i like the way you think on the paint i dont think ima weld it... the car will be a daily driver until i get a new car then its just a toy!
i talked to super-stanny on termpro and he said they work amazing in 16cf for walls
plus im making the regular port for daily a bit on the small side hopfully that will keep the sub from bottoming out at lower frequencys
i still gotta figure out the best way to secure the walls to the bottom and top because it will be assembled in the car, im for sure using glue but to hold it until it dries? maybe use the angle screw thing on them so i can put the screws in on a angle and they sit flush.
