Hello, I have a busted power sub(fried amp). I was hoping to power it through my receiver since I have 4 channels currently unused. I would just run it on 5 channel stereo. How would I do this. Could I use 2 channels(positive of channel one and negative of channel two)? Also, is there a way to bypass the amp while still using the crossover? Any help would be very appreciated. Thanks! slimnewbie
