The amp is brand new. There was no high pitched sound unless the engine was running.
When I turn the key to "run" position, I get the high pitched sound for 10sec and it stops. When I turn the engine on the there is a whine that is added to that high pitched sound. ANNOYING! 
I ended up grounding the head unit to the amp and its gone. 
I really appreciate your help guys. Forums really help for times like these.
