I have american acoustics(us acoustics)...car amp which is I believe a 4 channel amp.
I don't see any bridging buttons to press as I'd like to use half the amp to power my sub.
Can some one tell me if I hook up one wire to the + on one channel and the other sub wire to the - on the other channel will the amp automatically bridge?
The amp has low and high level pass filters for both channels and of course I don't have the manual.
it should and itr should tell you what terminals to use. also make sure the sub is a single 4ohm or dual 2 ohm speaker. I most likely has to be no less then a 4ohm load on those channels bridged.
