So i'm picking up an '08 Liberty tomorrow and was wondering is it possible to connect an aftermarket amp and sub to the stock head unit? Its currently in my ZJ, but I want set it up in the KK. Any info. and other advice is appreciated.

I remember doing this with my sony amp back in the day, my amp came with a small wiring harness that plugs into the back of the amp and the other end was a pigtail of 4 wires. 2 wires + and - for the right rear speaker and the other 2 for the left rear speaker and it just got its signal from there. For the amp remote turn on I hooked it to the cigarette lighter that comes on with the ignition.
