I'm not a huge bass fan, myself.

For what it's worth, I'm satisfied (not happy, but satisfied) with the bass output of my system already. I am not, however, satisfied with the quality of the sound that it puts out, and I am not satisfied with the midrange frequency output of the speakers.

I've never seen a 5 channel amp, though...and I don't erally like the sounds of that tri-mode stuff....sounds to me like just mixing the left and right signals to the sub and using a common ground...sounds cheap and easy to break and not where I wanna go. Any other methods just need more money than I have right now...
