Hi im having problems with the road map of lines.  In step six on the WO plans(hopefully somebody has the plans in their head and doesn't have to look them up) my X is about an inch lower than it should be, i had this same problem on the other one i built.  Am I measuring something wrong, my box will be 28x36 when im done, does that have something to do with it not being right?  The first one i built hits hard and loud(135.6 in qualifing at db drag i played the stupid wrong track at comp so it might be a little louder but thats what i got so far), just want to make sure im not losing some performance from my error.  Any help would be greatly apperciated.

Thanks for the help glad i didn't screw it up to bad then.  I guess this box is very forgiving after measuring out everything and then comparing it to my other one which i placed the boards on the wrong side of the lines(doh) it still sounds great, i can easily keep up with other systems running 15s and 2400 watts in a ported box with my 12s and about 300 watts going to them.  hopefully getting this new box made right it will work better .  Thanks again
