INSTALLATION INFORMATION

Memphis Audio recommends the installation of our products to 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.

Tip 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 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 – this is often induced by the vehicles 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 above steps do not improve/reduce noise, the system should be checked by a professional audio installer at a Memphis Authorized Dealer.

SIGNAL INPUT CONNECTION

HIGH LEVEL INPUT WIRING

POWER INPUT WIRING

SPEAKER/SUBWOOFER WIRING

Speaker have a positive and negative marking on the terminals. These are used to indicate polarity and must be considered when wiring speakers or subwoofers to an amplifier. Amplifiers also have positive and negative markings on their speaker outputs. Use these marking to match polarities to ensure the speakers are in phase.
Failure to wire speakers or woofers in phase with one another will result in a loss of bass. The MXA600.6 require a minimum 2 impedance in stereo or 4 ohms in mono (bridged) mode.
Always check your speaker load with a multi-meter before hooking them up to the amplifier. Any Impedance (load) smaller than what is recommended will damage the amplifier! Such damage is not covered under warranty, so pay strict attention to what connections are made to the amplifier.
