Subwoofer to fit under my passenger seat

Anonymous	Posted on Tuesday, October 14, 2003 - 03:06 GMT Is there any sub out there that can fit under my passenger side seat? I can hook it up to my kenwood amp(Kac 7201) or even possibly upgrade my amp so its able to push 3 subs...Id like to shake the heck out of the person next to me...
