yes, all the channels are working. my sub can only handle around 100 watts rms. and my amp is pushing 800 watts peak per channel. (accrdng to the manual). i dont have enough money to buy additional subs so i decided to hook up my old subs. its an alpine. i forgot the model.
my amp is dead. so maybe hooking up only one sub fried the amp. or something else cause it to die?
