hey I go a design from a local guy here, and just wanting to see what everyone thinks of it. I don't have alot of knowledge when it comes to custom boxes so I don't know if this makes sense or not.
The box is for 2 SA 12's and its going in the trunk of a dodge neon, so space is limited. I wanted to do the sub firing back because with my past setups, they have been noticeably louder than firing towards the front of the car. He suggested firing the sub back and port forward, I haven't seen many setups like that so I'm not sure if its a good idea or not.
I wanted to do two separate boxes, because I figured it would be easier to get them in the trunk as the trunk opening is more of a limiting factor than the trunk itself. he came up with a box size of14x14x23.5 tuned to 34hz.
these are pics of the design he sent:
