Okay, let me break it down.

I recently did what i call operation quiet my carter fuel pump, so, now the fuel pump is dead silent (almost) and i found a new noise because i cant hear the fuel pump anymore.

Weird, actually; whine noise comes from the left tweeter only when the car is running and the stereo is off, WTF?

When the car is running and the stereo is on, there is no noise in any speaker.

Even with the stereo on and the cd player on pause or mute there is no noise, only when the stereo is turned off and the noise does not appear change or respond to engine RPM.

FWIW i have a central grounding bolt for all of the audio gear.

All of the audio cables (speaker and RCA's) are not next to any power wires.

The stereo is in my 84 GSL

The stereo consists of:

Clarion DXZ845MC head unit
Clarion APA2200 2 channel amplifier (for the mids and highs)
Rockford Fosgate 250a2 amplifier (for the sub)
Rockford Fosgate 8" sub in the rear
MB Quart 3 way component system
4 Gauge wire to a fused distribution block,
Then separate 8 gauge runs to the amps and head unit
Again, all grounds including the head unit are at a central grounding bolt
All new 12 gauge wire to all speakers
All connections are soldered

Oh and a MSD 6A ignition box (dont know if it matters)

This is driving me nuts, not because i sit and listen for noises when my car is idiling, but because it seems something isnt right.

Also, on a side note, i dont cut corners and installed everything myself properly, but i am no expert, what the heck is going on?

Please help, any input would be great!
