Delivering exceptional power and unparalleled audio quality, DS18’s FRP-3.5K is the latest game-changer in car audio.

High efficiency micro digital design allows this compact amplifier to maximize its power output while minimizing its energy consumption. Its variable full crossover filters allow you to fine-tune your sound, for optimal performance tailored to your preferences. Depending on your Band-Pass Adjustments, this Full-Range Amplifier can be used for Bass, Mids, or Highs.

Engineered with advanced technology, the FRP-3.5K features surface mount component technology and Reliable Four Layer Trace PCB Design that enhances durability and performance. The protective coating on the PCB prevents moisture corrosion, while bonded components provide extra vibration protection. This means you can enjoy consistent, high-quality sound even in harsh conditions.

Equipped with power, protection, and clipping LED indicators: the FRP-3.5K provides real-time feedback on its status. You'll have peace of mind knowing that it features short circuit thermal, DC offset, and high/low voltage protection to safeguard both your amplifier and your vehicle.

DS18’s FRP-3.5K outputs 1000W RMS @ 4-Ohm; 2000W RMS @ 2-Ohm; 3500W RMS @ 1-Ohm; and 4000W RMS @ 1-Ohm (BURST) - perfect power settings to supercharge any vehicle.

Installation is a breeze thanks to the FRP-3.5K’s compact size and Tiffany RCA Terminals. Coming in three different colors (blue, titanium, or red) the FRP-3.5K will fit right into any system.

Upgrade with DS18’s FRP-3.5K and experience the DS18 Difference firsthand.

Due to the high amount of amperage required to fully power this amplifier, DS18 recommends the use of dual input power and ground terminals.
