This is EXACTLY, dead on, what I want to do! http://www.youtube.com/watch?v=cbIB5ng1FRo

So i need to make my box about 3.2-3.3 cu. ft. and I should do a common chamber? Also, is there a site I can buy the aeroports from?

Right now I have a Rockfords Fosgate P1000.1bd so I'm hoping I can just throw another one of those in. Here is the dimensions of the box I have in there right now (I want it about the same size). Cutout Diameter: 11" Box Volume (Cubic Feet Per Chamber): 0.95 Mounting Depth: 5-3/4" Box Type: Custom Box Color: Black Fit Location: Under Rear Seat Box Finish: Texture Dimensions: Width 51" x Front Height 9-3/4" x Rear Height 7-1/4" x Depth 13-1/2" Material: MDF MDF Thickness: 5/8" I know some of that doesn't matter, but I just copied and pasted off ebay.

Whats up everyone, i'm new here and I'm really getting into car audio. Right now I have a 2004 Chevy Silverado that I threw 2 shallow P3 12's in. I really want something louder. I'm not quite ready to do a blow through, so I want my first build to be 4 Sundown SA-8's underneath the rear seat, facing the front. I want two 4" ports, one on each side. I'm extremely new to box building, but I learn very fast. I have a few questions, and I would also really appreciate some pointers & tips. Question #1: Since I want 4 subs with a port on each side of the box, am I going to need to put a center divider in the center of the box, so that I create two chambers, each with two subs and a 4" port? Question #2: The SA-8's recommended box volume is .5-.75 cu. ft. so should I simply take .5 and times it by four, giving me a 2 cu. ft. box volume for the 4 subs? That's all the questions I can think of...for now. Any tips or other help is GREATLY appreciated!! Thanks, Mike
