I tried to wire 2 amps. One is a 2 channel amp for my subs, and the other is a 4 channel that i have for mids and his. When I start my car there is a loud whining noise coming from the speakers at any volume.If i disconnect the 4 channel amp. the loud whining noise is gone. Can somebody help, im pretty sure on how to wire multiple amps, but if somebody could help me out, i'd appreciate it.

Its probably the altenator whine. Does the whine increase with acceleration. If so try regrounding it. Also what equiptment are you using and where is it grounded at.

There is no problem with Pioneer radios. The problem is that NOBODY follows the first line of the installation instructions. 1. Remove the negative battery cable from the battery.

I thought you had a 4 channel amp on your highs. It is not uncommon for the Output chip to be taken out due to improper installation. Are the speakers connected to the 4 channel amp or to the deck?
