RL880.4 - 880 Watts Full Range Class-D 4-channel Amplifier

The RL880.4 is a compact 4-channel amplifier built for real-world installs where space is limited but output isn't. At just under 5 inches long, it delivers up to 220W x 4 at 2 ohms or bridges down to 380W x 2 at 4 ohms — making it a flexible option for powering a full speaker stage or a mid-bass setup. The fully adjustable HPF and LPF crossovers (30–300 Hz) let you tune the signal without external processors.

• 4-channel output: 220W x 4 at 2 ohms, 140W x 4 at 4 ohms (14.4V)
• Bridgeable: 380W x 2 at 4 ohms for dedicated mid-bass or component applications
• Compact chassis: 3.97" x 4.92" x 2" fits tight mounting locations under seats or in trunk builds
• Adjustable crossovers: Independent HPF and LPF, both sweepable from 30 Hz to 300 Hz
• 4-way protection circuit: Thermal, voltage, and speaker DC protection built in
• Low distortion: THD+N under 0.3% at 1W with an SNR of 89.7 dB
• Clip indicator: Triggers at 1% THD to help set gain accurately
