I just completed my installation of a pioneer head unit, targa passive eq, 88 watt jensen amp for front and jensen 300 watt amp rear. Both amps are grounded at the same point and powered at the same point. When I turn the head unit on while the motor is running I can hear a high pitched whine feeding thru the front speakers only. The whine increases upon acceleration. The hot wires run along the right side and penetrate the firewall thru the grommet just in front of the vehicles brain. After penetrating the firewall the cables proceed under the ac fan assy., along the the inner fender and lead right up to the positive battery terminal. The amps are grounded using one of the screws used to hold the right rear window frame assy. I also mounted a noise suppressor inline with inputs to the 88 watt amp. Any ideas would be much appreciated. Unless I crank up the volume the whine is enough to drive an extremely sane man insane.
Thanx in advanced.
