Features
280W Maximum Power
Ensures robust audio.
Low-Noise Preamplifier Circuit
A maximum low-voltage signal from the source unit comes into the amplifier circuit with minimal distortion.
Nickel-Plated RCA Inputs
Erosion-resistant and high temperature impact-resistant with hex screw terminals that allow for secure connections.
Electronic Equalizer
Control of amplifier output with on-board electronic crossover to tailor specific frequencies to speakers and subwoofers.
Class SQ (Class D)
Offers the efficiency of today's D-Class with increased engineering to focus on sound quality from the power supply through the output devices, the FLUID-FETS.
FLUID-FETS
Painstakingly selected for their ability to efficiently produce power and mimic the sound quality of the highest-end home amplifiers.
Aluminum Heat Sink
Quickly dissipates heat to allow the amplifier to run lower impedance for longer duration.
Rugged MOSFET Pulse Width Modulation Power Supply
Allows the amplifier to produce efficient power without taxing the vehicle electrical system.
Heavy-Duty Connections
Allows a secure electrical signal to pass into wiring and resist erosion, which adds longevity to the amplifier.
Wired Bass Remote
Adjustments to bass frequencies can be made from the control mounted anywhere in the vehicle.
Auto Turn-On
The amplifier turns on when a signal is received on the RCA inputs, so an amplifier remote turn-on wire is not needed to turn on the amplifier.
0-9dB Bass Boost
Lets you add punchy bass to your music.
101dB Signal-to-Noise Ratio
Offers crisp sound.
0.09% THD (Total Harmonic Distortion)
Provides clean sound.
