More about the product
The Kicker 51HS12 is a compact powered 12 inch subwoofer designed to add strong low frequency bass without taking up valuable boot space. It is built into a slim all aluminium enclosure that is designed to fit under many vehicle seats, making it a popular solution for modern cars, utes and SUVs where space is limited. The sealed metal housing also helps protect the subwoofer and amplifier while assisting with heat dissipation during extended use.
The Kicker 51HS12 features a built in amplifier rated at 230 watts RMS, providing a noticeable bass upgrade over factory audio systems. The 12 inch subwoofer delivers controlled low end performance across a frequency range of 25 to 120 Hz, adding depth and punch without overpowering the rest of the system. This makes the Kicker 51HS12 suitable for daily driving and a wide range of music styles rather than extreme competition setups.
Integration is a key strength of the Kicker 51HS12. It uses FIT+ fail safe integration technology, allowing it to accept both low level and high level input signals. Input sensitivity ranges from 250 mV to 10 V for low level signals and 1 V to 40 V for high level signals. This wide input range allows the subwoofer to connect directly to factory or aftermarket head units without the need for a separate line output converter. It is also compatible with modern vehicles that use start stop systems.
Tuning controls are built in to help tailor the bass output to the vehicle and personal preference. The Kicker 51HS12 includes an adjustable low pass crossover from 50 to 120 Hz, a high pass filter fixed at 25 Hz, a phase switch with 0 and 180 degree options, and KickEQ bass boost adjustable up to plus 6 dB at 40 Hz. A remote bass control is included, allowing bass level adjustment from the cabin without accessing the subwoofer.
Installation is designed to be straightforward. The Kicker 51HS12 includes a wiring harness with power, ground, speaker level input and remote turn on leads. The enclosure measures approximately 43.5 cm deep, 30.8 cm wide and 8.8 cm high, making it suitable for underseat placement in many vehicles. Overall, the Kicker 51HS12 offers a practical and tidy way to add real bass performance while keeping the interior clean and factory looking.
