The idea is to have 2 10"s down firing with 2 4" aero ports firing up. The box is 3-3.2cubes tuned to 32-34Hz. It'll be a center console style box (ya I know, another one). The last on didn't quite work out due to lack of space for the sub. So I'm gonna try 2 10"s instead. Any input would be great, thx.
