Car Subwoofer Guide: 8, 12 and 15-Inch Sizes

The right car subwoofer depends on available enclosure space, desired bass output, amplifier RMS power and the impedance your amplifier can support.

8-inch car subwoofers

An 8-inch subwoofer can provide strong bass where enclosure space is limited. The DARKAI CAM 8-inch 800-watt subwoofer is one compact option; confirm its RMS rating, mounting dimensions and final impedance before pairing an amplifier.

12-inch car subwoofers

A 12-inch subwoofer offers a useful balance of low-frequency output and practical enclosure size. Browse the DARKAI AV 12-inch 1200W dual 2-ohm subwoofer, the dual 4-ohm version and other 12-inch models.

15-inch car subwoofers

A 15-inch subwoofer is suited to builds with enough enclosure and electrical capacity for high output. Compare the DKI 15v2 1500W dual 2-ohm subwoofer with the dual 1-ohm model.

Match impedance and amplifier power

Dual voice coils can be wired to different final impedances. Use the subwoofer manufacturer wiring options and keep the final load within the amplifier specifications. Compare the amplifier RMS output at that impedance rather than relying on peak-power labels.
