This is a great subwoofer, I have mine in a slot ported box and it is really loud. No joke, this subwoofer is not for the faint of heart. If you want some seriously loud and CLEAN bass that can be heard blocks away get this subwoofer. I've owned mine for about two years now and it still is hitting really hard. With the name from kicker you know that you cant go wrong.

Great sub! Installed in back trunk of a Honda accord. I have mine boxed in a MEGA BASS box from a local retailer. I can literally hear the sub a few blocks away. I have it hooked up to a Kicker ZX750.1 amp. Very clean and nice sound. I would also recommend getting a amp for your stereo speakers.
