You definitely have the HiFi system, and that is an amp back there.
This document probably describes your system pretty well:

The HiFi speakers which your system (and mine) came with aren't that great. You can actually it a noticeable and worthy improvement in sound quality (if not loudness and dynamics) by upgrading just the front mids and tweeters.
There are a lot of paths you *can* take. The HiFi system in my opinion is the simplest to upgrade of any of the various audio packages. The head unit is coded such that the output is flat and unprocessed and its balanced signal type can be used by several amps on the market.
So what you do should be a function of what you want.
- What bugs you about the stock system
- What you'd like to get out of any upgrade
- What music is most important to you to sound right (Fifty Cent vs. Indigo Girls : )
- Your budget
- Your willingness to DIY (I'm guessing with that pic of the missing center speaker grille, you're willing : )
BTW, I hates the Focals, so you weren't reading my stuff.
