    Removing the factory amp and replacing it with an aftermarket amplifier is not that difficult. All you have to do is provide enough power, a good grounding point and an amp turn on wire. In order to provide your aftermarket amplifier with the factory audio signal, you may have to use a line out converter. Here is the Line-Out Converter you need:

    If you’ve never installed car audio before, we advise you to take your car to an experienced mobile audio installer. Hope this helps. Good luck.

  3. I am looking for a stereo wiring diagram for a 2008 Scion tc. The Scion stereo part# is PT546-00080 made by Pioneer. There is a subwoofer in the back under the rear deck and it has an ipod attachment and aux plug in the center console. I would like to keep the head unit and ipod\ aux inputs, delete the rear sub and add an Alpine 1000watt amp and 2 “R” series 12″ subs. Also, The amp that I have hooks up via RCA jacks so any help there would be appreciated.
