i dont know much about audio stuff and i have static coming from speakers and a little whistle noise that sounds like a supercharger. the whistle increases pitch as the rpms go up. any ideas? thanks

 

its grounded out somewhere, had the same thing in my old car and it drove me nuts

 

yeah the guy who had my car before me installed it. I took a look at the wiring the other day and everything looks like a mess

 

ill check that out tomorrow thanks

Start with the right hand column selection number two, read, and move to three. Continue until you understand enough to buy a soldering iron, go back to your car, and rewire that rat's nest!

Be patient. It takes a while to do things right.

 

I can only guess from reading your message. It could be something as simple as an inadequate wire attachment to the speaker. But (and much worse), it sounds more as though you are picking-up noise from your alternator (since the interference increases when increasing engine speed).

As dave079 mentions, it’s probably a faulty ground or poorly shielded power cables.

To fix this, you will need to expose the H/U and its wiring.

1. Take the center console apart and pull the H/U forward so you see the wiring.
   
   
2. If you have a lot of grounds going to various places (either to metal or other ground-wires), try relocating all the grounds (as much as practical) to a single place where you know you have a reliable ground. What you are doing with this exercise is eliminating a ground loop which can cause the problem you are experiencing.
   
   
3. After relocating the grounding wires, and before putting the dash back together (your H/U will be sitting outside the dash but wired for power), start the car and rev the engine with your radio on. If it’s good (no noise or whining), you’re done and you can put everything back in place. This usually fixes the problem, and you probably won’t need to go to the next step (described below).
   
   
4. If you still have noise, you must begin checking your power wires (which is a real pain). In this case you are looking for powered wires that have inadequate shielding and are in proximity to other power wires or ground wires. The bare area probably doesn’t physically touch (in this case you would blow a fuse if your fusing is correct); but if it’s in proximity and exposed, you have sound pollution. Probably the best and most simple approach here is to establish new attachments for your power wires.

Please let us know how you resolve this issue. We will all learn from your experience. I share your pain since I know how frustrating this type of problem can be. Thanks for posting.
