AudioControl A800.1 Altitude Series mono subwoofer amplifier (800 watts RMS x 1 at 1.33 ohms)

Flying high in first class

AudioControl's Altitude A800.1 mono subwoofer amplifier's sleek anodized aluminum chassis protects the precision high-spec electronic components inside and provides high-temperature thermal dispersion through its stylish cooling fins. AudioControl designed this Altitude amplifier to power the subwoofer system in almost any vehicle — including some vehicles with stop-start electrical systems.

Performance

The A800.1 can power a single 4-ohm sub with 400 watts RMS, for those who want to add some bass-fill to their overall sound. For a 2-ohm sub setup, the amp'll put out 600 watts, so you'll hear and feel all the fine details of the bass clearly when you're on the go. Adjustable low-pass and subsonic crossovers plus a parametric-style bass boost help achieve perfect bass tone. In Spike Mode, the amp can handle three 4-ohm subs, wired together in parallel to equal a 1.33-ohm load, and send them a total of 800 watts, over 260 watts per sub. An optional wired remote bass knob lets you control the sub level from your front seat.

Volume-level security

The A800.1 has a Valet Mode feature that limits the amp's volume to 25% of its maximum when you engage it with your custom-installed switch (not included) — so parking lot attendants or your teenagers' friends can't damage your subwoofers by cranking up the volume too high when you're not around.
