oh, well that sucks.... so how would a 15 avalance work with just 400 watts, compared to the 800 i wanted to give it?.....or should i just sell my amp and get a different one?
I would suggest that you get another amp, and use your four channel to power speakers in the car.
unless of course you can set your amp to mono, in which case you will be able to do it.
just as long as both channels are putting out the exact same signal and not in stereo, then you should be able to do it no problem. a lot of ppl power their DVC subs with an amp to each voice coil. but they have to make sure the gains on both amps are the same. So as long as its not in stereo it should be fine
