For a sedan, one sub, 500 W. It’s the same math as the designer’s step-by-step mode, where you can fit the box to your space, vehicle and amp and get plans, a cut sheet and DXF.
Sealed

| Port | 2 round ports Ø2 1/2″, 14 3/8″ long |

At 500 W this example’s port will be noisy: air speed 127 ft/s, while the limit is 82 ft/s. It stays quiet up to about 200 W. Full power needs a port of at least 15.4 in², which means a bigger box than this example — size it in the designer.
