If you decide to run an amp from the beginning, the wiring changes some. You need to run RCA cables from the head unit (radio) to the amp along with the remote turn on wire. You will also need a properly sized power and ground wire direct from the battery to the amp. Then you run the speaker wires from the speakers to the amp instead of to the radio. This diagram is for a 2 amp install with a sub woofer. You can install one or just disregard the second amp.
