alright, the thing is, this is from my cambridge PC 5.1 system...
at my desk, it puts out an amazing amount of bass for its size. Im not bass crazy, im not going into competition, I just want some decent low end without taking up trunk space.

this thing is maybe 9"x6"x15", very small, just what I need. itll fit right behine my seat on the floor.

I got a pioneer and i think there is a feature for making the rear channels for sub sound only. so theoretically, if I bridge the two rear channels, then that gives me about 20 watts total to the little pecker. I dont think the system at home gives it much more.
