well the time has come for me to get some more bass so im going to run 3 AudioQue HDC3's on 3 hk401sx's..
i did some measuring and it seems like im working with 35"W 15"H 28"D (i dont think i can get a bigger box unless i build it in the trunk, cause i still need room for batteries and amps and crap)
with those specs the box will be 6.93 cu.ft. will that be all right for 3 12" hdc3's?
next, is birch the lightest wood? because weight is becoming an iusse? and how light is it? compared to MDF
