i dunno if this is the right place,, but, i just bought a new amp and hooked it up, now when im playing my subwoofers my right woofer isnt hitting right on each beat, but its still moving, i pushed down on the sub and no crackling or any sort of sounds, and its pretty easy to push down on, so i didnt think it was blown, i have a mono amp, is it possible that only the - or + on the amp can crap out?
