Thanks im going to double check what i did wrong. And do you think its a good box for 2 15 besides how come side 1 and side 2 are different is that where the double baffle comes into play

You picked a lower than recommended tuning (of 35Hz) and that's good for rap and the likes but maybe not so much for rock type of music. Here is an assembly diagram (generic dimensions):

Sides are different because of the assembly style.
