Audio Control A800.1 ALTITUDE MONOBLOCK AMPLIFIER

The AudioControl A800.1 Altitude Monoblock Amplifier is a high‑power, single‑channel solution built for serious subwoofer duty in modern vehicles, delivering 800W RMS at 1.33Ω with a thermally optimized anodized aluminum chassis. Its Start‑Stop and EV compatibility, plus advanced protection and tuning features, keep performance reliable in today’s cars.

• Power Output (RMS) at 14.4V: 400W x 1 @ 4Ω; 600W x 1 @ 2Ω; 800W x 1 @ 1.33Ω. Real‑world impact: supports demanding subwoofers and enables high‑headroom performance in a single‑channel configuration, including bass systems that run at lower impedance for maximum output.
• Spike Mode: enables three 4Ω subwoofers at 1.33Ω. Real‑world impact: increases total bass capacity and allows a multi‑sub setup without multiple amplifiers while staying within the Altitude series’ cooling design.
• ParaBASS Low Frequency Contouring: dedicated bass tuning controls. Real‑world impact: lets you sculpt the bass to taste and room/speaker response for a more musical, controlled low end.
• Valet Mode: limits maximum volume to 25% when activated. Real‑world impact: protects your system from unintended damage in shared vehicles or parking situations.
• EV Start‑Stop Compatible: compliant up to 17V. Real‑world impact: reliable operation in modern vehicles with start‑stop technology or electrified systems.
• Inputs & Crossover Features: Preamp 2 inputs; Line-Level inputs up to 6 V max; Speaker-Level inputs up to 20 V max; GTO Signal Sense; Linkwitz‑Riley crossovers; Subsonic filter (Variable); Low Pass freq range 60 Hz–120 Hz. Real‑world impact: flexible integration with head units, multiple signal sources, and precise control over the audible bandwidth for a clean, room‑friendly install.
• Build Quality & Components: anodized matte grey aluminum chassis; Premium toroidal transformer; HEXFET Power MOSFETs; low ESR capacitors; 500V X2 capacitors; high‑efficiency ferrite core inductors; PWM modulator with protection. Real‑world impact: sustained high power with efficient operation and reliability under demanding duty cycles.
• Physical Specs: 10.9" W × 6.7" D × 2.1" H; 6.05 lb. Real‑world impact: compact footprint fits a wide range of vehicle installations while delivering substantial power.

In a complete system, the A800.1 is well suited to drive a dedicated subwoofer ensemble or a Spike‑Mode capable multi‑sub configuration, and it pairs well with AudioControl’s PNW speakers and Space or Spike subwoofers to deliver authoritative, uninterrupted power. The combination of ParaBASS tuning, precise crossovers, and efficient, cool operation supports high‑fidelity bass with minimal distortion, even in long, demanding listening sessions.
