Incessant Whining!
Nope not that kind...
I've developed an electrical whine that is audible in my sound system over the past year. I'm interested in eliminating this whine and getting back to my "sub-par concert quality" system. System Specs Sony CDX-850MP Stock MACH 460 Amps and Speakers Best Buy Adapter Harness Rockford Fosgate Punch 125a Amp JL Audio 10" 10w1 Subs Power Wire on Drivers Side of Car RCA Audio and Amp Signal Wire on Passenger Side Amp Grounded to floorpan XM Commander connected via RCA Cable to Aux Input Symptoms
It was suggested that I run everything to a "common" ground, but how can I ground a radio system to a amp system that can only be grounded in the rear? Explain what a filter is and how it could help my situation? (ie is it electrical or audio?)

Re: Incessant Whining!
There are two little capacitors on the sides of the coilpack, more than likely they are bad, they are there to prevent ignition feedback to the audio system. They are inexpensive and available at any dealership. I had this problem with the one that is on my coil, replaced it and most of it is gone but my MSD over powers it. Another area to check is the jacketing around the plug wires, they could be breaking down and letting some RF energy into the sound system.

Re: Incessant Whining!
that is why I said coil packs, mod motors have two caps, one on each coil. Looking at the coil from the front of the motor, the passenger side one will be on the right side of the bracket and the driverside coil should have it in the same place.
