Have decided to do some work with the boot. Removed the Sub box after disconneting the amp and cables.
The boot goes a fair way back under the rear parcel shelf so I am thinking of using the space for storage, jack, tools etc.
Mocked up a false floor and worked out what angles to use. Still striking some problems with the fuel tank filler tube. Need to work out if the side panels are going to be vertical or slope in toward the wheel recess.
This is close to what I have in mind,
Other than using the sides of the boot for storage (limited in size) I also like the idea of the exposed spare wheel. I still need some room for a smaller single sub box as the twin 10" subs will get the flick. Any suggestions welcome.
