Stereo noise, whistling in stereo Options

[tigernate29]

What can I do about that terrible whistling noise that comes through my stereo when the engine revs up. I have two mtx 5000's with a 600 watt profile amp. I put a 1 farad rockford fosgate capacitor on it hoping it would help. It did a little, but the noise is still there. Anyone, please help.

Before you go crazy checking all of you wires.

Start the car and turn on the lights. Make sure you hear the noise. Then unplug the rca's from your amp. If the noise stops it's either coming from the rca's or the radio itself. If you hear it with the rca's out regrounding the amp should fix it.

If the noise stopped. Plug the rca's back into the amp and disconnect them behind the radio. Still hear it. Re-run the rca's, think about a good quality shielded set of rca's.

If you had no noise with the deck unpluged. Try grounding your deck somewhere other than the stock ground. I've seen some crappy grounds from the factory. Just get a piece of wire hook it up as a temp and try a few different grounds.

Let me know if you still have noise with a new ground. I have a few more tricks.

I've never seen rca's and remotes run together that caused a problem. Ususally it's rca's too close to wiring harnesses or computers that cause a problem. If you do need to cross a power cable or wiring harness try to do it at a 90 degree angle, you will be less likely to induce noise.

Ground loop isolators do work but at a price. Use lose some clarity and signal strength. I try to save them for a last resort.
