Features & Benefits

Compatible Vehicle Fitment Universal
Subwoofer Terminal Type Push & insert style terminals for easy installation.
Subwoofer Configuration Round
Subwoofer Surround / Cone Coupling The pressure treated double stitched foam surround along with the dual poly cotton spider helps keep the piston motion of the subwoofer linear and distortion free.
Subwoofer ​Voice Coil / Former Assembly Vented aluminum former holds a 3″ voice coil while allowing the heat to be exchanged. (Less heat means less distortion)
Subwoofer Spider Specialized Hifonics dual poly cotton spider with double centering allows the woofer to handle more power with minimum distortions.
Subwoofer Frame / Venting Hifonics heavy duty aluminum die-cast basket allows back venting, which exchanges heat with cool air, resulting in more power handling and increased reliability.
Subwoofer Motor Vented high energy motor assembly with heavy duty magnets increases power handling and increases SPL.
Amp RCA Inputs Nickel Plated: High temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant.
Amp Operation Mode 1 Channel operation
Amp Crossover Type Variable electronic crossovers allow for complete control of the sound.
Amp Heat Sink Heavy duty heat-sink efficiently moves heat from the MOSFET where it can be cooled.
Amp Power Supply Rugged MOSFET Pulse Width Modulation power supply: Allows amplifier to product efficient power without taxing the vehicle electrical system.
Amp Output Connections Heavy duty connections allow for secure electrical signal to pass into wiring and resist erosion which will add longevity to the amplifier.
Amp Connection Type Secure connection for all power, ground, and speaker connections.
Amp LED System Protection Circuitry Diagnostics Monitor overload and speaker short protection with illuminated indicators on the amplifier panel.
Amp Bass Remote Included Included. This allows the driver to make subtle changes to the bass response of the audio system from the seated listening position.
