I just picked up a 2013 Taurus sel. I ran all the wires for a amp and sub. Kicker L7 12" and a kicker 1500.1. I'm leaving the factory head unit since it's fully loaded. My question now is where do I install the line output converter (LOC)? I tried the rear speakers and it blew my head unit fuse twice. So any other place I can install this?
