I took out the stock factory JBL amp that was under the passenger’s seat and replaced it with the Alpine amp. There are three plugs that you have to disconnect from the JBL amp. I tapped into one of the plugs that came off the JBL amp which ran to the door speakers. I ran my wires from Alpine amp to the plug which ran to the door speakers. Once at the door speakers you can use the wire harness to plug into your new speakers.
