Goal is to install an amp that fits in the same location. If possible, I'd like to get an idea of how much room there is to work with before disassembly. Has anyone installed an aftermarket 5 channel amp here?
Edit: I already have a new head unit (Kenwood DMX906S and swapped out the front woofers and tweeters with components. Just need to know the size of an amp that would fit in the stock location.

I just replaced my sub with an older model Pioneer. It's definitely an upgrade over the stock JBL, but nothing too crazy. I purchased it a few weeks ago for about $100. There are newer subs by Pioneer, Rockford Fosgate, and Kicker that handle more power, but are more expensive.
You said you upgraded your speakers to components. Are they 2 ohm or 4 ohm? Did you replace the rear door speakers as well?
I recommend spending some time on
Crutchfield to get an idea of what amp fits. I believe the
Kenwood Excelon X802-5 will fit the factory location. It puts out 50 watts RMS x 4 + 300 watts x 1 at 4 ohms. My sub is only rated for 150 watts RMS and i don't want to blow it. Wish I would have thought of that before buying the sub.
I'm likely going to replace the factory JBL amp with a
JL Audio JD400/4. Though it's only a 4 channel amp, I plan on running 4 speakers and the sub. I won't have front to rear fade, but I already lost that when replacing the factory headunit. I'll end up with 50 watts to each speaker and 200 watts to my sub.
