dont ever mention a brahma and a cheap box in the same post,thread, sentance again...why would you spend so much on a good sub and kill it with a bad box....its like renting a Mclaren F1 (if you really could) and not opting to spend 5 bucks for the insurance...
take the time and build a nice ported one.. its always nice to get that extra bit of spl especially with a 15.. i always take the easy way out myself with a sealed lol and always wish i had made a ported..
