help with wine?
help with wine? I'm getting some wine through my rear speakers. It's been bugging me for awhile now, but havent messed with it at all. I've got 2 ground loop isolators, two 1ph caps, and the whine gets worse with the AC on. The only thing I can think of is that the power wire is comming off of the ACC batt terminal. I'm the only one I've ever seen to do this on an F body. Does anyone know if that could cause it? BTW, I was a "shadetree car stereo installer for hire" back in the high school days, I never had this problem before. And yes, The power wire and RCA's are running down opposite sides of the car. Also, I've put 8 guage grounds on the amps, caps, and batt. I'd appreciat any help with this. If you want to see my setup exactly, I have a page dedicated to it on my cardomain page. Link is my homepage in my username. Thanks.
First of all it's whine. 
But anywho...
Do you know if it's from the amps or the headunit? You need to isolate the source first.
1. unplug the RCA's. Listen for noise through your speakers. If no noise, it's your RCA's either physical or interference.
2. If the noise is still there, perhaps a bad ground that you didn't mount well on a clean spot of metal. Shock Towers, Seat bolts, and seatbelt bolts make good locations for a ground, once sanded down a bit to bare metal.
But first things first is to try and isolate the noise to a particular component.

it also generally good practice to isolate and only have one ground source. this generally helps reduce whine. do not run the ground to the battery, and pay the extra couple of bux for good "no sound" RCAs they are worth their weight in gold.
ohh yeah another little trick that can also help to reduce ground noise is to cut the ground wire for the radio, and run it back to the same place that you gorund the amp to. this is also a little trick that can help you out with ground noise if all else fails.
