yeah you will loose the ability to change the speekers to left or right side go to a local audio shop they will better explain it you i wanted the same thing thats what they told me but I just went and bought a whole new head unit but it is possible.
There was a discussion about this earlier this week. All your gonna need are line out converters on your left and right rear speaker channels to run two amps and BAM!! you got it.:rock:
I think I'm gonna build a wall in the back and run 2 18's! :rock:
Only after I upgrade everything else first. I have 2 12's in there now with everything else stock, and I have to turn the bass waaayyy down. :biggrin: :laugh:
