[QUOTE="SmartAsss, post: 7214392, member: 629857"] blocks of wood will help with the volume size, the above mentioned solutions are the opposite of what you need to do. those will actually make the box act even larger. You'll want to run winISD and find out what changes need to be made to the port. going from 1 ohm to 4ohm will give you a theoretical loss of 4db. It should be only slightly noticeable if at all. Your electrical system will thank you though. 500w divided by 12v = 41.66 amps 41.66 amps x 13.8v = 575w Too large of a box can be a good thing... if you have a sub sonic filter that is variable enough. just turn the filter way up until it sounds better. you can actually get really efficient and better sound quality by having too large of a box and the proper crossover settings. the head engineer at JBL actually recommended this on another forum.
