So what kind of system do you guys have in your monte? I just put one in over the weekend. I got a pioneer appraido that has a 7" screen and I can throw over all my apps from my phone to the deck so with that said I have navigation and will be getting the OBD II app soon, put in a 12" jbl kicker and did a music wave lamp in the back window that lights up. I did that last part for shows I will be attending.

 

sony head unit. stock door speaker. sony 6x9's in rear deck. 800 watt amp dual kicker C10's in a ported box.
