Recommended box
For a sedan, one sub, 700 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

At 700 W this example’s port will be noisy: air speed 136 ft/s, while the limit is 82 ft/s. It stays quiet up to about 250 W. Full power needs a port of at least 16.5 in², which means a bigger box than this example — size it in the designer.
