TROUBLESHOOTING

No Output:

• Confirm all wiring is firmly connected.
  Both +12V 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 via Bluetooth or the auxiliary cable is connected to both the source and the MXA46SB28 Weak Output
• Check Bluetooth device volume level.

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.

Red LED is Illuminated

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

If above steps do not improve/reduce noise, the system should be checked by a professional audio installer at a Memphis Authorized Dealer.
