I have never built a box but I'm pretty handy with a saw. I will pay the right person to design a box for me. I'm not tryin to do anything off the wall, just a box for 4 15's. I want the subs firing up and the port to be at the bottom of the rear of the box firing towards the rear of my car. I also wanna make this box dual chambered so that I can just have 2 subs on at a time when just daily driving. I had talked with Buck about designing a box, but for some reason I cant get ahold of him. I am off Sunday and Monday and was kinda hoping to do this build on those days. If there is anyone that can help please let me know. Again I WILL PAY for the right design. PM me!
