im going to say you will probably be better off going with a monoblock amp for the subs, and a multi-channel for the speakers.
im running a JBL GTO601.1 for my subs right now. it great, internally bridged, so no complicated wiring, and of course lots of power to play with
im just running my interior speakers off the built in poweramp in my HU, (it has a 200W rating (probably not RMS though) but that works good for now.) so i can't really suggest a multi-channel amp, but definatly look into JBL. amazing quality
