Harmony HR 6 US P — 6.5"/165 mm High-Power Underseat Amplified Subwoofer | HF Audio

Harmony HR 6" high-power underseat active sub. Maximum convenience, Italian bass.

The integrated high-power amplifier drives the 6.5" driver in a tuned enclosure optimized for underseat dimensions. Plug-and-play RCA or high-level input connection. No external amplifier, no custom box, no trunk space consumed. The right bass solution for vehicles where cargo space is at a premium and OEM-clean aesthetics matter. A complete self-contained Italian bass upgrade.
