Would faster get engine whine than static from a bad amp ground.
I did an install of a new hu last weekend, thing putting out a LOT of pink noise, and it'sa constant noise that doesn't change with changes in volume up or down, but when volume is muted it lessens by about50%. No engine whine changing with rpms, just noise. I tried every trick I know, grounded by negative lead, noise. Negative lead and chassis, noise. Grounded the rcas, same noise, used a separate battery not connected to the vehicle's electrical system, same noise. Used filters on the rcas, same noise. These are just some of the things I tried, all yielding the same result. I suspect at this point that the hu itself is the problem.
