Okay so I just had Alpine Type-R speakers all around and 2 12" Alpine Type-R subs installed all amped up. When the volume isall the way down, my tweeters make a clicking noise, which they have never done that before. Also, when I accelerate my vehicle I hear a high pitched whiny noise, and it gets louder as the RPMs go up. Any ideas of what it could be and how I may be able to stop it?

 

sounds like a ground loop..... make sure your amps are grounded at the same spot..... make sure it's a good clean contact... no paint ....... if that doesnt help try grounding the shields of your rca cables..... check the deck as well...... also make sure the power wire is run down the opposite side of the car then your rca lines....
hope this helps

 

That sound is when the speaker wires are too close to an electrical part of the car. (such as the power wire going to your amp) so like mentioned, you have to run the power and speaker wires on opposite sides of the car

 

im gonna take a shot in the dark and guess u have a pioneer head unit?

 

Kenwood, im going tomorrow and i am gonna ask the guy about it and he should fix it because i dont really feel like pulling my car apart to do all of this, but thanks for the suggestions, ill mention them to him! Although im sure he knows it...
