I think I might have made the front of my box too short. I didn't even realize it until after I had it all cut, because if I made it much longer it wasn't going to fit in my trunk. Well, here are some dimensions.
The sub cutouts are 11", the subs actual width is 12.3 inches, the box itself it a total 52" long. This will give ~2.5 inches of space inbetween each hole of the subs.
Do you think that 2.6" will be enough space inbetween the subs that they wont break? The subs are Tidal Audio 12s (ID OEMs), and are going to be getting ~300 watts each...
I accidently posted this in the wrong section the first time.
