Help needed: Sony Amp

[mugeneration]

so what speakers do you have coming off the amp? The front ones AND:

a) a sub OR
b) rear speakers

Whatever, if its only the front ones cutting out then itd be the RCAs, or the speaker wiring. Worst case scenario is that something is stuffed in your amp thats doing it.

im assuming its a slice in some of the insulation for your wiring somewhere along the way allowing for you wires to ground out the signal.
best to check condition of your wires insulation to make sure there is no breaks along the lines

rewire the amp from the dek all through to the speakers.
