Elevate your audio experience with AudioControl’s Altitude Amplifier Series, designed from the ground up to be sleek and modern with a minimalist aesthetic. The anodized matte grey aluminum chassis provides superior thermal dissipation. Performing at the top of their class, these amplifiers offer robust power and exceptional quality.

Altitude amplifiers feature Valet Mode, which safeguards your system from unintended damage by limiting the maximum volume to 25% when activated. They are also compatible with start-stop systems and electric vehicles, ensuring outstanding performance in any vehicle.

Pair Altitude amplifiers with AudioControl’s PNW speakers and Space or Spike subwoofers. This combination creates a
soundscape engineered to deliver the pure, uninterrupted power that AudioControl is known for.

Spike Mode allows you to connect three 4Ω subwoofers at 1.33Ω, unleashing even more power from your Altitude Series amplifier, designed to run cool at maximum output for extended periods of time.

With the ParaBASS control knobs you can fine-tune your bass for the ultimate audio experience. Customize your sound and feel the difference. Your bass, your way.

The power supply circuitry adopts advanced pulse width modulator integrated circuits that are designed to offer improved performance and efficiency.
Designed with Advanced HEXFET® Power MOSFETs from International Rectifier that utilize advanced processing techniques to achieve extremely low on-resistance and reliable fast switching speed.
Premium Toroidal Transformer for optimal electrical efficiency and minimal signal distortion.
