I don't think the vehicle is pre-wired for DSP with sub, but the actual wiring schematics that we use at the dealership is the "online WDS" link at the top of the page if you want to dig around for the differences. Then you could see what all is different.

Otherwise, I'm sure someone on this forum has done that upgrade (as the DSP system sounds great!) and may chime in. If so there may be a thread on it already, have you searched the site?
