i have a full car sound system in my car. now i get this whining, sort of staticky noise when i turn the car on. also when i hit the gas the sound gets louder. makes my car sound like a R/C car lol. its really annoying when i turn down my music to volume 1 or 2...and i hear this annoying sound. it sounds like its coming from the speakers. what do i need to get to fix this?.....i heard that i need filters
