how can i stop whistle noise goin through my amp?
Need more info mate... what do you mean whistle noise, does it change with the revs of the engine? What amp/amps? Head unit? etc. Did you install yourself? Sounds like your trying to ask about a blown rca earth...
"I realize you were young and inexperienced at the time, but in hindsight you should have chosen your parents more wisely."
you should always make sure power lead to your amp is on opposite side of car to rca leads
and sometimes you will need a suppressor you can get inline ones that connect to ur rca leads
