Okay need some help. I bought my Grand Prix GXP and it already had been wired for a system with the Factory Touchscreen Navigation Monsoon System. Really do not want to get rid of the Factory Deck.

Someone said there is RCA outputs on these decks?? Is that true or no? Or did they just splice the speaker wire for the RCA output?

What would you recomend doing for running a 4ch Amp and aftermarket components? I have 2 sets of MB Quart 6.5s. Going to make plates for the rear for 6.5s and ditch the 6x9s. Let me know your thoughts please.

I am going to be running oldschool PPI PC4400 on my compoents and a PC2400 on eaither a single 12" or 2 12" subs.
