The Boston System is actually quite a good system. Of course it's just my opinion, but I like the Boston system in the Commander better than most any factory premium stereo I've had. I've had two Bose systems, two Infinity systems, two JBL Pro systems and two generic premium systems, and put the Boston and the JBL up at the top.
The front sound stage is a component system. The 6x9 door speakers are low passed at the factory amp to act as subwoofers. I've heard the crossover is around 400hz, but it sounds lower than that to me; maybe 200hz. The dash speakers are 3.5" and crossed over with a high pass at the amplifier. The rear doors use 6.5" full range speakers with whizzer cone tweeters.
The Boston speakers are basic treated paper cone speakers, but they are well built. I found the clarity slightly lacking up front and especially in the rear doors, and opted to upgrade the speakers.
Mopar teamed with Kicker to make an aftermarket drop-in replacement set of speakers for the Commander as well as a drop-in replacement amp. Personally, I like the EQ of the factory amp, so I just changed out the speakers to the Kickers. These speakers require no special adapters or plugs as they are made specifically for our vehicles, so it's as simple as unplugging the old speakers and plugging these in. The new speakers are a composite cone with dome tweeters for the dash speakers and the rear doors. The front 6x9s are full cone, which you can't find in any aftermarket solution, so you'll get better bass response than your typical 2 or 3 way (generalizing).
Anyway, I found the Kicker drop in replacements to not only be incredibly easy and well integrated, but also matched impedence (2-ohm up front, 4ohm rear) to the original system and well paired to the Boston Acoustics amplifier. The clarity is improved as well as the clarity and smoothness of the bass. I also added a dynamat-type door kit at the same time which helped a lot as well.
If you want a little more bass in a clean package just to round out the lower end, I would recommend the Rockford Fosgate P300-10, following the Mopar-Kicker install documentation for the Kicker sub, which is no longer produced.
The part numbers for these upgrade speakers are 77KICK10 for the rear doors (well reviewed and popular for the wrangler) and 77KICK11 for the front soundstage. I highly recommend them for a really easy and well integrated upgrade to the already good Boston system.
All this information pertains to an inexpensive but significant upgrade in sound quality rather than ripping out everything and starting from scratch. If you do want to change your headunit as well, follow Mongo's advice. If you choose to not use the Boston Amp and don't upgrade to the Kicker amp either, you will want to use a dedicated component system up front and rewire it as the factory amp contains all the crossover circuitry.
