Equipment Repair and Modification
Getting ready to do a new build with 2 zapco 9.0's and 2 6.0's .
But one of my 9.0's has a problem and it won't shut off. I only realized because the amp powers my zapco eq and when I shut the car off, the eq stayed on.
So the amp won't shut off, other than that it bangs!!!
What I need to...
