RL680.1 - L-3 Compact Class Amplifiers

The RL680.1 is a compact mono amplifier built to push subwoofers hard without demanding much space. At just over 4" × 5", it delivers up to 680W RMS at 1 ohm — serious output from a seriously small footprint. Its variable subsonic and low-pass filters make it a purpose-built solution for bass-focused installations.

• 680W RMS at 1Ω — scales down to 500W at 2Ω and 260W at 4Ω for flexible wiring configurations
• Variable low-pass crossover from 50Hz–300Hz keeps only the right frequencies reaching your sub
• Subsonic filter (10Hz–35Hz) protects subwoofers from damaging infrasonic signals
• 0–12 dB bass boost with included bass remote for on-the-fly level control
• 4-way protection circuit — thermal, voltage, speaker DC, and clip indication at 1%
• 94 dB SNR and <0.23% THD+N deliver clean output at rated power
• Compact dimensions (4.13" × 4.92" × 2") suit tight installs under seats or in small enclosures
