Make a baffle that is say big enough to fit inside the box, but has a 12" cutout, cut that in half, and screw each half separately in the inside of the box, then redo another baffle to fit the 18" hole but enough to mount the sub on, then you will have a box

take baby steps, u cant do it all at once unless u have a roll of 100's big enough to choke a donkey

seems like alot of work jsut for something i wanted to do for fun. guess its a no go lol

Steve I don't know why but everytime I see your new paint I want a Dr. Pepper...... is this normal?

heres an analogy for you. running a high power stereo without a fuse is like having unprotected sex with that hot chick at the bar with the sketchy sexual history. Sure you may be fine and nothing happens but that one time something does happen you're fucked.

i dont want woofer broke like bass sound clip clip and voice coil overheat

cut a circle that has a diameter of 19". make the cut in that circle for your 12" woofer...place over the baffle. should work. This is why beauty panels are useless

You do know its almost a 5cu box when the 12" btl says 2.25 max. you're gonna be free-airing it bro..
