thunder 9500 sub box

[Festes40 10+ year member]

I have a thunder 9500 12" dual 4 ohm sub. I'm new to this, so any help will be appreciated....I need to build a sub box, something basic, probably a sealed box. I'm not sure how to go about it, dimensions, material, etc.... maybe a diagram of how to build it etc...I'm just looking for a clear, crisp, deep base....Thanks in advanced!
