your jk didn't come with a factory sub and amp, are the speaker wires still in the harness going to the back of the hatch area? or are they totally omitted,,,,, planning on leaving everything else stock and replacing the speakers and adding a sub in the back and was hoping the factory would include the wires in the harness and just not install the sub depending on the build sheet.

 

If you got the non-infinity option with your Jeep, you will not have the wire harness to the rear.

 

If your jeep didnt come with the factory sub and you dont have the infinity system then I am pretty sure your only option is to purchase a new headunit with pre amp outputs as well as an amp. Then just wire it up yourself. Thats what I had to do.

 

ok,,,, thanks for the help
