Radio install help 66cuda

cosgig said

You may have all the wiring you need under there from the old radio. There is a red hot lead from the harness that is hot when the key is on. Your ground can go to a screw fastened to the bottom of the dash. The speakers are blue and green on most aftermarket radios. For the constant hot for the memory you can crimp a spade end on your memory wire and unscrew the fuse box and look on the backside of it. There are a couple spade terminals on the back, one of which should be hot all the time. Just slip your spade end over the terminal and refasten the fuse box. Or you can slide it over one of the fuse blades on the front, you might bump it on occasion though and knock it off!!

Good luck with the project, Geof

This, "except."...................

1--Make SURE you have it fused, use an inline fuse if none is supplied

2--You didn't elaborate on the system---is this a one --piece radio, or does this have a separate (trunk) amp? How much audio output is it rated for? If it's much over 10W per channel (just picking a figure out of the air) you need heavier wire than you can tap into in the fuse box. In that case, you'll want to "get into" heavier points under the hood, like, say, the starter relay battery stud, and a "great big" fuse

3--You need to decide if you want to run the main radio power "constant" so you can have it on with the key off or out--or whether you only want the radio on switched accessory. There are two busses in the fuse panel. One is "constant" hot, the other is switched through the ACC of the ignition switch
