Honestly, get a pro to do it. For about a 100 bucks, you could get a pro cabinet maker to make you the best looking sub enclosure around. Look for someone that does side jobs and ask them. Most of the time they will have extra wood lying around the shop from other jobs and they will use that, thus you don't have to pay for wood. If you went to home depot and bougth all the wood, screws, tools etc, you'd spend a lot more than if you gave a pro 100- 150 bucks to make something that will last forever. just make accurate plans and look someone up.
