Does anyone know the measurements for the left rear side of the X. Its raining outside so I started brainstorming what if I could put 2 X5 subwoofer boxes on the left and right sides. I'm removing the bluetooth module and oem amp when the weather gets better. I was wondering are the 2 sides equal in measurements to put the same box on the right and left.
