AUDIO SYSTEM AS Competition Amplifiers

INTRODUCTION

Thanks and congratulations for chossing this mobile audio for your amplification needs .The amplifiers have been significantly improved throughout years to assure quality and reliability. The latest technology has been incorporated into every product providing you with incredible power and unparalleled sound quality. Our simple, highly developed circuitry contributes to low distortion and the ultimate in efficiency. That’s why we are sure that your new amplifier will provide you with a sound value you can enjoy for years to come.

PRECAUTIONS

• Pay utmost attention if you install the amplifier into the driver’s compartment.
• Use Only in cars with a 12 Volt negative ground.
• Before wiring, disconnect the cable from the negative battery terminal to avoid short circuits or electrical shocks. Make the correct connections.
• Do not connect the positive and negative cable of the amplifier to the original cables of the car because of its low capacity.
• Do not damage pipe or wiring when drilling holes.
• Arrange the wiring so it is not crimped or pinched by a sharp metal edge
• Do not install the amplifier in locations which might hinder vehicle operations and do not install in locations with any moisture. Use the installation materials provided with the amplifier.
• Do not use bolts or nuts in the brake, airbags or other safety relevant systems to make ground connections.
• Warning! Amplifiers may produce sound pressure levels that exceed the threshold at which hearing loss may result. They may also impair a driver’s ability to hear traffic sounds or emergency vehicles. Practice safe listening when listening to your audio system.
• When the amplifier works in particularly hard conditions, it can research up to 90 °C . Make sure its temperature is safe before touching it. This amplifiers are developed for motor vehicle use only.

1. Power terminal
   GND: Connect the GND terminal/chassis ground.
   Please use 8AWG cable. Please refer to the wiring diagram for the length of the ground wire.
   REM: Remote boot control
   Connect the remote terminal to the remote output of your head unit. When using high level input, once the machine receives the signal, the power amplifier will automatically turn on (TURN ON). The remote connection of the power terminal (REM) will not be used.
   +12:
   It is recommended to use an 8AWG wire to connect here with the positive pole of the car battery.

2. Fuse Holder
   Two 30A fuses are installed on the power amplifier.

3. Speaker terminal
   Connect the(+) and(-) terminals to the speaker, making sure the polarity is correct. See the wiring diagram for specific connections.
