Sorry if this was posted already, but I was wondering if the stock unit has an RCA sub out to hook up an aftermarket system. I know it has the stock sub, so I'm assuming there is some sort of sub out from the factory unit. I havn't had time yet to take out the unit and look at it, but I have a JL 10W3v2 and an Alpine amp that I'd like to add to the already stellar sound, but don't really want to have to get an aftermarket head unit.

 

There's no output on the stock head unit. You'd be better off to get an aftermarket head unit since it will have actual sub outputs where you can adjust the level of the sub from the head unit.
