hey little guy, listen to these people, they have been through the EXACT same shit as you are going through right now...You asked a question, now here is what has been offered as advise to help your problem...
First check all the gounds
change the fuses
remove the speaker wires and make sure amp still comes on
Use a digital multi meter (DMM) and check what, i have no idea...So ask these guys
What do I need to check for with my DMM to see if amp is dead, and could any of you give me a small tutorial on how to check this out???
