Frequently Asked Questions - ACX-300.2 AudioControl
How do I connect the ACX-300.2 to my car stereo?
Connect the RCA outputs from your stereo to the amplifier's RCA inputs. Ensure the head unit's remote turn-on wire connects to the amplifier's REM terminal. Use appropriate gauge power and ground wires connected to battery and chassis.
What size power wire should I use?
For a 600W max amplifier, use 4 AWG power and ground wire for optimal performance. Refer to the manual for specific current draw.
How do I set the crossover frequencies?
Use the LPF (low-pass) for subwoofers and HPF (high-pass) for mid/high speakers. Adjust the crossover knob to the desired frequency, typically around 80 Hz for subwoofers.
What is the purpose of the bass boost?
The bass boost (0-18 dB @ 45 Hz) increases low-frequency output. Use sparingly to avoid distortion or speaker damage.
Can I bridge the amplifier for more power?
Yes, the ACX-300.2 can be bridged to a single channel, delivering up to 600W RMS to a 4-ohm load. Connect the positive terminal of channel A and negative of channel B to the speaker.
What is the input sensitivity range?
The input sensitivity is adjustable from 200 mV to 8V, allowing compatibility with various head unit output voltages.
How do I minimize noise (hiss or alternator whine)?
Keep signal wires away from power cables. Use high-quality RCA cables and ensure a good ground connection. Add a ground loop isolator if needed.
What speakers can I use with this amplifier?
The amplifier works with 4-ohm speakers (or 2-ohm when not bridged). Pair with speakers rated at least 150W RMS per channel for best results.
How do I protect the amplifier from overheating?
Ensure proper ventilation; mount in a location with airflow. The amplifier has thermal protection that shuts it down if overheating.
What is the warranty period?
AudioControl typically offers a 5-year warranty from the date of purchase. Register your product online to activate.
