AudioControl A600.4 - Altitude Series 600W 4-Channel Amplifier, Class-D
AudioControl's Altitude Amplifier Series combines sleek, minimalist design with top-tier performance, featuring an anodized matte grey aluminum chassis for superior thermal dissipation. These amplifiers deliver robust power and exceptional sound quality, while Valet Mode protects your system by limiting the maximum volume to 25%. Compatible with start-stop systems and electric vehicles, they ensure reliable performance in any setting. Pairing the Altitude amplifiers with AudioControl's PNW speakers and Space or Spike subwoofers creates a powerful, high-quality soundscape that embodies AudioControl’s renowned audio excellence.
The power supply utilizes advanced pulse width modulator integrated circuits, enhancing both performance and efficiency. Equipped with cutting-edge HEXFET® Power MOSFETs from International Rectifier, these components ensure extremely low on-resistance and rapid, reliable switching speeds. A premium toroidal transformer maximizes electrical efficiency while minimizing signal distortion, complemented by low ESR capacitors that reduce power loss and internal heating. Precision metal potentiometers offer accurate tuning and durability, while 500V Class X2 capacitors with self-healing properties provide high-frequency surge protection and MOSFET safeguarding. Additionally, high-efficiency Ferrite Core Inductor filters reduce current eddy losses, supported by a class D intelligent driver IC with PWM modulation for powerful, efficient operation.

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.
