HK FEEL 700 is a first for Harman Kardon addressing the growing demand for adding more impactful bass to an existing in vehicle audio system. It produces deep, powerful bass while taking up minimal space and can be easily placed under a vehicle seat. The built-in Class D, 125Watts RMS amplifier is coupled with a die-cast aluminum enclosure, wrapped automotive grade fabric, allowing the FEEL 700 to offer a smaller subwoofer enclosure that augments the bass in factory audio systems. A fully variable crossover and Bass EQ are on-board to tune the FEEL 700 on your system.
