What do I need?

[Kenny Pollock]

I want to add a sub and amp to my factory system in my '06 R/T. What would I need?

[lumbergb2001]

an RCA adaptor...since you are going to leave your factory radio and then the rest....power wires and rcas....best buy or any shop should know what you need.

Yeah if you go to a shop that specializes in car stereos, all you gotta do is tell'em what you want in your car, and they'll walk you through with what they'll do and how much it'll run. STAY AWAY FROM BEST BUY. In my experience, the installers are mostly kids who learned how to install from the internet or ghetto rigging on their 87 tercels.
