too many grounds

Yea, I said that because I have seen it happen many times and it is worth checking out, especially if the car has been chipped.  But if this car is as heavily modified as you say it is, the source could be anything.Support the12volt.com

David, thanks again for the hospitality. My wife and I enjoyed hanging out with you... The ECU right now is stock until we boost the car... when??? unknown... I had a bad feeling that the ECU would be the problem to my noise... so, even if I re-run my RCAs I will still hear noise? I can remove the screws to the ECU if there are any. Funny thing is that sometimes the noise is there and sometimes it is gone... The G rides rough, and as you saw, the motor mounts totally vibrate the car. I don't know if that extra vibration is messing up the HU in some way.

Yes, the G has performance mods, but no CHIP, no performance mods that involve electricity except for grounds from motor to chassis. We are back in Albuquerque, so, this weekend I will work on the system... wish me luck. Mark "Hamzter" Cinense

Enjoyed thoroughly having you here! Next time you're in Cali, look me up again! Loved the chat! Well, short of what we already did... I got nothin'. POSSIBLY re-running the RCA's, but if the ECU is what's causing the problem in the chassis, then no re-running in the world will help! Good luck!It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
