[QUOTE="toy4x, post: 2955249, member: 571120"] To everyone that has anymore ideas, Here's what I have: Stock Bose HU has 2 low level outputs that I soldered rca's onto Rca's go into an Audiocontrol EQS...front/front rear/sub From eqs goes into fosgate 4 chan set for 2 inputs and fosgate 2 channel 4 channel is running set of rnbw germs and 2 chan is running 2 infinity10dvq running 4g from battery into 1f capacitor grounds for amps and cap are running into capacitor back to battery. My noise is alternator whine and just noise. With only music on, no noise....with car on a lot of noise...if I trun my stereo up to a bout a medium volume i cant hear it any more. Also if i unplug the rca's at the eq and touch the outside of the rca to the outside of the input of the eq's rca..noise gets much louder. Here's what I have done... Bypassed the eqs and ran the rca's straight to the amp, noise gets louder. unplugged ALL the rca's...still noise but gets less. unplug the eqs so it gets no power...still noise ran the ground from the EQS to the battery, still the same amount of noise if its grounded at the battery or at the grounding point 2" from eq. grounded rca's before the eqs..no change run different rcas from the eq to amps...no change turned off one amp and switched inputs to other to isolate if amp problem...no change in noise Only thing I can figure left is to ground my headunit. But since it's a stock headunit with what looks like speaker wires coming out of it, How do I ground the HU?? There is no actual RCA's in the back and since I have disconnected the rca's from the headunit and there is still noise...how can this be a headunit problem? Amps are being grounded at the battery so I can't believe it to be an amp problem.... Please give some ideas??? [/QUOTE]
