Got an email from Rod saying that if I had door speakers the harness the other guy sold me may not work.
So I am thinking of forging ahead without that harness and making this a fourth of July installation project. But, I have questions before I cut any wires...
1) Can I just unplug the amp from the back of my CDR210 and leave it in place for the time being?
2) If I wire up the "right front +" and "right front -" wires that were going into my old unit, will it power both the dash speakers and the door speakers too? Or, do I need to root around and trace wires from the door speakers and dash speakers to the existing head unit? (I sure hope I don't need to do that!)
Here's a copy of a PDF I found on the web for wiring aftermarket units I was planning to use:
