Question about Car Audio & Video
My jbl gto4060 amp int the back of my car seems to have just stoped working there is power going in to the fuses but thats just about it no sound from the sub what so ever
( I am assuming your amp does not turn on)
You will need a test light. You can get one at a hardware store for a dollar or two. clip the end of the test light lead to a good ground, and touch the needle to the red 12v constant that feeds the amp. If it lights up then you are getting power from the battery. Next, turn the car and the stereo on and touch the needle end of the light to the small blue signal wire that goes into the amp. This should light up as well. If either of these don't light up then the wiring is faulty. If they both light up then we need to test a bit more.
First make sure your ground wire is tight at both the amp and the car body. It should have metal to metal contact with the car (no paint on the contact area)
