I am trying to keep the factory head unit in a 2004 Alero. I am assuming there is no remote lead. From what I have read so far I want to use the ignition wire for my remote turn on.(correct?) Now the main question is Do I splice my ignition wire, if so then what is the best way to run the lead to three amps in the trunk? ie: multiple wires from front of car or 1 wire into the trunk and splice from there?...I am quite unsure....thanks for the help.
