Alpine MRX-M110 Specification

The Alpine MRX-M110 is a high-performance monoblock car amplifier designed to deliver robust and clear audio output for subwoofers. It operates with a Class D digital amplifier circuit, enhancing efficiency and thermal management, making it suitable for compact installations. This amplifier provides a maximum power output of 1,900 watts at 2 ohms and 1,100 watts RMS at 2 ohms, ensuring powerful bass performance. It also offers 650 watts RMS at 4 ohms, accommodating various subwoofer configurations.

The MRX-M110 features a signal-to-noise ratio of over 85 dB, minimizing background noise and ensuring clean sound reproduction. Its frequency response ranges from 5 Hz to 400 Hz, allowing for accurate low-frequency audio reproduction. The amplifier includes a low-pass filter adjustable between 50 Hz and 400 Hz, and a subsonic filter set at 24 dB per octave at 15 Hz, which protects subwoofers from harmful frequencies.

Additional features include a variable bass boost of up to +12 dB at 50 Hz, providing users with the ability to customize the bass output according to their preferences. The amplifier is equipped with speaker-level inputs for easy integration with factory systems, as well as preamp RCA outputs for system expansion. It comes with a wired remote bass level control, allowing users to conveniently adjust the bass from the driver's seat.

The Alpine MRX-M110's compact design includes a rugged, cast-aluminum heat sink for effective heat dissipation, ensuring reliability and longevity. Its CEA-2006 compliance confirms its power ratings and performance standards, making it a reliable choice for car audio enthusiasts seeking powerful and clean bass amplification.

Alpine MRX-M110 F.A.Q.

How do I properly install the Alpine MRX-M110 amplifier in my vehicle?

To install the Alpine MRX-M110, first disconnect the vehicle's battery. Mount the amplifier on a stable surface with adequate ventilation. Connect the power, ground, and remote turn-on wires. Ensure the RCA inputs are connected to the head unit and connect the speaker wires to the output terminals. Finally, reconnect the battery and test the system.

What are the recommended settings for optimizing sound quality on the Alpine MRX-M110?

For optimal sound quality, set the gain control to match your head unit's output voltage. Adjust the crossover settings to suit your speaker and subwoofer specifications, typically around 80Hz for a low-pass filter. Fine-tune the bass boost and equalizer settings as per your preference and speaker capabilities.

Why does my Alpine MRX-M110 go into protection mode?

The MRX-M110 may enter protection mode due to overheating, a short circuit, or an impedance mismatch. Ensure the amplifier has proper ventilation, check the wiring for shorts or loose connections, and verify that the speaker impedance matches the amplifier's specifications.

How can I troubleshoot no sound output from the Alpine MRX-M110?

First, check if the amplifier is powered on and not in protection mode. Verify that all connections are secure, including power, ground, remote, and RCA cables. Check the speaker connections and inspect the fuse. If all connections are correct, try connecting another audio source to rule out a faulty input.

What are the maintenance tips for keeping the Alpine MRX-M110 in good condition?

Regularly clean the amplifier's surface to prevent dust buildup. Ensure all connections remain tight and corrosion-free. Periodically check the wiring for wear or damage, and verify that the amplifier remains well-ventilated to prevent overheating.

How do I connect the Alpine MRX-M110 to a factory head unit without RCA outputs?

Use a line output converter (LOC) to convert the factory head unit's speaker-level outputs to RCA level. Connect the LOC to the speaker wires and then run RCA cables from the LOC to the amplifier's input. Ensure the LOC is properly configured for a clean signal.

What is the maximum power output of the Alpine MRX-M110?

The Alpine MRX-M110 amplifier is rated at 1,100 watts RMS at 2 ohms, providing robust power for driving subwoofers. Ensure your subwoofer can handle this level of power to prevent damage.

How can I prevent overheating issues with the Alpine MRX-M110?

Install the amplifier in a location with sufficient airflow. Avoid placing it in enclosed spaces without ventilation. Keep it away from heat sources and ensure the fan and heat sinks are unobstructed. If overheating persists, consider adding external cooling fans.

What should I do if the Alpine MRX-M110 emits a humming sound?

Check for ground loop issues by ensuring the amplifier and head unit share the same ground point. Inspect the RCA cables for damage and ensure they are routed away from power cables. If necessary, use a ground loop isolator.

How do I adjust the gain setting on the Alpine MRX-M110?

Turn off all EQ and bass boost settings on the head unit. Play a test tone or music track at a moderate volume. Slowly increase the gain on the amplifier until you hear distortion, then back it off slightly until the sound is clean. This ensures optimal performance without overdriving the amp.
