As the title implies, I have very bad engine whine coming out of my speakers.. i just installed a jbl cs60.4. it sounds great when its loud, but as soon as the volume goes down the whine is awful. when i rev the engine the pitch goes up. Anyway i can stop this?

Also, when i turn off my car, even when the volume is all the way down i get a huge thump out of the speakers. Are these problems related?

i am an idiot

My Crystal Ball tells me you have a Pioneer radio. It also tells me that the following webpage will help you get rid of the noise.

The above WILL also fix Alternator "Wire" noise on certain JVC radios as well.

Engine whine in an amplifier is commonly caused by a ground loop. Read the grounding sticky post and be sure to measure your ground return resistance, you want it to be less than one ohm. Also, check that none of your RCA cables or speaker wires are damaged, and make sure your gain is not too high.

If it still whines, ask it if it wants some cheese. After that threaten it with the metal recyclers and see if it starts to behave again. After all that, verify that you do not have a pinched rca cable somewhere or that if you have a crossover, the noise is not being induced there.

Top Secret, I can tell you but then my wife will kill me.

you need to run your power the oposite side of your rca's going back to the amp and if you already do that you can get a box form walmart r a local car audio place that you put your rca's into that ends the whinning

Rob, you should know that only works with Sony amps. Sony amps LOVE the cheese.
