[QUOTE="MisterAutomatic, post: 7388935, member: 634469"] Hello everyone. Outside of introducing myself, this is my first post. I have no prior experience installing car audio, but this is something that I definitely want to know for myself. I build computers for a living under my own business, but I don't know much about electrical. As for my situation... I have a 2004 Chevy Malibu Classic, and I'm installing a Pioneer AVH-P4000DVD. Due to the issue of not finding a wire harness adapter that works on my car I had to find the diagram to the stock harness and wire everything directly. I installed a Kewood radio about a month ago, so I figured that this wouldn't be any more difficult. I lied. I was able to get my unit powered on, but I wasn't getting any sound. I let the tech at my job check the wires, but what we came to find was that my issue has something to do with a ground wire not being connected, because we were testing the audio from a usb drive, and this is a known issue for that unit.
