The KICKER® Solo-Baric® L7S™ is based on the groundbreaking original square subwoofer. Massive power handling and more cone area means you move more air, and get more bass.


The patented ribbed corners on the Solo-Baric L7 Santoprene™ surrounds are constantly defeating distortion while adding control to make your bass loud AND clear – even with thousands of watts pumping through them.
Solo StrengthKICKER’s most advanced cone design, the injection-molded SoloKon™ adds 360-degree, constant-contact back bracing for a woofer that’s stronger, more reliable and incredible responsive.
Take The HeatThe cooler a sub is, the longer it’ll play. KICKER’s UniPlate™ back plate and pole piece are a single, solid unit, which allows heat to move away from the motor. Venting below the spider allows even more air to move, and heat to escape. Your subs play cool, as your music keeps bumping!

Low Noise Preamplifier Circuit Maximum low voltage signal from the source unit comes into the amplifier through a low voltage circuit which delivers minimal distortion through the amplification process. RCA Inputs Nickel plated RCA connectors for audiophile signal quality and maximum signal throughput with minimum distortion and maximum external noise rejection.
Electronic Equalizer Control of amplifier output with on board electronic crossover to tailor specific frequencies to speakers and subwoofers. Check specifications for specific frequencies for this amplifier.
Class / Topology Developed over 4 decades of engineering to deliver the highest level of sound quality and power efficiency, Hfioncis ALPHA Super D-Class® circuitry results in lower distortion, higher current efficiencies and while producing less heat than conventional amplifier designs.
Power Supply The Twin Turbo Coil PS is a Pulse Width Modulated power supply keeps voltage constant through the Ultra-Fi output devices.
Output Connections Nickel-plated, high temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant.
Connection Type Secure connection for all power, ground and speaker connections. Angled for ease of access during installation.
LED System Protection Circuitry Diagnostics Monitor overload and speaker short protection with illuminated indicators on the amplifier end panel.
Bass Remote Included HFR-31: Wired Bass Remote allows adjustments to bass frequencies from the control which can be mounted anywhere in the vehicle. Smooth potentiometer and ringed illumination in a satin black mount create a custom look.
Additional Features 300KHZ HIGH SPEED PULSING: The switching speed of the Class D chip puts the amplifier sampling frequencies at over 100 times higher than human ears can hear. This means that the amplifier and the very fast digital switching remains un-hearable in the audio bandwidth for music.
