I assume which is for the amp and everything. Power and audio for sub. Has anyone done this install on there TJ. I am sure I can't be the only one to do this. Is there a wire harness kit or something like that to make everything work.
It can be done. The factory plug has wiring for the power, ground, remote turn on and + and - for all four channels. The factory sub takes a signal from all four channels so that no matter how you adjust the fader or balance it will still get a signal. It then bridges these four channels down to two channels driven at 80 watts at 2ohms.
When I added a console to mine, I just grafted the wiring into the line level speaker wiring from the back of the radio and then hooked up the power, ground and remote. The sub controls from your radio will be useless unless you add an amp and don't use the oem amp.
