Should i give them each seperate ports? Ive read that one large port on the side is more efficent.

If they share a chamber then they have to share the port.

If they have seperate chambers then they must have seperate ports.

If they share a chamber then they have to share the port.If they have seperate chambers then they must have seperate ports.

Which is better for my application? I KNOW all the specs and stuff for one ported sub, so its really easy for me to give them all a seperate chambler and port, but if the other way is better i wouldnt know how to go about doing that. Sizes and such.

You have said nothin of your application........

What vehicle?

Is it a wall?

Is it a trunk?

In a truck?

Blowthrough?

Its a 1990 audi 100, and it will be ing the trunk. I not sure if im thinking of the right thing with "blowthrough" but in the back seat it has a arm rest that comes down in the middle with access to the trunk. I cut out the ski sleeves so its just a straight hole to the trunk. If your talking about aiming the port through there, it looks like more trouble than it would worth.
