So i cant decide what to do. I have a nice 12" sub that my sub amp died. i also have a small 2 channel amp (40x2) but its too small to power my sub. What would you guys do? get another sub amp (which id need like a 500+ watt amp or get a nice set of 6x9s and run 3 sets of speakers? You think the 6x9s would have a problem with the sub running and pushing on the 6x9s?
