Setup and Installation
Proper installation is crucial for optimal performance and longevity of your amplifier. It is recommended to have this unit installed by a professional if you are unfamiliar with car audio wiring.
- Mounting Location: Select a secure, dry, and well-ventilated location for the amplifier. The unit is designed for surface mounting. Ensure the location is protected from direct exposure to extreme heat or physical damage.
- Power Wiring: Connect the main power wire (typically red) from the amplifier to the positive terminal of your vehicle's battery. An inline fuse (not included) should be installed within 18 inches of the battery. The recommended amplifier kit is a 10-gauge kit.
- Ground Wiring: Connect the ground wire (typically black) from the amplifier to a clean, unpainted metal surface on the vehicle chassis. Ensure a solid electrical connection.
- Remote Turn-On: Connect the remote turn-on wire (typically blue) from the amplifier to the remote output of your head unit or an ignition-switched 12V source.
- Audio Input:
- Low-Level Input (RCA): If your head unit has RCA outputs, connect them to the amplifier's low-level inputs.
- High-Level Input (Speaker Level): If your head unit does not have RCA outputs, use the provided sealed wire harnesses to connect directly to your head unit's speaker outputs.
- Speaker Output: Connect your speakers to the amplifier's speaker output terminals using appropriate gauge speaker wire. Ensure correct polarity.
All wire harnesses are sealed to protect against environmental elements. Ensure all connections are secure and properly insulated.
Operating Instructions
Once the amplifier is correctly installed and all connections are verified, you can begin operation.
- Power On: Turn on your vehicle's ignition and head unit. The amplifier should power on automatically via the remote turn-on wire.
- Gain Adjustment: Carefully adjust the gain control on the amplifier. Start with the gain at its minimum setting and slowly increase it until the desired volume is achieved without distortion. Avoid setting the gain too high, as this can lead to distorted sound and potential damage to speakers.
- Bass Level Control: Use the bass level control to adjust the low-frequency output to your preference. This control allows for fine-tuning of bass response.
- Crossover Settings (if applicable): If your amplifier includes crossover settings, adjust them according to your speaker type and desired sound profile. Refer to your speaker's specifications for recommended crossover points.
Always ensure your audio source (head unit) volume is at a moderate level before making adjustments on the amplifier.
Maintenance
The Memphis Audio 16-MXA2.140 amplifier is designed for minimal maintenance due to its element-resistant construction. However, periodic checks can ensure continued optimal performance.
- Cleaning: Periodically wipe down the amplifier's exterior with a soft, damp cloth to remove dirt and debris. Avoid using harsh chemicals or abrasive cleaners.
- Connection Checks: Annually, inspect all wiring connections (power, ground, remote, input, output) to ensure they remain secure and free from corrosion.
- Environmental Protection: While element-resistant, avoid prolonged submersion or direct high-pressure water spray. Ensure waterproof control covers are properly seated.
