I want to put my two type R's in a ported box and need some help designing the box. I don't fully understand the tuning of the port fully. I am running an 1100watt Memphis at 1 ohm on each 15, so I should have enough power. Right now, they are in small sealed enclosures and I am wanting more performance out of them. Any help is greatly appreciated. I have the tools required to build the box, just not the experience. It is going in the back of a Tahoe, so I should have plenty of space. Oh yeah, I want two boxes. One for each 15, but they would be identical. I need to be able to remove the box from the truck by myself, so I don't think one large box with two 15's would allow me to do that. So I need two seperate boxes of identical design. Thanks.
