I have 1/0 AWG running from battery to trunk, into a distribution block, two 4 AWG wires out, one running to each amp. 4 AWG ground from each amp, both grounded to the frame of my car. one remote turnon wire from my head unit to trunk, cut and spliced to run to both amps. rca from head unit to trunk, split and running to both amps. each amp is bridged running one sub. amps are Legacy LA2970BK. my problem is this: yesterday, everything worked. today, one amp works, but the other doesnt. it has power, the blue trim on top of the amp lights up, but no pwer to the sub and neither the power led OR the protection mode led light up. ive checked everything, all wires are good, changed the fuses, and now the other amp goes into protection mode randomly. im stumped.
