Compact Footprint. Powerful Bass.

Don't let its size fool you. The SoundQubed HDB2.2-8D4 packs 400 watts RMS and 800 watts peak power handling into a versatile 8-inch subwoofer designed for custom car audio systems.

The HDB2.2-8D4 is an excellent option for installations where a smaller subwoofer diameter is preferred without giving up substantial bass capability. Its 2-inch dual voice coil design supports flexible amplifier matching, while the compact 8-inch platform is well suited for a wide variety of aftermarket audio upgrades.

Featuring dual 4-ohm voice coils, a single subwoofer can be configured for 2-ohm or 8-ohm operation.
