I have a Pyle PLMRA420 1000w marine amp. It's practically brand new.I have never abused it or overloaded it. Even with all the RCA cables removed and speaker wires removed it's permanently in "protect" mode... I've changed the fuse and also tested the power source for 12v... it all checks out...
Any ideas on what I can fix on this thing to make it work again?
