box help please

[steve c 10+ year member]

gentlemen,

currently i have two alpine type r12's in my 08 scion xb. They are powered by 2 alpine v-12 600w amps. The box that I am using is a store bought sealed piece of shit that really sounds like crap.

I'd like to venture into the spl world with my current set up. Obviously i need to use a ported box but I'm unsure of the cubic feet and port area required to achieve some "nice bass"

any suggestions would be greatly appreciated

the workspace dimensions:

20" depth

40" wide

16" height

Thanks

oh a picture of the current set up. the only difference is the amps are mounted in the c pillars

jesus i forgot how quick and dirty this site is... thanks guys...

just to make sure I'm not retarded 2.25 per chamber and a combine port area of 72" (36" per side)

Oh does anyone have a problem with this system firing up?

I don't think I have the room to face it towards the trunk lid

if you have room to fire them up then you have room to fire them back.
