I also connected the Regency M100 scanner output to the dash speakers and the CC1's "Radio" input.

I had previously taken the dash speakers (4 Ohm) and added a resistor across the terminals to drop their impedance to 4 Ohms, which is what the Micor system wants. But since I will not be using the Micor, and instead using scanner output to simulate radio traffic, I needed an 8 ohm impedance because this is what the Regency output needs for a load. By connecting the dash speakers in series, it gives 8 Ohms. Perfect.

It was awesome to hear the scanner output both from the dash speakers, and on the outside speaker.

Next week 0327 goes in for tune-up, smog check, and some minor mechanicals.

I should proofread a little better before I hit the Submit Reply button...I meant I had added the resistor across the 4 Ohm dash speakers to drop their impedance to ~3.2 Ohms. By removing the resistors they reverted to 4 Ohms.
