im building a wall for 4 xcon 18s ill have about 27 cu ft. and i want to do 2 ports on each side any ideas

You could make each port 125 sq. inches and 19" long. That'll give you about 23 cubes after displacement tuned to 32 hz. I think ideally you'd want more room, but that may work.

i know im going to try to get as much box as i can but would i be able to just make the ports square or would i have to turn it anywhere?

in building a wall in a blazer for 4 xcon 18s and im putting 2 ports. i have about 32 cu ft. im going to run 2 soundstream 10,000s rms 7,500 and can i just build the ports square or so i need to turn it?

omghi2u!!1

as i say to others, put a bit more effort into making an interchangable port system and then fine tuning playing with lengths to get the best result.

well the only reason i have to do 2 ports is because i dont have enough room for 1 big port but i can put 2 because my box will be bigger at the top then on the bottom because my wheel wells

That obviously depends on the depth of your box.

Why did you create basically the same topic in the newbie sign in forum after this one?

Merged.

is this for a tahoe/blazer i'm assuming? Welcome to the site!

no its in a regular 4 door blazer. the box can be 34 in deep
