My friends amp turns on for like 3 seconds when the car turns on, but it's in protection mode. We messed around with the ground today, and when i took it off, the light went off, but when i put it on, the protection light came on. Anyone know what this might be?
The thing is, it worked a few days ago. All of a sudden it just stopped working, i will try that though. Also, the amp is a piece, it's an SPL amp. thanks
