Aux whining feedback
 

Hey guys,

I'm having whining feedback when i accelerate in my 2007 is250, and I'm out of warranty so the dealership wont perform the TSIB for it. Any suggestions on how to fix it, and get read of the whining sound? i looked and saw there might be a diy for the aux port filter, and also a different aux cord i can use called the Kensington K39203US Audio Cable, any other suggestions?

Thanks guys!!
