Dear customer, When properly installed and operated, your Bazooka MGA amplifier will give you years of clean uninterrupted sound reproduction. Therefore, we urge you to take a few minutes to carefully read through this manual. It will explain all of the features of your amplifier and help insure trouble free installation. Sound can be deceiving. Over time your hearing comfort level adapts to higher volumes of sound. What may have sounded normal can actually be too loud and harmful to your hearing.
SAFETY PRECAUTIONS ENGLISH Fuse amplifiers power wire at the battery. Be sure to fuse the power wire within 6” of the car's battery. This will protect the car's battery in case of a short circuit between the power amplifier and battery. THIS IS A MUST, the amplifier's built-in fuse will only protect the power amplifier not the car's battery! Use high grade wire connectors.
FEATURES AND BENEFITS Power Management and Cooling System To mantian cool operation, the fans will speed up and run at high speed when clipping is detected for 30 seconds or when the amplifier reaches high temperatures. If the amplifier reaches maximum temperature and goes into thermal protection, the fans will continue to run untill the amplfier cools down. Thermal trip Points 88C - Thermal Protection - Amplifier Shuts off to cool down.
ENGLISH Subsonic Filter A subsonic filter has been provided to filter out unwanted subsonic bass frequencies below the audible range of the subwoofer. This feature helps to improve the amplifier's overall performance since power is not wasted reproducing frequencies beyond the speakers' normal operating range. This feature works in conjunction with the Low-pass crossover to provide band-pass filtering. Phase Adjustment The phase switch allows for 0 or 180 degree phase adjustment for the woofers.
MOUNTING LOCATION Select the location in which you wish to mount the amplifier. Use caution when mounting amplifier, there are many wires, gas lines, vacuum lines, brake lines as well as a gas tank in the automobile. Make sure you know where they are when mounting the amplifier to avoid puncturing lines, shorting wires or drilling holes in the gas tank. Once you are ready, use a pencil to mark the mounting holes in the bottom panel.
ENGLISH CONNECTIONS Panels slide off to make connections easier. Be sure not to break plastic locking tabs! Rubber plugs can be removed to reveal channels for C.H.I.L water cooling kit! Removing these plugs makes panel removal easier.

Before making any connections, disconnect the car’s battery until the installation is completed to avoid possible damage to the electrical system. Connect the amplifier to the car's battery. Make your power connections using a 4 gauge power wire for your connections.

SPEAKER CONNECTIONS ENGLISH Make the speaker connections using speaker wire that is at least 12 gauge or heavier. As with any audio component, proper phasing of the amplifier and speakers is essential for strong bass response. When connecting, make sure that positive (+) from the amplifier is connected to the positive (+) of the speaker, and the same for negative (-).
MULTIPLE AMPLIFIER CONNECTIONS When running multiple amplifier’s in large systems all amplifiers can be linked together so the primary master amplifier can control all amplifiers. In the following example we show four amplifiers controlled by one master ampilifer. ENGLISH Master amplifier’s crossover, bass boost and subsonic adjustments control for the master and slave amplifiers. L R + MASTER AMPLIFIER SUBSON C FREQ Hz 1.) Set Phase to IN 2.
BRIDGED DUAL-AMP CONNECTIONS ENGLISH MGA’s Briged Dual-amp technology gives you the flexibility to combine the power of two of the same model amplifiers to double the output power into one speaker load. IMPORTANT! IN BRIDGED DUAL AMP OPERPATION, BOTH AMPLIFIERS MUST BE THE SAME MODEL OF EQUAL POWER. TWO MGA11000H’s OR TWO MGA11500H’s. Master amplifier’s crossover, bass boost and subsonic adjustments control both the master and slave amplifier. Source is set to the NORMAL position.
Connect (-) Speaker Terminals Together with 10 Guage Wire Minimum CHIL 1 MN FUSE 30A X 4 CHIL SLAVE AMPLIFIER + MASTER AMPLIFIER FUSE 30A X 4 *4 Ohm 2 Ohm Minimum CAUTION! In bridged operation, the amplifiers must see a 2 Ohm load or higher for the subwoofer(s). Any lower than the above mentioned impedance will cause the amplifiers to overheat and possibly cause permanent damage to the amplifiers.
ENGLISH REMOTE BASS CONTROL MODULE Before connecting the remote, it will be necessary to find a mounting location that will be easy to access for adjustment. Once you select your mounting location, you will need to run the control wire from the remote to the amplifier. To avoid possibility of induced noise from the car's electrical system (i.e. popping noises or engine noise), run the cable from the remote to the amplifier away from the car's electrical wiring.

ENGLISH TROUBLE SHOOTING THE SYSTEM We have put together this trouble-shooting guide if you experience problems after installing the amplifier. Please keep in mind that the majority of problems incurred are caused by improper installation and not the equipment itself. In addition, there are many components in the system that could cause various signal problems such as inducted electrical noise and engine noise.
