Real Installs. Real Sound.
See what enthusiasts are saying — straight from their builds
Clean Power, Properly Delivered
Amplification That Holds Up Under Load
Stable Power Delivery
Built to hold its rated output under real load, so volume stays clean instead of falling away when the bass hits.
Protection Built In
Thermal, short-circuit and impedance protection shut the amp down safely rather than letting it fail.
Tuning Control
Onboard gain, crossover and bass controls let you match the amp to your speakers or subs instead of guessing.
Install-Ready
Standard terminals and mounting points make it straightforward to fit with the correct amp kit and fusing.
