Right now I am running a cheap box from ebay. Dual box sealed. Each side has 75^3ft in it and I know the subs need around .5^3 ft recommended by SD. For some reason I know I am not getting full use out of the Subs. I am running them with a sundown audio amp. SAE 1000d running at 1ohm to both speakers. I was hoping someone could point me in the right direction in getting full use of my subs and if anyone has any plans they could point me to. that would be greatly appreciated. If not i was going to modifty my box that i have now. Taking what i can to build a proper box. Thing is, the box is not a box its more of a trapezoid type box. That is where my confusion comes in when building one and getting the right amount of space for my subs. I just want to get the most use out of my subs because i love them!

The volume recommended by the manufacturer isn't what the subs have to have in order to perform, it's either the minimum for good performance or an average for good performance. By having your subs in a larger sealed volume you actually get better low end extension from them, although you'd get even better performance from a ported enclosure.

Also, how did you manage to install 10" woofers in a box made for 12s?
