Regular Cab S10 Box Enclosure

[geat]

I currently have one FI BL (fully loaded) with a sundown 1500 on it in my truck. Ive been thinking lately about adding another sub. The box I have in it now is 42Wx12.5Hx4x10. It is tuned to 32 hz, and is 1.2 cubes after all displacements. It only has 10.5 sq inches of port area (newbie design error). It peaked out at 137.1 with the stock alt and a dead cell in the battery on the TL at 38hz. I have since upgraded to an excessive amperage HO alternator and the big 3 done in 2/0. The new box im thinking of building is 52Wx12.5Hx4.5x10. It is 1.8 cubes before all displacements. Would two BL's be happy in this amount of air space? On the port what would be better, a single 3" or 4" firing out on the drivers side. Or multiple 3" ports firing out of the top center of the box, 2-3 of them. Here are some crappy drawings a drew up in 10 minutes.

port firing on the drivers side, like existing box

here is one of my truck for good measure

Guessing that they're 12's?

You'll want at least 2 4" aeroports. I don't know which side will be loudest to fire them.

With only 1.8 cubes before displacement and 1500w you're better to just do 1 sub (unless they're 10s?... even 10's 1 sub is probably better)

You're better to just do 1 sub and a good enclosure here I think.

1 good 10 in the right vented enclosure will be plenty loud

this is only 100 watts and a cheap 10wo so you can get a idea of what i mean
