Help in designing a box for 12" JBL sub

[pbcnx]

My friend is giving me his 2pcs 12" JBL subs.

Nakabox na siya. Pero i have doubts kung kasya ito sa trunk ko. So i want to redesign a vented box (for more boom) na kasya sa trunk ng lancer EL 1995 at para mabilis na makuha yung spare tire doon. If not possible yung vented, eh di sealed na lang...

Any suggestions mga car audio enthusiasts?

PS: What Amp can you recommend that could power these? (plus yung 4" seps ko sa front and if possible, yung 6" ko sa likod) :D

TIA

Ill be happy to help..You need to consider the size of your trunk..try to measure (In inches) from tire box-to-tire box(this will be your width) then the height (from floor to any metal above)..then ang depth niya..PM me if you work it out..

P.S. If want to have a speaker enclosure in your trunk accessing the spare tire is always a problem (only if you have dodgy tires that keeps blowing up).
