here’s a design of my box

Sub where yellow is correct. But I don't like the port opening out the side. I had a box design similar to that before but my ports opened out the front next to the sub. What is this going in?, I can't remember.

Jeepers that's a big port.  Do you need 50 square inches of opening?  What are you pushing to this sub...a thousand watts?Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Lol, the sub is a W7 and the amp is the 500/1. Its going in a 2001 Eclipse. Im impatient when it comes to new stuff for my car, so I already got the wood all cut at Home Depot. They did a pretty cool job, the person that cut it for me measured it before and after he cut the mdf. It roughly cost around $29. I know it should've cost more, but it was closing time and the person who cut it didnt write out a receipt or anything. I did forget to pick up some wood glue, but I wanted to know if there was anything you guys would recommend. I know not to use liquid nails cause Ive been doing a little research and I read on alot of sites saying not to use it.
