Alright I have a few..unique circumstances. First off this was my first head unit installation, and the car is a 1979 Trans am, not the most..user friendly for electrical installations. But I had a casette that came with the car, but took it out for a Head unit from circuit city. It is a JVC KD-S590, and I had it all wired up and it worked fine. A little static in the sound, but I hadn't finalized the wireing. So I was driving along and it just stops working. I get home and check the wireing and it's all fine. I finalized the power connections and it turns on fine, and even plays. But I hooked up the speakers and they dont emit any sound. No matter what the volume, I don't even get static. I emailed JVC, but they should "get back to me within 5 days" and the nearest JVC retailer is about 45 minutes away. Everything looks to be working fine, and no fuse is blown. Anyone have any ideas as to what I can do to fix this or what. Thanks in advance.
