how to make custom trunk enclosure??

well mine is done... but i want to redo it this time on my own cuz im getting a different system.. thus a diff setup....

how do they mornallly measure the size and shapes then cut out wood to perfectly place them in??? i looked at mine and it doesnt make sense...

not just that but then get the whole thing wrapped with like 1 sheet??? ( k well im exagerating... but u know what i mean... )

any close up pics of trunk enclosures or how to's???

i have 2 12" subs
2 amps
1 cap
and 1 lcd screen for the trunk....

maybe the battery.. not sure yet tho.... thanks guys and gurls...
