UCLAMDX,
I completely replaced the factory system in my base model. The amp for the subwoofer on the base model is actually behind the factory subwoofer just over the rear wheel. Anyway, I actually put my amps where the headrests are stored (of course you loose the headrest storage).
If you do a search on my posts I posted some photos of the work we did.
The Alpine 5 channel might work real well for you and be of a resonable cost. Make sure you replce the factory sub with one that can handle an "open air" enclosure or have a box built or the sub will "fart" all the time and never sound as good as it could.
If you go with amps that can handle "high-level" inputs you will be able to use the input from the factory radio to drive the amp which would save you some money and trouble. I don't know if the Alpine does this but you can also get converters that convert high-level speaker output to line level RCA. You can feel free to put almost any aftermarket radio you want (that fits of course) but the installers have to make a custom install kit as nobody makes a kit for the MDX yet.
I would replace the factory speakers with ones that please your ears and can handle the power of your new amp. I will never make an suggestions as to which speakers you should get as speakers are a very subjective item.
Let me know if I can help with any specific questions. We had my MDX interior torn apart and I know it well.
