The Altitude Series is built with a minimalist aesthetic and effective heat dissipation, allowing the A800.1 to run cool at maximum output for extended periods.
Features
- High/low input modes
- GTO Signal Sense
- Linkwitz-Riley crossovers
- Start-stop compliant
- ParaBASS low frequency contouring
- Valet Mode option
- Optional remote level control (ACR-1)
- EV compliant up to 17V
- Spike Mode enabled
Valet Mode limits maximum volume to 25% when activated, protecting your system from unintended damage. The A800.1 is also compatible with start-stop systems and electric vehicles up to 17V.
Spike Mode lets you connect three 4 ohm subwoofers at 1.33 ohms, unlocking the full 800 W RMS from the amplifier. ParaBASS control knobs allow precise low-frequency tuning to suit your preference.
If your vehicle uses a factory head unit, AudioControl's LC2i 2 Channel Line Out Converter or LC7i 6 Channel Line Out Converter can be used to feed a clean RCA signal into the A800.1.

About the AudioControl A800.1
From our tech experts at CEN
The AudioControl Altitude A800.1 is a monoblock subwoofer amplifier delivering 800W RMS at 1.33 ohms (400W at 4 ohms, 600W at 2 ohms). Part of AudioControl's Altitude Series, it includes a Linkwitz-Riley low-pass crossover (60–120 Hz), ParaBASS bass contouring, a variable subsonic filter, and is start-stop and EV compliant up to 17V.
Who it suits
The A800.1 suits anyone upgrading to a dedicated subwoofer amplifier in a car or EV. Spike Mode allows three 4-ohm subwoofers to run at 1.33 ohms, making it well suited to multi-sub builds. For more power, the AudioControl Altitude A1500.1 offers 1500W.
Our tech experts advise
The A800.1 measures 10.9" wide, 6.7" deep and 2.1" high, so check your boot or under-seat space before buying. It accepts both high and low-level inputs, so a factory or aftermarket head unit will work. If your car has no RCA outputs, you will need a line output converter before connecting. Installation is priced per vehicle; see our car audio installation page for details.
