I recently hooked up a new amp to power my front speakers. (also my
rears but I haven't tried them yet). There is a horrible engine whine
that gets higher pitched as I accelerate. Also there is absolutly no
vocals whatsoever. There is only background sounds and background
vocals. I have tried multiple grounds and a ground loop isolater.
all of my grounds have been to bare metal with the paint off. Please
help!

Try replacing your rcas. Sounds like the rca ground may be bad. Could be
the HU as well, but try another set of rca's first.

Good advice from Paul regarding RCA cable grounds. If that is the
problem, the following may work. Go to the connection where the RCAs
of the head unit output connect with the cables to your amp(s).
Using a radiator clamp, bind all four RCA plugs tightly so that metal
of all four plugs are touching. Before you tighten the clamp, also
place a medium gauge wire, say #8, in the bundle so that it is in good
contact with one or more of the metal parts of the plugs. Connect the
wire to a body ground of the car (any nearby screw into the car's body
will work fine). If this works, it will not only completely eliminate
the whine, but will also dramatically enchance the system's fidelity
and separation. I discovered this one day when tinkering with my
Soundstream TC308 about 15 years ago. One of my lucky days! Good
luck, Stan Collins
