right, the way speakers resonate is common sense to me to, however there is SOOOO much more to speakers than getting the phase and imagine correct (as I'm sure you know). Based on the Thiele-Small parameters you can determine what type of enclosure a given woofer will sound good in b4 you cut the first piece of MDF. It's really amazing to think how much speaker technology has come along in the past 15 years. When I was first getting started a guy by the name of Mark Fukuda held the world record in SPL w/ a 153.6 in a bright yellow 1989 Chevy S10 Blazer (one of the cleanest installs I have seen to date actually). Now, just about anyone can go out and buy a system that will be in the 150's for SPL for minimal money, and to really compete for a world record (unlimited power class) you need to be able to get into the HIGH 170's if not 180's dB. The point I'm getting at here is that with the advances in technology of the past 10 years there are literally hundreds of resources available to help you build and design a kick ass stereo system. My favorites are the Loudspeaker Design Cookbook, LEAP enclosure modeling software from LinearX, LMS from LinearX, and my Mobile Dynamics coursework books.
Another tip for those of you contemplating competition (non-SPL) is use the least amount of speakers you can for sound quality. A good pair of 6 1/2" coaxials in the kickpanels and a pair of tens in a sealed enlcosure in the trunk might win you more than you'd ever imagine.
