BTW ratio doesn't mean anything, it's just a guideline....individual volumes matter, not the ratio.

I agree with this^^^

Volumes look like their on point too and a good baseline for where I'd start too.

I'm in process of designing a bandpass 4th wall for 4 15" XLs.

Im not the one you want to try to troll. Just a fyi for you.

I think what he has John, is a box with 3 chambers. A sealed chamber on each side and the subs firing into the common ported chamber. He's running a blowthrough so I'm going to guess he just had a single port into the cabin. He's got a blowthrough in a Honda Ridgeline I believe.

So build is in full force! Using 3/4 inch birch x 2 screwed and glued together. Baffles will be 4 layers screwed and glued together! Btw I have not been able to post pics in a long,long time. Is there some kind of settings on my computer that might have changed? And I usually use photobucket to upload pics

You could try uploading the pics to imgur.com. Photobucket was a great service years ago, but many sites are more convenient nowadays.
