Watch the DS18 FRP Dyno Tests See the FRP series tested on the dyno and get a closer look at the compact full-range amplifier platform. Full-Range Monoblock — Not Just for Bass The FRP series is designed as a full-range single-channel amplifier. That means it is not limited to conventional subwoofer duty. Depending on the crossover configuration and speaker system, an FRP amplifier can be used for bass, large mid-bass drivers, midrange arrays, or other high-output single-channel applications. Bass Systems Use the available crossover controls to configure the amplifier for properly matched subwoofer and low-frequency applications. Mid-Bass Systems High-output motorcycle builds can use full-range monoblock power for large saddlebag woofers and mid-bass arrays when correctly filtered. Pro-Audio Systems Full-range operation also provides flexibility for properly designed high-output midrange and pro-audio configurations. FRP-2.5K – 2500W RMS The FRP-2.5K is the smallest of the three models in this listing but still delivers substantial single-channel power from a compact chassis. 700W RMS × 1 @ 4Ω. 1300W RMS × 1 @ 2Ω. 2500W RMS × 1 @ 1Ω. 2800W burst output @ 1Ω. 10 Hz – 20 kHz frequency response. 1–4Ω stable operation. 0–12 dB bass boost centered at 50 Hz. Remote level control included. Power, protection, and clipping indicators. Dual smart cooling fans. 0 AWG power input capability. 200A recommended fuse. FRP-3.5K – 3500W RMS The FRP-3.5K steps output up to 3500 watts RMS at 1 ohm while maintaining the same narrow 5.5-inch chassis width that makes the FRP platform attractive for space-limited builds. 1000W RMS × 1 @ 4Ω. 2000W RMS × 1 @ 2Ω. 3500W RMS × 1 @ 1Ω. 4000W burst output @ 1Ω. Full-range single-channel Class-D architecture. Clip and protection monitoring. Remote level control. 300A recommended fuse. 10.2″ × 5.5″ × 2.36″ chassis. FRP-5K – 5000W RMS The FRP-5K is the highest-output model in this product group, delivering 5000 watts RMS at 1 ohm for systems with the electrical infrastructure and speaker configuration required to use that level of power safely. 1500W RMS × 1 @ 4Ω. 2900W RMS × 1 @ 2Ω. 5000W RMS × 1 @ 1Ω. 5600W burst output @ 1Ω. Full-range single-channel Class-D architecture. Clip and protection monitoring. Remote level control. 500A recommended fuse. 12.2″ × 5.5″ × 2.36″ chassis. Compact Design for Motorcycle and Powersports Builds High-output bagger systems often need multiple amplifiers, DSP hardware, distribution, battery upgrades, and substantial power wiring in very limited space. The FRP series keeps chassis width and height compact while increasing chassis length as output rises. FRP-2.5K 8.85″ × 5.5″ × 2.36″ for strong output where amplifier space is limited. FRP-3.5K 10.2″ × 5.5″ × 2.36″ with increased output while maintaining the same narrow width. FRP-5K 12.2″ × 5.5″ × 2.36″ for maximum output in this FRP product group. Protection and Thermal Management High-current amplifiers need proper thermal and electrical protection. DS18 equips the FRP platform with cooling and protection systems designed to help protect the amplifier and connected system during demanding operation. Smart cooling fan system. Thermal protection. Overload protection. Short-circuit output protection. DC output protection. High- and low-voltage protection. Power, protection, and clipping LED indication. Important: Protection circuitry is not a substitute for proper system design. Correct impedance, wiring, fusing, voltage stability, airflow, gain structure, and speaker protection remain essential. Built for Harsh Audio Environments DS18 uses protective treatment on the FRP amplifier circuit board to help resist moisture-related corrosion, while bonded internal components help improve vibration resistance. Those characteristics make the FRP platform well suited for motorcycles and powersports installations when the amplifier is mounted and protected correctly. Electrical System Requirements These are high-current amplifiers. The larger FRP models can require substantially more electrical capacity than a stock motorcycle charging system can continuously provide. FRP-2.5K recommended fuse: 200A. FRP-3.5K recommended fuse: 300A. FRP-5K recommended fuse: 500A. Use appropriately sized OFC power and ground cable. Install proper battery-side fuse protection. Keep grounds short and connected to appropriate low-resistance points. Evaluate battery reserve and charging-system capability before installation. High-output motorcycle builds may require upgraded battery capacity and electrical support. Electrical planning matters: Do not choose an amplifier based on wattage alone. A 2500W, 3500W, or 5000W amplifier must be supported by the motorcycle's complete electrical system. Available in Blue, Red or Titanium Each FRP power level in this listing is available in Blue, Red, or Titanium, allowing the amplifier finish to be matched to the rest of the build. FRP-2.5K – Blue / Red / Titanium. FRP-3.5K – Blue / Red / Titanium. FRP-5K – Blue / Red / Titanium. Installation and System Planning Calculate the final speaker impedance before selecting an amplifier model. Verify RMS speaker power handling against available amplifier power. Use correct crossover settings for the specific drivers being powered. Establish proper gain structure throughout the source, DSP, and amplifier chain. Use correctly sized power, ground, and speaker wiring. Fuse the main power cable appropriately at the battery. Provide adequate airflow around the amplifier. Monitor charging voltage under sustained load. Professional installation is strongly recommended for high-current motorcycle systems. Need Help Choosing Between 2500W, 3500W and 5000W? The correct amplifier depends on much more than the biggest wattage number. Speaker impedance, speaker count, RMS power handling, crossover range, electrical capacity, battery configuration, charging system, installation space, and the intended system goal all matter. Tell Garage Bagger Stereo what speakers you are running, how they are wired, what motorcycle you have, and what you want the system to accomplish. We can help determine which DS18 FRP model makes sense for the build. Start a Build Consultation Call 864-334-6131

Built for Harley Touring Bikes and Bagger Audio Builds

This collection is ideal for Harley Davidson touring motorcycles including Road Glide, Street Glide, and CVO models. Whether you’re powering fairing speakers only or adding saddlebag speakers for a full touring bike system, DS18 amplifiers deliver the output and headroom needed for louder, clearer performance in real-world riding conditions.

Fairing Speaker Amplification

Running upgraded fairing speakers without an amp leaves performance on the table. Adding amplification increases clarity, volume, and midbass impact, especially at highway speed where stock power gets overwhelmed.

Saddlebag Speaker Amplification

If your system includes saddlebag speakers, amplification becomes even more important. More speakers demand more power. A properly matched DS18 amplifier setup improves headroom, reduces distortion, and keeps your system balanced from front to rear.

Choose the Right Amplifier for Your Speaker Setup

The best DS18 motorcycle amplifier depends on your speaker count, channel needs, and target output level. A multi-channel amplifier is ideal for powering front and rear speakers, while higher-output setups deliver increased headroom for louder bagger audio builds.

  • Fairing speakers only: Choose a setup that delivers clean power and strong clarity at speed.
  • Fairing + saddlebag speakers: Use a higher output solution for full system volume and balance.
  • Maximum output builds: Prioritize headroom, stable performance, and correct installation parts.
