Harman Kardon Subwoofer Removal

Does anyone know how to remove the subwoofer and the enclosure from the vehicle? I have located the subwoofer and it’s in the trunk on the passenger side. There’s a storage area with a net there. Once you pull the storage area out, you can see the subwoofer and the enclosure. It seems like the lower bolts of the enclosure are not easy to get to and the opening made by pulling the storage area out isn’t large enough to pull out the subwoofer enclosure, so how do I remove it?

I removed them both and the low end volume increased significantly. I also ordered a new Center speaker as mine was making a buzzing sound at lower volume. I emailed Focal in France regarding the ICC MBZ 100 4" replacement and he stated it would fit my SUV. Its a 4" with a 4 ohm dual voice coil to retain music and the SOS feature. I can report on that as well, it seems like a 15 minute R/R task at the most. BTW, I bought some very nice/cheap trim removal tools at Harbor Freight last week. Excellent investment! More later as it develops.
