Multiple Alpine CD Changers

[Vlad]

I want to add a couple more cd changers to my car, I spotted a KCA-400C on ebay, it says you can have up to 4 changers with it, but they must be ai-net. I thought all cd changers were ai-net, I have a CHA-1214, and want 2 more to give me 36 disks, is this going to work?
