If you really want to become a top notch box builder buy a few books on the subject. There are plenty of them out there. Myself, I am happy with my Subzero sealed boxes so I have never even attempted to build a box.

Regarding your situation with the 8s, my advice would be to run them in your doors and use them as midbass drivers (60hz-175hz or 200hz) and get something bigger to use as subs.

How many of these 8s do you have?? I have seen people with 4 to 8 8s set up and using them to cover 60hz and below and it sounded good, but the enclosure they were using is nothing for a rookie box builder to try to make. Trying to attain big bass with 1 or 2 8s might be kinda difficult...not that it's impossible...maybe someone else knows of a way to do it, cause I don't. I have never really looked into it that far either.

Hope that helps. Sorry I could not come up with any hard answers for you. Good luck.
