Another update, here is what my boot looked like not very practical,
got myself some MDF about 6-8mm thick and cut it to the shape of the old carpet it comes standard with and got a sub cover.
I cut up a 3x4 size plank of wood to make feet for the mdf to raise it off the amps, 5 feet in total one being a long one to sit bottom left corner.
Ordered myself a 200x200mm 6mm thick clear window (not glass),
lined it up marked and masked up and cut out for it to slot into,
with that done i got my self some mirror corners from b and q, fitted them so my window can slot in and rest on them,
no glue needed and can be replaced when scratched etc.
With that done i ordered alot of carpet so i can redo both the sub box, floor and sides to match, any colour difference would of been awful.
I removed both the plate, and boot latch, so i could carpet under them, i refitted them both after.
Ignore the staple around the window they were just there to hold the tension while the glue set, all removed now.
Anyway thats all, i got enough carpet to do fix any errors, i got a horrible bit on my boot lip so might redo that section at some time, also got to do the wheel cage locking nut, i cut out a mfd square to make a flap that i can hinge to give access, got some lights coming so will update once they have turned up,
then im on the look out for a JBL sub to replace the one i have, mines 620watts, looking at JBL 1000watt to complete my full JBL sound system, thanks for looking.
