What makes a subwoofer louder?

[bbeljefe]

So with upgrading seeming to be a no no, i got a dum idea. If the box had separate chambers, can i get 1 sub amp an battery @ a time? Hahaha i just had to ask....

My issuation is that il be building $2-400 @ a time. And in total il need about 2.5-3k. Shud i just be humble an save til Christmas?

With a dual chambered box you sacrifice internal volume due to the need for two ports and the partitioning wall. It isn't a lot of space but it is something that has to be considered. That said, if it works for you then do it.
