first off wanted to say thanks for the great advice on here. I am buying a alpine amp have new speakers installed my question is how do i know what wires to tie into. is this har to do. I get i need to remove tank to run power and ground but i assume there are many other wires that need to be hooked up. Is there also a way i need to hook it up to power on only with the key? i assume i do this by tapping into another power source but how do i know what wire this is and where to tie into?
