My car has a JVC am-fm-cd player and the harness looks factory installed but it may be generic.
The volume has been in and out. I'm driving a long and put on brakes no sound, accelerate again and got sound, it continues to go in and out as I drive. Then on a job, my helper had to drive my car while I drove the truck.
When we arrived he had my stereo blasting away with his music. I said how did you get the volume to work? He said, he turned the sound up. It has a digital volume indicator and higher than 25 is pretty loud. After the job it lasted a day or so and went back to the in and out, especially when braking or accelerating. So, my helper got lucky or maybe a loose wire. I removed the stereo today and saw the harness and no loose wires, except a black wire from the stereo. I grounded it and all I got was a non music sound from the rear speakers. I popped the front off the stereo, push all buttons, turned the volume all the way up etc. Nothing no volume. Could this be an internal problem to the stereo itself? I really thought it was a loose wire with the way it would react when applying brakes or accelerating causing the wires to touch and not touch. But it seems not. Any help here?
