OK i know i should be using low inputs and all into my cheap crapy amp but im not im running th high inputs for now. my question is does anyone have a wireing diagram for a noise eliminator to go on the high inputs so i dont have to listen to the engine "whine" all the time over the speakers ( not bad with pcb's and a soldering iron. and too cheap to buy one.). the other thing is that the remote wire on the head deck is always on. even when the head deck is off. but if the ignition is off the amp then turns off. installed hunreds of head decks and amps but never had this problem. help anyone pls.

Will get an RCA cable when can be bothered. but for now no-one has a filter schematic they can post?????? PLS.. some one has to have one
