Does anyone know if you can connect subs to the stock radio. Does it have preouts? Please provide info and pics! I want to put my JL's in but not sure if they will work.

Try search. There has been a lot of discussion on this. Too many list.

I put 2 12 inch w3 JL subs in the trunk.
the stereo shop I went to got tapped into the bose speakers in the back

Here is my kenwood installed sub with kenwood 700 watt amp.:D

Look at page three- wiring details on pre-amp line-level output from the head-unit. Easy as cake...
