i looked at moe lesters box plans but some of the pics are down,anyway i got a 99 grand prix and the box is for daily driving
36" wide,16" high,16" deep(i can go up to 20" deep but i prefer to keep it between 16 and 20 so i can have a little room in the trunk)im gonna be running 2 12"type r's(swr-1242d dual 4ohm) and i want it tuned to about 32 to 36hz i have read that about 2.3 cubes per chamber is good(or what ever i can get out of those dimensions).i was thinking of putting subs facing the rear of the car with a center slot facing the same way.i dont know if this would need bracing or not,but if it does i will brace it with some all thread.heres two links with specs for the speakers,i would like the bo to be similar to this one

I see something wrong: You fail to post links. You CANNOT copy a thread you have made somewhere else that includes links that have been shortened by the forum -- they will not work because of the "..." that gets added to the URL. If you want to copy/paste, you have to edit the post and then copy it from there.
