All-Weather 2-Channel Amplifier

The AudioControl ACX-300.2 is a two-channel car amplifier built for marine, UTV and motorcycle sound systems. It delivers 75 watts per channel at 4 ohms, 150 watts per channel at 2 ohms and 300 watts bridged at 4 ohms. An IPX6 rating protects the internals from heavy water exposure in open-air installations.

Installer-Friendly Wiring and Protection

Heavy-gauge quick-connect wiring allows fast, secure connections without special tools. The amplifier accepts both low-level preamp and high-level speaker inputs ranging from 500 mV to 12 Vrms. GTOTM Signal Sense automatically turns the unit on when an audio signal is detected, removing the need for a separate remote lead. A 30 A fuse rating is recommended for the power circuit.

Linkwitz-Riley Crossovers and Signal Quality

Built-in 12 dB/octave Linkwitz-Riley crossovers offer selectable 80 Hz and 120 Hz points plus a bypass option for full-range operation. Frequency response spans 26 Hz to 22 kHz with a signal-to-noise ratio of 102 dBA referenced to 50 W at 4 ohms. Total harmonic distortion plus noise remains below 0.05 percent for clean output.

Questions about this item

What input voltage does the ACX-300.2 accept in high-level mode?

High-level inputs accept 1 Vrms to 12 Vrms, letting you tap factory speaker outputs directly without a line-output converter.

What mounting clearance does the IPX6 chassis require?

The all-weather case is sealed to IPX6; leave enough space for the heavy-gauge quick-connect plugs and the 30 A fuse holder on the power lead.

How do I enable signal-sense turn-on on the ACX-300.2?

GTO Signal Sense activates automatically when it detects music on the speaker-level inputs — do not run a separate remote wire or the amp will stay on.
