I thought I'd better update this....
I made a router jig for making my life easier on the sub boxes and everything else (will make an aluminium one shortly)
As no one has seen all 6 amps together (namely, the 4 x MRV-1507s together), I decided to size things up the boot (and make sure I wasn't dreaming! haha)
OK... test fit time
I like!!! I modelled the boot this way so I could see roughly what distance I have from the back seat to roughly where the amps are. That happens to be 500mm with a boot height clearance of 360mm (Petrol tank underneath raises the floor 50mm high under the parcel shelf... annoying!) and 845mmm (towers lean into each other... also not a good thing!). So (taking back seat angle into consideration) I have around 5 cubes of space for subs..... PLEEEEEENNTY!
:O What's this???
A 3rd Xmax???
Hmmm.... to 3... or NOT to 3
Oh.... and this here ^^^ holds a very interesting platform I have a brilliant idea for it.
OK... back to everyone else's install I go!!!
