I wasn't planning on adding Aero ports to my box, but I'm trying to sell it on craigslist as a package, and just want it to be loud. It has 4 12" ID OEMs. They are in a 4 cube box right now, but I know loud sells, and if I can make it 2-3 dbs louder I would like to. I just want to sell it. It is about as loud as my RE SE 15s were, but don't hit the lows as well. Any help would be really cool. Thanks.
