Is there something you want to gain by switching to a Monsoon amp? I don't get what there is to gain - the Bose system is designed to be an integrated system and the components are matched together. I assume the Monsoon system would be the same way. Mixing and matching components from two different systems that were designed as a matched set, makes no sense to me.
If you just want a different amp, why not replace it with an aftermarket amp? It would probably be easier to find. Also, you ask about speakers, if you are going that route, you are clearly breaking up the matched set. There is no need to stay with the amp.
My personal approach is to replace the speakers with more durable and higher power components and add aftermarket power amps with passive equalizers (one in front and on in the rear). I will characterize the system for a flat response curve with the equalizers (similar to what you do with a home stereo and EQ with a spectrum analyzer). Or even tailor the sound to my personal taste. The Bose system was designed essentially the same way but the EQ characterization of the system was built directly into the amp. There is a fancy aftermarket black box for several hundred dollars that is specifically designed to be able to do what I just described (I don't recall the brand but I saw it mentioned in this forum several months ago).
Since the EQs are to characterize the entire system, I don't need to have them mounted in a place that I'll have easy access to them (since I wouldn't change them anyway) and that avoids making it look like a hack job under the dash. It also keeps the factory look because I will still have the OEM head unit.
I am in the middle of this process right now with the Bonneville, I did this with my '92 LeSabre and was VERY happy with the results. I had several favorable comments about the audio system.
FYI - I am also integrating an iPod adapter and a bluetooth hands free phone into the system. It will automatically mute the radio / iPod when operating the phone, use the microphone in the rear view mirror and still work with OnStar fully functional (as I allude to in my signature).
