speaker noise?

[Predator Bird]

my speakers are making a weird noise, kinda like a feedback. its like a little whine that constantly plays, even w/ the music turned on and off. my stereo consists of, 6.5'' jbl in the doors w/ 40x2 amp, 6.5'' rockford fosgate components in the back seat w/ 50x2 amp, and stock components in the rear hatch. i also have 2 12'' mtx blue thunders w/ 400x2 amp to them. i have an electronic crossover too.

check the wires. I am only saying that b/c i had an alarm clock making noise and that was because the plug came out of the socket a little bit.

Did you ground the ground wire from your head unit to the factory ground wire? If so, undo it it and make your own ground from the body of the car. Much cleaner. The factory tends to use the same ground for many other things not even audio related so it gets a little noisy. Post back and tell me the results.

the problem were my rca wires. i had a cheap set in there and there was a bad connection. i ran all new rca's and even did a 3rd set b/c my new cd player has 3 sets of preouts. its sounds so much better now. thanks for your help.
