Default should i buld a single or double chamber box?

Im planning to build a custom box for my infinity 12s. I want to make it sealed but should I separate the two subs from eachother, or just leave it open? What impact does this have on the sound?

buld 2 sep chambers.... least thats my way of thinkin.. that way you have a nice stiff box.. so it wont flex much also if you build it big enuff for 2 and one dies... you run the risk of damaging the 2nd sub.... ive always built my double boxes as 2, im sure others will chime in their reasoning later on..

I say do it with two chambers. Like said above this will cause the box to not flex as much, and will save you money if one happens to shut off... It will also make it sound alot better because there isn't as much wide open space inside the box... You can get it closer to the right specs for the subs. Dual chambers will give you better SQ and SPL whichever you are looking for...

not to mention it'* a lot lighter to take 2 box out then 1 huge heavy box out.. and easier to get to your spare tire if needed by moving one box out then a dual.. and another benefit is you can put each box on each side and have the rear door open ( that goes to the trunk ) to make it louder and turn it into a half a$$ ported trunk box so you will hear the accuracy and louder.. the box itself will muffle the sound wave from a dual box as it blocks the opening.

This is the box that I just got... It is duel chamber... It was made custom for an 80'* camaro... But it fits perfectly in my car.




It looks like it was custom built for my car.

this one is still really heavy though because it made out of 1" wood.

I think i will buid seperate chambers. There doesn't seem to be a good reason not to. Also, my car doesn't have the removable panel in the trunk, will this reduce the bass output in the cab?

Always seperate subs when building boxes. I could go into the accoustics/physics but that hurts my head.
