The wood is 13 ply baltic birch plywood treated with epoxy resin. The epoxy is expensive but far superior to polyster resin.I have alot of work to do but it is coming along.

Damn Beajay,Your car is unreal. looks like 160 just might be around the corner.

Ian, are you going to be at the show today @pulse car audio?

Ian, the new subs are looking good, i guess it was time for a change,beajay you car looks sic now too.

Hello everyone, This is my first post.I currently have 2 dd9518g dual 4 ohm subs,1 hifonics sampsom amp driving these subs in a 12 cft box ported to 35 hz with 140 sq in port. this system is in a 2007 chevy avalanche with the midgate removed.I currently hit a 149.5 db @ 47hz. I have 24 cft avaliable for a new enclosure for the new season and would like to try a bandpass box.This is a daily driver so i cant make any major mods to the truck.The truck have 2 layers of dynamat on the doors,roof floors and bed of the truck.I currently have a dual alternator setup with 6 kinetik hc1800 batteries for a electrical system.Believe it or not i also use this vehicle for sq also.I am wondering if anyone could point me in the right direction for the new build and design.

My front stage is a 3 way setup using DLS irdirium 6.3 using a jl audio 450.4 v2.

Bandpass enclosures can be very loud when tuned properly.alot of db drag vehicles in Europe use bandpass enclosure and have great sucess. I currently run 1 hifonics Samson amp at 1 ohm (8000 watts).

I have 12 cft total for the subs

Hello, I currently have 2 15" q series dual 2 ohm with the b/p option .I'm running these subs in a sealed enclosure and would like to try them in a ported enclosure of 4 cft tuned to 30 hz .However, the FI Audio site doesn't tell you about port length only port area. I was hoping i might be able to receive some help here.
