I want to hook up an aftermarket amp and sub to 2004 tl.
I know that it is possible to tap into the wires that are going into to the stock subwoofer,a and convert those into a low level output (RCA) using a line output converter. So where I'm running into trouble is where to find these wires and how to connect them. May I also mention I have one 12" alpine type r subwoofer, and a alpine mrp-500 amp that I want to use to power it. Any help is much appreciated car audio is not my thing
