i have a kenwood 9102d amp and it isnt workin. i have put different amps in my car and they all work fine, so im thinkin its not my wires. what happens is when i have it all hooked up, it wont turn on. but when i mess with my ground cable, the amp will flicker on and off. for example, when i touch the ground wire to a good ground, the amp will flick on then off real quick. any ideas will be apperciated.
