High Pitch Sound

BruinBroker · December 22, 2003

Hello Everybody,

I have a Kenwood Touchscreen TV/DVD Tuner on my 2004 ES 330. I also have 2 10" kicker subs in a box with a US Acoustic amp. I havent noticed it before but when the volume is down real low there is a high pitch sound coming from somewhere. I can't point my finger on where but it might be coming from, maybe my speakers. It kind of sounds like a jet engine sound and it only occurs when I press on the gas. At first I thought it was my engine but it does not make that noise when the system is completely off. Originally a static sound could be heard from my subs, but that problems was fixed. I think I was too focused on getting the muffled static sound from my subs that I didnt notice the new sound that I have. Does anyone know anything about the problem and know of a solution?

Thanks

if your RCA cables are not high quality and too close to your power wire to your amp this will cause this problem try to seperate them. Then check your ground connection. to insure tightness.
