I have a dual XIA3145 580 watt amp that keeps blowing the 2 20a fuses located on the amp. I've checked all my wiring for shorts. I came up with nothing my wiring is fine. The fuses blow about 2 seconds after receiving power no music is even played through it. So is my amp toast or is there a solution for this?
Generally, this indicates that there's at least one shorted output transistor.
Disconnect all speaker wires from the 'amplifier's speaker terminals' and disconnect RCA/signal cables from the amp. If it powers up normally, the speakers/wiring need to be checked. If it still blows the fuses, the amp almost certainly has shorted output transistors and will need to be repaired.
I'd recommend using two 10 amp fuses. The amp will power up with 10 amp fuses if there is no problem. If there is a problem, there's less of a chance of doing more damage by using the 10 amp fuses.
