Momentum MMA 300 - Manual (Page 3)

Thank you for purchasing this Momentum Amplifier.
Please read this manual carefully before beginning your installation. Should you need technical assistance during or after your installation,
please call our technical hot-line at 732 370 5400 between 10:00 AM and 5:00PM EST.
WARNING: Use of this amplifier at extreme high volumes for extended periods of time may cause hearing loss and or hearing damage.
During periods of prolonged high volume levels it is recommended that you use ear safety devices. Playing Momentum amplifiers at high
volume levels while driving will impair your ability to hear necessary traffic sounds. While driving always keep your sound volume at
reasonable volume levels.
When installing the amplifier secure it tightly. An amplifier not mounted or not mounted tightly can cause serious injury to passengers and
your vehicle if set in motion by an abrupt driving maneuver or short stop.

INSTALLATION DIRECTIONS
The power connections can accept 8 to 10 gauge wire. Be sure to strip just enough wire that fits into the terminal without exposing excess
copper. This will protect against shorts from exposed wires which may touch.
Momentum amplifiers feature very sophisticated protection circuits. Should the amplifier reach an unstable operating temperature
greater than 80 degrees C it will shut down. Allow the amp to cool sufficiently before restarting the system. In some instances the Logic
control of the power supply will not shut down the amplifier completely but will spurt the amp on and off. Turn off your system and allow it to
cool before restarting again. If you live in a hot climate, you may want to consider installing a cooling fan in your system.
Should the amplifier encounter a speaker short circuit, it will go into the Diagnostic mode and shut down. The Diagnostic LED will light on the
side panel. Turn off your system and disconnect all the speakers from the amplifier. Turn the system on, make sure the diagnostic LED is not
on and begin wiring your speakers back to the amp one at a time. The speaker which causes the amp to go back into Diagnostic is the
speaker with the short. Disconnect this speaker again before restarting the system.
Other protection circuits include Input Overload, Reverse Polarity and DC Offset protection.
POWER/GROUND/REMOTE WIRING
Connect the amplifier 12V+ connection directly to your car battery using at least 10 gauge primary wire. You should install a secondary in-
line fuse in the primary wire near the battery connection.
Connect a second wire of equal gauge to the ground connection of the amp and secure it to a welded chassis member of the car.
Connect a third wire to the Remote connection of the amp directly to the head unit amp turn-on wire or radio power antenna lead. This will
control that the amplifier turns on when the radio is on.
