ML System No Rear Bass Speaker

[Caiya]

I purchased the gx550 Overtrail plus with ML system in it. The first impression of the ML system is not worth the 1000+ price. My previous car was a Volvo xc60 with B&W speaker, it sounded absolutely amazing, but this ML is just so so. After driving for 4000 miles and I realized there’s no bass sound at the back. I also found the video other people taking the rear door panel off and this is what the bass speaker looks like. Lexus come on.

I wonder if we can swap out w a better speaker.

I also have no sound coming from the bottom set of speakers in the rear doors. I have the lux+.

What is that? It’s a speaker?

No audio from rear hatch speaker. Very dissapointed in this 1k upgrade.

Interesting. How are you testing this? I might want to have a look as well.

I listened to the front and rear bottom set of speakers. I also faded the sound from front to rear.

Update from dealership.
They removed the rear door panels and showed me the "dummy" speakers and said that all ML's were like this. The speaker map another forum member posted indicates otherwise.

So strange they'd put dummy speakers in. A simple cost cutting thing? Or maybe the dummy speakers there for a potential sound upgrade option in the future?

Actually the speaker map does show them empty.

Someone said those blanks are for the non ml system.

Lux+ owner here. There are blank plastic speaker hole fillers in the rear doors of the ML equipped GX550’s. Yes, the connector is plugged in, but has no power going to it, and the plastic piece appears to only serves as a place holder for the speaker, and perhaps to maintain some rigidity in the door. Interestingly, the two other door speakers are mounted to the actual door panel, and come off with it, when you remove it from the vehicle. I may attempt to splice into the larger of the two door speakers, to add a 6.5” speaker to the bottom of the door. Just not sure how or if the factory amp has that speaker’s lower frequencies tuned out…in that case, it wouldn’t help much to add another speaker back there.
And, the door panel just pulls straight off, once you remove one screw behind the door handle and two from behind the door pull. Pull straight off, no lifting up on the top of the panel. All secured with push in clips.
