Really in my eyes, as long as you have the right ammount of space it shouldnt matter what you do. The only advantages to having a seperate chamber for each woofer would be if you only wanted to run one sub if something happened, and to strengthen the box up a bit more...

P.S- get rid of those as soon as you can, I almost blew up a set getting like 500-700 a piece, they were horrible they started ticking and making all kinds of horrible noises. Glad they saw the wall socket, not trying to bash them or anything but that is just my personal experiences.
