[QUOTE="Dbld54, post: 8855157, member: 689130"] Almost at a perfect finish line. I bought a new HU and amp which solved almost all problems. When the car is running, and the radio/bluetooth playing, there is a slight whine. It can be reproduced when using the power windows and when accelerating which is where it's most present. Could it be because i don't have a negative 4awg wire from the battery to frame? I added a HU ground to frame..no help. I also included pics of my current ground point in the trunk for the two amps, one 4awg and one 8awg piggybacking an existing ground location. I understand a ground loop isolator might help but keeping as last resort, I'd prefer to solve the issue since it wasn't present before. RCA filter i dont like due to SQ degradation. What do you think? [/QUOTE]
