Hello, New TLX (base) owner here. I have a sub, box, amp, wiring kit, and Line Convertor from my old car and I'm considering adding all this to my TLX at some point. So in my old car. I soldered the Line Converter wires to the existing sub wires. However, I'm wondering if I got a wiring harness so I could just simply unplug the harness leading to the stock sub and plug it into another identical harness that I hook up to the line convertor... thoughts? Are these harnesses available for sale somewhere?

 

I tried to de-pin the harness so that i can just re-pin it when returning it but it was too much of a pain. ended up just using wire taps.

 

cut the harness off the factory sub (bit that clips to the car's harness) and solder it onto your LOC with shrink wrap and insulating tape to avoid interference.

If you want to keep the factory amp you should use wire taps.
