When i play my sub at a higher power...a high pitched squealing noise comes from inside my trunk..anyone have any idea what it might be?

it doesn't do this at a lower power level..

so the power is making something squeal i just dont know what

 

It sounds like however put it in didn't know what they were doing. I'm going to guess the power wire and rca's are right next to each other causing inductive interference.

 

i'll play around with them on saturday...hopefully that works..thanks
