It looks nice, but why is it so big? Just to fill space out, or are you planning on putting other goodies in there? Maybe a stealthy hideout for the amp?

Make that a whole hell of a lot louder, port one side and give the sub 3 cubes of air to play with.. it'll be much louder.

I bet it sounds good. My shop is an Alpine dealer and we rarely build sealed boxes for the type Rs. You planning on getting two more soon?

DON'T mount your amp on top of your sub box. EVER. It's not good for the amp, the vibrations from the sub will eventually rattle the amp apart. Go search on the forums for "mounting amp" and see what you get.
