My girl has a JBL audio sub/amp combo - power, ground and input wire - which she wants installed in her Jeep Liberty. Power and ground are easy, but I am wondering about jumping the rear speakers for the input. Any help would be great.

get them behind the headunit, or if there is a amp in the rear.

 

I think the amp is under one of the seats. Can I just jump the wires coming off the amp?
