I know there is a car audio spot now but I thought this would be the best place for an answer. I just sold my 12" DVC to a guy I work with for his car, & I told him I would build him a box for it. I know I should know how to use WinSID by now but I just don't under stand the thing so please excuse my stupidity, Besides thats what the forum is for right? Anyway can someone help me out for a small sealed enclosure that would work well with this sub, or rather a pair, as he is ordering a second one. I'm thinking something that will play well in the 30 to 40hz range. If I went with something 14" by 14" square outside how much app depth would I need, I will be using 3/4 MDF board. I don't know if the input power will mean anything here but he will be using a (model #???) MTX amp that is rater at 360watts bridged into 4ohm, one for each speaker wired parallel. Thanks for any help.
