About this product
The FX4 is a 4-channel car amplifier from the DS18 FX series, built as a Class D design. It delivers 4 x 180 watts RMS at 4 ohms. Total harmonic distortion is rated at 0.15% with a signal-to-noise ratio of 87dB. A selectable LPF/HPF/FULL crossover covers 40Hz-2KHz, so you can send each channel only the frequencies it should reproduce. Bass boost is adjustable from 0~12dB centered between 50Hz. Marine-grade construction makes it suitable for boats, side-by-sides and powersports vehicles. Match the amplifier to the RMS rating of your speakers or subwoofers and set the gain to that rating for clean, reliable output.
Features
4 x 180W RMS 4-Channel Amplifier
Delivers 4 x 180 watts RMS at 4 ohms. Power scales as impedance drops, so check the rating at the impedance you plan to run before matching speakers.
Class D Car Amplifier Design
A Class D topology runs cooler and draws less current than a conventional amplifier at the same output, with rated efficiency of 79%. That means less strain on your electrical system and a smaller chassis for the same power.
Marine-Grade Amplifier
Marine-grade construction protects the amplifier from water, spray and humidity in open-air installs. Mount it where a standard car amplifier would not survive.
Adjustable Crossover and Bass Boost
Onboard tuning includes a selectable LPF/HPF/FULL crossover covering 40Hz-2KHz and bass boost adjustable from 0~12dB centered between 50Hz. Send each channel only the frequencies it should play and dial in the low end without adding an external processor.
Protection Circuitry and Cooling
Built with thermal, over-load, dc output and short circuit output protection, so the amplifier shuts itself down before a wiring fault, a short or overheating can damage it or your speakers. That is what keeps 4-channel amplifiers alive in daily-driven vehicles.
