If your MB QUART Car Amplifier system doesn't turn on, begin by checking all fuses and connections. Also, measure the +12 volt and remote turn on voltages at the amplifier terminals.
Why is my MB QUART FORMULA FX1.400 overheating?
Your MB QUART Car Amplifier might be overheating due to inadequate cooling. Relocate or remount it to allow better airflow. Another cause may be driving high power levels into low impedances. Try reducing the volume or ensuring the loudspeaker impedance meets the recommended specifications.
What causes low output power in my MB QUART Car Amplifier?
Low output power in your MB QUART Car Amplifier can be caused by improperly set level controls. Ensure they are correctly configured. Also, check that the battery voltage at the amplifier’s terminals is at least 11 volts. Inspect all +12 volt and ground connections as well.
Why does my MB QUART Car Amplifier keep blowing fuses?
Your MB QUART Car Amplifier might be blowing fuses due to using loudspeaker impedances below the recommended minimums. Also, a short on the main +12 volt cable from the battery to the vehicle chassis will cause the main fuse to blow.
What to do if MB QUART FORMULA FX1.400 goes into diagnostic mode?
If your MB QUART Car Amplifier goes into diagnostic mode, try these steps: 1. Disconnect all RCA and speaker leads, leaving the +12 volt, power ground, and remote leads connected. 2. Turn the amplifier back on. If the diagnostic LED lights up, it indicates an internal fault. 3. Plug the RCA cables back in and reset the amplifier to check for input faults. 4. Connect the speakers one at a time to identify any faulty speakers or wiring.
How to eliminate a ticking or whine that changes with engine RPM in my MB QUART FORMULA FX1.400?
To eliminate a ticking or whine that changes with engine RPM in your MB QUART Car Amplifier: * Relocate RCA cables that may be too close to a fuel pump or distributor. * Check that the head unit ground is connected directly to the vehicle chassis, not using factory wiring. * Try supplying the head unit with a clean +12 volt supply directly from the battery +, instead of using a supply from the in dash wiring/fusebox.
How to get rid of hiss or white noise from MB QUART Car Amplifier?
To reduce hiss or white noise from your MB QUART Car Amplifier, readjust the amplifier level controls, following the setup procedures. If the issue persists, unplug the amplifier input RCA cables; if the hiss reduces, the source unit is likely the cause.
How do I fix a constant whine in my MB QUART FORMULA FX1.400 system?
To fix a constant whine in your MB QUART Car Amplifier system, check all connections, paying special attention to ensure good grounds. Also, make sure that no speaker leads are shorting to exposed metal on the vehicle chassis.
