I've climbed back there and can clearly identify sound from the green speakers but not the red one.
 
I will have to listen closer. Didn’t really differentiate between the two. I checked the other day to see if there was any base back there cause you clearly cannot hear it from the front. When open I can definitely hear base coming from that area, but it’s certainly not loud But I don’t know if it’s one or both speakers.

I tested the system today with a Bass Test on Spotify. Front seats sound good. Second row is pretty good and it feels like some sub from the fake larger speaker in door. Not sure if it is coming from there or not. Not very much. I tested the back lift gate door and felt it but it is very faint. Treble at 0 Mids at say +2 and bass at +3-4. But Bass in lift gate in Red above is not strong at all. Very faint to the feel. Again with Bass test. I can’t say it’s not working, but if nothing much w bass test, other songs have nada. It is faint. Like others have experienced. But it works.

Hi, I'm color challenged, but I just checked, and I hear sound from the 2 smaller speakers, but nothing from the larger bottom left speaker. Am I right that is the bass speaker? Or could it just be a port cover of some sort, with the other two being the bass?

That is the bass speaker, the other two smaller ones are 2 way speakers.

Then mine isn't working either, at least on what I've been testing. I will put it on my list of things to have checked. The first one actually, so that is ok compared to some vehicles I've had. Does anyone know what the issue is on this, and what the fix is?

I don't think anyone has had it identified yet, but if we look at the historical issues with ML systems, either the amplifier is defective/failing or the speaker itself is a dud.

You can try a test track with very low frequencies to physically feel if it's working like this:
