80 cj stereo no sound from new speakers and wires please help
Cj jeep 80
Jeeper
Well I decided I wanted a radio in the old jeep. Most of the wiring was messed up and abunch of it wasn't there. I had to run a new power wire to the fuse box and a memory wire to the battery the old ground wire was still there so I used it. I had to run all new speaker wire I bought a marine radio and speakers so maybe they'd still work after it rained with the top off. But my problem was I did all that then hooked up the radio and plugged it in and the radio came on seemed to be working good all funtions worked. But I had no sound coming from the speakers. I messed with the ground wire I unhooked it and ran it straight to the - battery terminal and still no sound. I took the grounding wire off and sound came on for a couple of seconds and the the sound went away. Why was it working without the ground wire? But it had sound but just for a few seconds. I'm out of ideas and that fancy radio does me no good with no sound. Please help!!!
