The prompt

Create a solid box with a width of 300mm, a height of 300mm, and a depth of 320mm. Shell the box inward to create a hollow interior with a uniform wall thickness of 18mm. Select the front face. Draw a circle with a diameter of 185mm, centered perfectly both horizontally and vertically on the face. Extrude-cut this circle entirely through the front wall to create the subwoofer driver hole. Select the rear face. Draw a rectangle that is 150mm wide and 150mm high, centered horizontally and positioned 40mm from the bottom edge. Extrude-cut this rectangle entirely through the rear wall for the amplifier plate.
