At home theater forums, pretty much any time that someone asks about a
good budget subwoofer, the Dayton 10" powered subwoofer from Parts
Express (

) is immediately suggested. This subwoofer is consistently praised for
sounding much better than its price would indicate. I have one myself
and it's great.

I'm looking for a car audio equivalent.

My Kenwood KAC-8401 is currently using 2 channels to power the front
speakers and I would like to bridge the other 2 channels for 1 180-watt
RMS channel (according to Kenwood specs) to power a subwoofer.

What subwoofer and what kind of box should I get? I don't want loud and
boomy. Tightness is very important to me.

Thanks for your help!
