[QUOTE="Dbld54, post: 8845682, member: 689130"] Hi, I needed Assistance troubleshooting an annoying whine coming out of my speakers. I think it started when my ground point in the trunk, became loose and I had to try different areas but not too sure. I have two amps, I've disconnected the subwoofer amp to try and keep it simple. This leaves the 4 channel amp. Clues: The sound does not get louder when I increase the volume. It is present even with volume at level 0 on the HU. If i disconnect the 4 rcas the whine is gone. If I connect any rca cable to any of the Jacks the whine returns. Even if it's just 1 rca, that one speaker will whine. I've tried several ground points, the latest is using an existing ground from the stock Ford wiring. The ground points are sanded and tightly connected. Amp fuses are fine. Please let me know if you have any ideas. Thanks [/QUOTE]
