Looking for help with a single type r 1243d in a single cab ram 1500 box can be up to 60 inch long, 17.5t, 13w at bottom and 8w at top, my son just wants bass, rap & country. It's a project for him & I. I've built a few over the years but it's gotten extra technical, thanks for any and all help. BTW ported sealed or vented just the hardest hitting for him, and I figured I'd let him use my 90"s Era punch 225.2 Trans Ana amp
