No RCAs. The OEM head unit is a POS. Mine was only 8 years old and failed. It also controls air conditioning and heating so something to look forward to.

I have a v6 also. Basically, what you need to do is tap into the rear deck speakers, then either use a LOC (line output converter) to turn the speaker signals into RCA input for an amp, or use an amp with hi-level inputs. Then you run signal from these speakers into your amp, and on to a sub in the trunk. You could go with a all-in-one unit from Pioneer or Rockford Fosgate (sub and amp in one box) or run a separate amp and sub box. I have a 600 watt Boston amp and a Boston G3 12" sub in my trunk. If you use a 10" sub you can gain more trunk space. 600 watts can rattle your teeth loose. More info and ideas in my signature link below.
