I made this today using Google Sketchbox. Just wondering what you guys think? It's 3.18 cubes gross and 2.59 cubes net. It's tuned to 33.23 hz with .75 inch MDF. I plan to put a 12" Havoc sub in there. The logos on the top I just made real quick. One is supposed to be AA and the other RF. They clearly don't look anything like the real thing but I just made them quick to see what it would look like. If you guys have any suggestions, please feel free to chime in. The Havoc specs are between 1.5 to 2.5 cubes so I thought this would be a good fit. It's going in a 2007 Denali.
