[QUOTE="mystikarkitect, post: 3171748, member: 569957"] Hey all, just wondering if anyone can help me. I've pretty much run out of options and ideas. Some of you know I installed a Pioneer Avic Z-1 HU a few weeks back in an 07 Avalanche. At first, with no amp in the system, everything worked great. Soon after I installed a JBL BP1200.1 amp in the truck and grounded it to the brackets that hold up the back seats in the Avalanche. I assumed the brackets hit the vehicle body so I grounded it there. The amp turned on fine but one of the subs was faulty (TC-1000 8") so I took out the subs and the amp. During the removal, the ground wire and the power wire touched and sparked. I turned off the positive terminal and removed all wiring. Well this is when the ground loop started. Im not sure if it was the positive and negative touching or what but the next time I got in the truck there was engine whine. So the next day I ripped out all wires save for the RCAs and remote wire to see if that would fix the problem. It didnt. So I drove around for a while with this annoying engine whine in my relatively new truck. Something I was not enjoying. The HU still worked fine. So I came on here and saw possible fixes. There was no amp in the system anymore, so it wasnt the power wire interfering with the RCAs. So I got new RCAs. I bought some Stinger Bullett Series RCAs and took the old cheap RCAs out and put the new ones in. Still had the whine. I removed RCAs completely to see if that would remedy it, and it didnt. Then recently I tried the different fixes I saw on here. Tried grounding it at the battery, tried grounding it where the amp was ground. Neither worked.
