AudioControl A800.1 Altitude Subwoofer Amplifier

Take your car audio to new heights with the AudioControl A800.1 Altitude Mono Amplifier, part of the sleek and modern Altitude Series. Built with an anodized matte grey aluminum chassis, it ensures superior thermal dissipation while delivering top-tier power and sound quality. Designed for performance, this amplifier provides robust, high-efficiency output for an immersive listening experience.

Equipped with Valet Mode, the Altitude amplifier protects your system by capping the volume at 25% when activated, preventing accidental damage. It’s also compatible with start-stop systems and electric vehicles, ensuring reliable operation in any setup.

For the ultimate sound experience, pair the Altitude Series amplifiers with AudioControl’s PNW speakers and Space or Spike subwoofers—a combination engineered to deliver pure, uninterrupted power. Spike Mode allows you to connect three 4Ω subwoofers at 1.33Ω, maximizing output while keeping the amplifier cool even during extended high-performance use.

Fine-tune your bass with ParaBASS control knobs, allowing precise customization for deep, punchy low-end response. Your bass, your way.

Under the hood, the A800.1 is built for efficiency and durability:

Advanced PWM circuitry ensures improved performance and efficiency.
HEXFET® Power MOSFETs provide ultra-low resistance and fast, reliable switching speeds.
Premium toroidal transformer minimizes signal distortion for clean power delivery.
Low ESR capacitors reduce power loss and internal heat buildup.
Precision metal potentiometers allow accurate tuning with durable construction.
500V Class X2 capacitors with self-healing properties offer high-frequency, high-current protection.
High-efficiency ferrite core inductors optimize power output with minimal energy loss.
Class D intelligent driver IC with PWM modulation and HEXFET protection delivers outstanding power and efficiency.
