i think you have a high restance ground on one of your speaker leads. diconnect one at a time until you isolate the lead the make sure it's not grounded. this usually happens a the leads on the speaker touching the basket or the car.

the problem was decided to be the alternator rectefier. the only problem was i couldn't convince the coustomer of this. so i sent the coustomer to the mechanic that checked the alternator for more info.

Glad to know it worked out. How did you isolate the alternator as being the cause?

I also have an alternator whine in my '02 Avalanche. The noise is still there when I diconnect the RCA from amp. I am useing large power and ground leads. They are running on the opposite side of my truck from the Stinger RCAs. My ground connection is only about 8 inches from the amp. But my distrubution block is only about 6 inches away. How far should these 2 be from each other? I never thought about this as a possible problem.

I have been reading this site for a while, and you guys are great!

If there are any other Avalanche owners with a built system out there, let me know i need help with a noise problem - Page 2 -- posted image.

Less

it dont matter how close your power and ground cables are to each other. but it may matter how close thay are to your siginal cables. make sure the cables are at least 12-18 inches away from your power or ground wires. also check the resistance to the neg. side of batt. terminal from your ground point at the amp. the body ground at the battery is also important and is sometimes to small so try to upgrade it. there is a lot of questions about your system that needs to be asked and answered befour you can solve you noise problem but post questions and im sure someone will try and help.
