i've had four 8" subs sitting in my room for a while now, they are nothing special but still i thought i should be putting them in boxes. i was planning on making two boxes with two subs in them, made up a design for them as well. halfway through making them now, and i have seen a 12" Sony Xplod sub at supercheap auto for $99, now i am going to buy that and two 5" Panasonic speakers and put them in a box, but seperate them into two in the one enclosure (sorry, its hard 2 explain). anyone got any designs for something like that, and do you think it is a smart idea? i already have two 12inch subs, two 5" speakers, four tweeters and an amp in my sound system...
