Our take on the FRP Compact 4-Channel Full-Range Class-D Amplifier

The DS18 FRP-2.4K4 is a compact four-channel Class-D car amplifier rated at up to 2400W RMS. It is stable at 1 ohm per channel or 2 ohms bridged, so it can drive mids, highs or subwoofers from one small chassis. Adjustable high-pass, low-pass and full-range crossovers plus up to 12dB of bass boost at 50Hz give it more tuning than most amps at this size. It suits people building a loud, space-conscious system who want one amp to cover the whole range.

Best forSpace-limited builds needing big four-channel outputRunning front and rear speakers plus a sub from one amp1-ohm or 2-ohm bridged low-impedance setupsDrivers who want onboard crossover and bass-boost tuning
Pros
  • High RMS output in a compact footprint
  • Stable at 1 ohm per channel and 2 ohms bridged
  • Adjustable HPF, LPF and full-range crossover modes
  • Up to 12dB bass boost at 50Hz
  • Class-D efficiency with a smart cooling fan
  • Tiffany-style RCA inputs for a secure, low-noise connection
Cons
  • 2400W RMS is a peak-system figure; real per-channel output depends on impedance and supply
  • Bass boost at a fixed 50Hz can muddy some setups
  • Fan cooling adds a noise source some owners notice
  • Compact chassis means tight terminals and less room for thick wiring

About the FRP Compact 4-Channel Full-Range Class-D Amplifier

The DS18 FRP-2.4K4 is a compact 4-channel full-range Class-D amplifier rated at 2400W RMS. It builds on the FRP-1.2K4 with more power and headroom in the same compact footprint. It can drive mids, highs, or subs.

It is stable at 1 ohm per channel or 2 ohm bridged. The crossover is fully adjustable, with HPF, LPF, and full-range options, and up to 12dB of bass boost at 50Hz. A smart cooling fan and surface-mount technology help keep performance steady at high output.

The digital Class-D layout is designed for efficient output, and the Tiffany-style RCA inputs help keep noise low.

Questions and answers

How much power does the FRP-2.4K4 actually make?
DS18 rates it at up to 2400W RMS total. Per-channel output depends on impedance and your electrical supply, so expect the full figure only in a strong 1-ohm or bridged configuration.
Can it run subwoofers and door speakers at the same time?
Yes. Each channel has its own crossover settings, so you can run the front and rear channels full range or high-passed and bridge the rear pair for a sub.
What impedance loads does it support?
It is stable at 1 ohm per channel and at 2 ohms bridged. Check your speakers' final impedance before wiring.
Does it have a bass boost?
Yes, up to 12dB at 50Hz. It is a fixed-frequency boost, so use it sparingly if your sub already plays low.
How does it differ from the FRP-1.2K4?
It uses the same compact footprint but roughly doubles the power, giving more headroom for loud full-range systems.
Where is the FRP Compact 4-Channel Full-Range Class-D Amplifier cheapest?
At Elite Auto Gear, for $279.96, 20% under what the other stores charge, as of our latest check.
Where can I buy the FRP Compact 4-Channel Full-Range Class-D Amplifier?
