you have to know to hook to 4 ohm if not they will blow in no time, they only make a 4 ohm model for this amp so READ the specs before you wire it up!!

Horrible sub
DO not buy these subs. I looked at them and thought 12" square subs for cheap.... "not bad!". BOTH blew off my older alpine f707 within 20 mins. Super crappy sub.

Mb Quart square subwoofer
Hello, i had gotten this sub just to hold me over until i got a better setup. i looked into mb quart and they seemed like a nice brand. i hooked this up to my Alpine mrp-350. it puts out 350 watts rms at 2 ohms.. slightly lower then the subwoofer. So i wired the subwoofer to 2 ohms and hooked it up and having my gain at half and bass boost at three quarters. it blew within 10 minutes. i am sure this subwoofer is overrated however it did sound nice and hit hard when it was playing. Made from solid materials. just overrated.
