ok this might sound really stupid, but i dont really know much about ported boxes, ive used only sealed boxes so far, BUT, i am about to construct my own ported box for some Kicker comp Vr 15" subs. ok, so, the speaker calls for a 3ft^3 ported box, i am making a box for 2, so could i make one big 6ft^3 box with one giant port, or do i have seperate them into 3ft^3 boxes with seperate ports? that probobly sounds extremely dumb, but if someone could help be that'd be sweet.thanks.

They can be in the same box.

You can do a common chamber as long as you do much internal bracing. I suggest "ALL THREAD" to help minimize flex. I always try to keep subs in seperate chambers for a few reasons

1. If a sub blows out or quits working, it wont affect the second driver.

2. Common chamber enclosures are not as rigid as chambered (or seperate) enclosures without much bracing and extra work.

3. If using 1 amplifier per sub, they MUST be perfectly matched if using a common chamber enclosure, otherwise you'll damage your subs and/ or get crappy sound.

4. If using a single 2 channel amplifier (wired in stereo), the drivers are recieving different signals at different times, thus causing some cancellation of one another. (left channel usually drives more bass than the right channel). This is where a "MIXED MONO" comes in handy.
