Forget about tracing the power wires from the battery. If it is the fuse in the amp then the problem is the amp is blown, shorted, or overloaded.
Could be.Yet, There could still be an Exposed poss wire grounding out/Strands grounding out causing fuses to blow,even if you disconnect the speaker wiring,and RCAs using the Same Power/ground /remote wiring?Id check the wiring FIRST.If it continues,My LAST Testing would be to take the amp to the battery with Test wiring,of Power/Remote to poss, and Neg to Neg,.If Fuse blows? Its the Amp,If it works Fine,you have an issue with your wiring
then the amp has an internal failure. usually a MOSFET that has shorted. usually fixable.
NOPE. He already said it is the fuse BUILT INTO THE AMP that is blowing. No way anything between battery and amp power terminals is going to blow the built-in fuse. Either the amp has an *internal* short, or it is overloaded (shorted load). Like k_h_a said, probably a blown mosfet in internal power supply or output drive section.
