Hey guys, I just want to get some input on a burp box for 2 12" BL's fully loaded. This will be for a cross over and running 1000 or 2000 watts. Right now the system is up to 148.4 on 1800 watts with a some what music box. What I want to do is build the burp box so the subs are back and the port on the side. The info and input I need is the size of the box and the size of the port. Im 99% set on using a aeroport and was thinking 8" but would 8" be to small? Some people say the box needs to be big like 5 cubes and some say small like 3 cubes. So im a bit lost on where to start lol.
