Hey guys my old man got a amp installed by a Stereo Place today, and it keeps blowing fuses, it worked for a few hours and keeps blowing 25 amp fuses all the time now and when it is running (not working but powering) the lights in the car dim and go back to normal, dim and go back to normal, any idea's what it could be?
Faulty Amp or they wired it up wrong?
