right box for my solobaric

[lowridin]

hello! i have an S15L7 solobaric in my trunk....i'm planning to replace my box cause my current box has many divisions inside...is it advisble to make a simple box enclosure or any design which is exactly fitted for my sub where i can maximize its performance.it's being driven by soundstream picasso 1.400 mono amp...any suggestions guys:confused:...i think my sub can't perform well maybe its because of my box design, so what is the best for it.?

i want my trunk to have at least enough space so i can still get my spare tire under the box:)

I can do a design for one but you or someone else will have to build it.
