Full Range Means All Systems With DS18’s FRP-2.5K!
Its variable crossover filters allow you to fine-tune your sound for optimal performance. Depending on your Band-Pass Adjustments, this Full-Range Amplifier can be used for Bass, Mids, or Highs. Micro digital design maximizes the FRP-2.5K’s power output and efficiency.
DS18’s FRP-2.5K was built for durability and performance. The protective coating on the PCB prevents moisture corrosion and bonded components provide extra vibration protection. This means you can enjoy high-quality sound even in harsh conditions.
Its bass boost feature enhances your low-end frequencies for a richer, more powerful sound. The bass knob also comes with power and clip indicators: with short circuit thermal, DC offset, and high/low voltage protection - your amplifier and vehicle are safeguarded against the most common problems in car audio.
DS18’s FRP-2.5K outputs 700W RMS @ 4-Ohm; 1300W RMS @ 2-Ohm; 2500W RMS @ 1-Ohm; and 2800W RMS @ 1-Ohm (BURST) – perfect power settings to supercharge any vehicle.
Thanks to its compact size, Tiffany RCA Terminals, and coming in three different colors (blue, titanium, or red) the FRP-2.5K fits in any system.
Upgrade with DS18’s FRP-2.5K and bring power to any system.
