Trying to install a stereo

Greeting A bodies,

I am trying to install a newer stereo system in my 65 dart, so here is my game plan.

1st Switch the Voltage regulator from the 6V stock to a 12V.
" so i don't fry anything (or vise versa)

Then I umm, yeah.

I have seen the older radio sets were the wires connect in the back. But this newer ones have all these plug and play sockets and whatnot in the back. When I look in my open consel were a radio should be I have my antenna cable and a wad of multi colored wires.

Has anyone installed a newer radio to there old mopar before?
A walkthrough or step by step instructions would be great.

Im just sticking to the speakers in the back and the ones under the dash.
I don't need a subs or amps, or TV screens and all that jazz.

Need to go down the street rockin out knowing "thats right im bad" :glasses7:
