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.

Decent Subwoofer

The following review is for a previous version (SWS-1222D).

For the money you pay, its a great sub. I have one in my car and it pounds when it needs to. If you listen to rock its a bit soft but then again its a low budget subwoofer. Quality is great on it.
