i went crazy a bought a cerwin vega stroker 124. this thing has 2000/4000 watts thats crazy. its massive and i can tell its gonna want a lot of space, its going to be by itself so that wont be a problem...but i hear vega's are very picky and i dont want to screw this up. iv came across some incredible responses throughout this site and would greatly appreciate some dimensions to build a box for a 02 chevy impala. just the one 12, but how much space should i give it? it says the mounting depth is 8" and mounting diameter is 13.125. so am i supposed to cut a circle exactly that big for a perfect fit, or is that the exact diameter of the speaker itself? how big should my ports be, should there be more than one port... for security reasons, and to help the rattle, id rather face the speaker toward the back seat instead of out into the trunk. facing the box at an angle would be cool. but im a first timer on this and knowing how vega's are....i want to do this right the first time. any and all responses would be greatly appreciated.
