I also have the CDR220.
It's been a few years since I installed my PNP kit, but I think it has 4 speakers.
The kit came with the front-to-rear wiring, which was the most time-consuming part of the install. (Initially they sent me the wrong cable, but followed up quickly with the correct one once I let them know.)
This is one mod that's a must-do, for sure.
