Right now in the cougar i've got 2 15"s in separate sealed boxes. I've heard that just putting one of them into a bigger and ported box that it would be louder than both in sealed boxes as they are now. The problem is space, so if i did make a ported box, i'd only be able to fit one ported box into the trunk and not 2. Any suggestions on how i should use both speakers with one ported box? I'm thinking about just making a normal ported box to the speakers specs and mounting the second speaker face to face with the first one. If i did this kind of isobaric design worthwhile or how else could i use the 2 subs in one ported box?
Front speakers: Pioneer
