Installed:
Pioneer 3000IB H.U., 2 RCA preouts
Pioneer 6 1/2" (Front)
Kenwood 6982ie 6X9 (Rear)
Infinity Power Reference Amp, 140WX4
4g. power wire & remote turn on wire are run on the right side of my Taurus. The RCA cables (2) are ran on the left side of my car. Ground is connected to a bolt in my trunk.
Front speakers work just fine, but the rears produce a loud whining sound when the engine is accelerated. I also notice that you can hear my power window(s) motor when I roll up/down the windows through the speakers. Plus, nothing comes out of the rear speakers when faded to the rear (except engine noise). You can hear every little thing through the rear speakers, like when the CD player turns on & what not. RCA(s) are connected correctly (front on H.U. to front on amp, rear to rear) with little to no interference. I never had this problem (except for the fade part) until I installed the Pioneer H.U. What's up?
