first of all you'll prolly never run 200 rms on those tweets.just look for an amp that does 60-80 rms per channel and you should be fine,you can do 100 rms per channel and turn the gains down for the mtx speakers too, but the tweets will prolly drown them out.

I'm assuming I'll need a 4-channel amp?

How about this amp?

MTX Europe - RT404

or should I find one rated for 75w rms @ 4ohms?
