Please consult with your local authorized dealer if you experience issues with your unit. You may also contact Memphis Audio customer service at 800-489-2300 or email tech support directly at: techsupport@memphiscaraudio.com. Do not attempt to return your amplifier directly to us without first calling for a return authorization number. Units received without an accompanying return authorization number will be processed more slowly. Additionally, you must include a copy of your purchase receipt from an authorized dealer for consideration of in-warranty service, otherwise, repair charges will apply. Units received without a receipt will be held for up to 30 days allowing us time to contact you and obtain a copy of the receipt. After 30 days, all units will be returned to you unrepaired.

POWER SUPPLY CONNECTIONS

Use conventional stranded copper wire for all connections. Finish the ends of the wire at the amp and vehicle with proper size terminals. Poorly made connections and/or inadequate wire size will generate excessive heat and may lead to equipment failure.

12 VOLT + CONNECTION
Make the 12V+ connection directly at the positive battery post using the proper size and fuse listed below. The fuse should be installed within 18″ of the battery. This fuse is vital to protecting the vehicle from damage in the case of a dead short. The fuse value at the battery should be at least equal to the total fuse value of all the amplifiers being used.

GROUND CONNECTION
Make ground connection directly to the chassis of the vehicle as close to the amp as possible. Make sure this connection is made with the same wire size as used for the 12-volt connection. Ensure that all dirt, grease, paint and coatings are removed prior to attaching the ground wire to the chassis.

REMOTE TURN ON
Remote turn on should be connected to the source unit’s remote turn on lead or antenna output wire. When using the antenna wire, make certain it does not lose power when any source other than the radio is selected.

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.
MX amplifiers were engineered to resist the elements. This does not mean this unit is fully waterproof. When choosing a mounting location, we recommend locating an area of your vehicle that remains dry and does not get submerged in water.

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 the 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 amplifier, the following should be tested first.

NO OUTPUT

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

ONLY ONE CHANNEL WORKS:

  • Confirm the speaker terminal strip connections are firmly connected
  • Check “balance” control on your signal source
  • If using RCA low-level inputs, reverse the input plugs at the amplifier. If the channel that is silent reverses position, the problem is in the source unit or connecting cable.

WEAK OUTPUT
Check input sensitivity control adjustment.

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.

RED LED IS ILLUMINATED

  • Speaker wire is shorted
  • Battery voltage too high
  • Battery voltage too low
  • Amplifier has overheated due to improper ventilation
