Question about Performance Teknique ICBM-772 Car Audio Amplifier
All of a sudden my subs started working and i did not get to check it out until the next morning, i replaced both fuses in the engine but the amp still did not work, as i was looking at it it turned on for 15 seconds then shut off i started checking all connections when inoticed the ground terminal was partially melted and the end of the ground wire was now black, the amp diagnostic light is on and goes of when i disconnect the negative input.
Sounds like a typical case of poor conections causing the amp to fail... take the cover off of the amp. Inspect where the terminal blocks meet the circuit board. SOmetimes you can repair it sometimes its just too far fried..
