• Compact, stealth-friendly footprint: Slim dimensions (9.84" L x 4.53" W x 1.97" H) and light 3.7 lb weight fit behind panels or under seats without bulk.
• Auto Power On and control features: Auto power-on simplifies integration; features for precise tuning include bass boost, high pass and low pass filters, input gain, and X-Over control.
• Broad tuning controls: High Pass 120 Hz - 3 kHz; Low Pass 50 Hz - 250 Hz; Bass Boost 0 - 12 dB; Input Level Selector and Input Mode Selector for flexible input configurations.
• Sound and build quality specs: Frequency response 20 Hz - 20 kHz; S/N Ratio > 82 dB; THD < 1% / < 3%; Operating voltage 9 - 16 V DC; IPX5 rating; AGU fuse 80 A.

Benefits: This amplifier is designed for marine and power-sport audio builds where reliability, weatherproof connections, and space efficiency matter. Its 2-ohm stability and solid multi-channel output provide real-world headroom for four speakers, while the bridged option supports pairing channels for a higher-power sub or duo of speakers. The waterproof cabling, sealed control cover, and IPX5 rating protect the system in salt spray and rain, and the compact footprint makes stealth installations practical without sacrificing performance. Fine-tuned crossover controls, bass boost, and adjustable input levels give you precise tonal shaping to achieve clear, distortion-free sound at typical boat-volume levels. The combination of rugged construction, adaptable input options, and robust output makes it a capable centerpiece for a durable marine audio system.
