Noise after installing Amps and EQ. Any audio experts advice appreciated!!

[yac2727]

I installed my system in my M3 this weekend it sounds great. It consists of:

1/0 guage stinger wire
IXOS gamma RCA
Alpine 3342 Digital Signal Proc. EQ
Stock Head Unit with a Navone N-7V Hi-Low
Dynaudio seperates front
ADS coaxials in rear
2 12" Lanzar DC 12" (the oldschool Lanzars) for bass
1 MMATS LM2100 for midbass in front
1 MMATS SQ4070 2 channels for tweeters in front 2 ch. for ADS in back
1 MMATS SQ2150 for bass

The system sounds INCREDIBLE, just as you would imagine. Problem is extremeley annoying clicking noise coming from my tweeters at lower volumes. Sounds like ignition spikes. It's not the wires (already tried that), it's not the amps (I muted the amps and it wasen't them). It seems to be a mix in the front between the stock radio, the EQ and the HI-LOW component. Anybody else run into this problem after installing their system? What did you do to resolve it??

If you are using a periphial then that is probally your problem. Your never gonna get perfect quality while using a periphial device to transfer signal. The signal is basically jumping from one piece to another through air to convert the signal into your RCA's. I bet if you add an aftermarket HU with your setup and don't use the stock it will sound great.

well youve started to narrow it down, keeping working the signal back to the headunit to pinpoint at what point the noise is entering, once u narrow it down we can work from there.

I moved the Hi - Low converter (Navone N-7V) next to my amp, and then I isolated the EQ power supply. The noise was gone. I don't want to spend the money on an isolated power supply for the EQ (400 dollars), so I think I'm going to try power line filters (you know the big coils), and then I'll just try to move the HI - LOW converter under my passenger seat. Do you think this could solve it???
