I'm having some trouble with my amp... I have an ALpine 900x1 and a Rockford 900x 1 runnin to 2 12" HX2s.. However my fostage amps actin up, even when i have my power and ground wires unplugged, the RF lights up and the speakers still hit. But when i unplug the remote and speaker wire, the lights off and and the sub its runnin to still has movement but not as hard. The problem is, when i have the power and groung plugged in, it makes no difference and light only comes on when the bass hits. I also cant get my bass cube, hooked up to it, wont turn on either. I checked my ground and fuses, everything. The other amps fine, but i need help
