Rep Power: 294

I know my amp is cheap but it was free....im saving for a good one now but: Ive got a boss 180 x 4 ch going to 6.5 pioneers in the front and bridged to a 15" mtx 5500/5600 on the other channel. It will play fine, then the amp will blow a fuse, but if I disconnect the fronts leaving only the sub connected, then the fuse doesn't blow. Also it seems the bass cuts in and out sometimes but I think thats due to the amp being old and cheap. what do you think....

bad ground probably. A bad ground will cause a voltage drop, as the amp is forced to output more power, the voltage drop is going to cause it to draw more and more current to output the same amount of power

might just not be able to take of load of both try only useing speakers as subs usually need more power

probably bad impedence, check how wired and what your amp can handle per channel. if your impedance too low, too much current passing trew your amp
