• (1) Massive Audio H12004 4-Channel Hippo Series Amplifier

The Hippo Series High-Performance Amplifiers are the perfect match for Hippo Series Subwoofers, engineered to deliver extreme power, superior efficiency, and audiophile-quality sound. Built with Massive Audio’s exclusive "Massive Core" design, these compact yet powerful amplifiers add tremendous headroom for clean, undistorted playback even at peak levels.

The Massive Core power supply with oversized toroids and transformers ensures stable current flow, driving even the most demanding subwoofers and speakers with ease. With four-layer PCBs, surface-mount components, and computer-assembled circuitry, the H12004 guarantees long-term reliability and consistency while minimizing unwanted noise and distortion.

A hybrid cooling system combines convection and fan-assisted cooling, ensuring stable performance under extreme loads. Advanced Reactive Load Monitoring (RLM) and 7-Way Sentinel Protection Circuitry safeguard your investment by constantly monitoring heat, voltage, and current — engaging only when needed to protect your amp and speakers without disrupting performance.

Engineered in the USA with the highest quality parts, the Hippo Series H12004 is conservatively rated, CTA-2006 compliant, and designed to provide maximum power output, low noise, and long-lasting reliability in any car audio system.
