Recommended box

For a sedan, one sub, 2,000 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.

At 2,000 W this example’s port will be noisy: air speed 119 ft/s, while the limit is 82 ft/s. It stays quiet up to about 940 W. Full power needs a port of at least 32.9 in², which means a bigger box than this example — size it in the designer.
