Alpine Type R Box size

I picked up a sealed box and it measures out to be about .73 cu ft. looking to put an Alpine type r 12 in it. According to Alpine specs, this box should be ok. Gonna be pushing it with a kicker 600.1 amp, Just looking for other peoples thoughts and opinions if this will be ok

 

that box is a little on the small size for the 1243d which is which one im assuming youre planning on getting (2ohm). if you want the best sound, you will need a slightly larger box or a more powerful amp. (in a smaller box like this, it will be harder to move the woofer cone; more power will be needed to get the right sound.)
