INSTALLATION INFORMATION

Memphis Audio recommends the installation of our products be performed by an Authorized dealer. Attempting an installation project on your own or through an unauthorized source may result in damage to your products and may potentially void your warranty.
MXA amplifiers can be mounted in numerous locations, we typically recommend mounting them away from the elements. We recommend mounting them in an area that avoids direct contact with water. A proper mounting location will also allow for adequate ventilation allowing heat to dissipate.

WARNING
For your safety, always inspect the mounting location carefully to ensure you are not drilling into any electrical, hydraulic, fuel, or fluid lines. Always check your speaker load with a multi-meter before connecting the amplifier. Connecting any speaker load lower than the rated impedance of the amplifier will result in damage to the amplifier. Damage of this nature is NOT covered under warranty. Please pay close attention to what connections are made to the amplifier.
If you are uncertain or uncomfortable proceeding with your installation, please contact your local Authorized Memphis Audio Dealer

TROUBLESHOOTING

When troubleshooting your amp, speaker and speaker wires should be tested first
NO OUTPUT

• Confirm all wiring is firmly connected.
  Both +12V and REM terminals must have +12 Volts present and GND must be connected to the chassis ground or to the negative battery terminal.

• Confirm the signal source is connected and supplying an output signal. To confirm the amp is working, connect an RCA patch cord to the line inputs of the amplifier (do not connect the other end of the patch cord). Briefly tap the center pin of each disconnected RCA with your finger. This should produce a noise (brief static or hum) in the speakers.

• If the amp is hot, check the speaker impedance or load. The total minimum impedance of all speakers should not be lower than the rating of the amp

WEAK OUTPUT

• Check gain control adjustment
• Check speaker impedance.

UNWANTED NOISE

• Whine that increases and decreases with engine speed – confirm the Amp & Source unit are grounded properly.
• Clicking or popping noise at a rate that follows engine speed – is often induced by the vehicle’s ignition system. Confirm that the vehicle is equipped with resistor spark plugs and wires. The ignition system may need service.
• Noise can be caused by routing speaker input wires too close to the light wires and other accessory wires in the vehicle. Re-route wires to avoid unwanted interference.
• If the above steps do not improve/reduce noise, the system should be checked by a professional audio installer at a Memphis Authorized Dealer.
