About this product
The FRP-2.4K4/BL is a 4-channel car amplifier from the DS18 FRP series, built as a Class D design. It delivers 4 x 250 watts RMS at 4 ohms, 4 x 400 watts RMS at 2 ohms, 4 x 600 watts RMS at 1 ohms, 2 x 750 watts RMS at 2 ohms and 2 x 1000 watts RMS at 1 ohms. Total harmonic distortion is rated at 0.5% with a signal-to-noise ratio of 90dB. A selectable Yes, HPF/FULL/LPF crossover covers 10Hz-2KHz, so you can send each channel only the frequencies it should reproduce. Bass boost is adjustable from 0-12dB centered between 50Hz. A remote level control is included so you can adjust output from the driver seat. Match the amplifier to the RMS rating of your speakers or subwoofers and set the gain to that rating for clean, reliable output.

4 x 250W RMS 4-Channel Amplifier
Delivers 4 x 250 watts RMS at 4 ohms, 4 x 400 watts RMS at 2 ohms, 4 x 600 watts RMS at 1 ohms, 2 x 750 watts RMS at 2 ohms and 2 x 1000 watts RMS at 1 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 97%. That means less strain on your electrical system and a smaller chassis for the same power.
Adjustable Crossover and Bass Boost
Onboard tuning includes a selectable Yes, HPF/FULL/LPF crossover covering 10Hz-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.
0.5% THD and 90dB Signal-to-Noise
Total harmonic distortion of 0.5% and a signal-to-noise ratio of 90dB mean the amplifier reproduces the signal it is given instead of adding hiss and distortion of its own, which matters most at high volume.
