skar evl-65 d2

This is my first time using this program so I'm fairly new to how it works I'm looking to build a box that will hold 4 skar evl-65 d2's and 2 skar vx200-st tweeters something not to big I'm even considering a smaller build with just 2 6.5s and a tweeter if anyone can help me it would be a big help

I’ve got 3 sundown X8s and they are pretty loud for what they are. Not sure if u can but don’t go too small on your subs. I started with 2 8”s.  Suggestion: go the manufacturers max on cubic ft per sub
