Installation - Diamond MICROV2 Series Owner's Manual

Installation

INSTALLATION -Pre Planning Section
WARNING: Prolonged exposure to sound pressure levels in excess of 100dB can cause permanent hearing loss.
DIAMOND AUDIO amplifiers can exceed that level so please exercise restraint when listening to your new amplifier.
GENERAL PRECAUTIONS
• This unit is designed for negative ground 12V DC operation only.
• Total system impedance must Not be less than 2 Ohms stereo, or 1 Ohm bridged for MICRO1V2. MICRO5V2 is
minimum 2 Ohms bridged on sub channel(ch5), and the MICRO4V2. MICRO5V2(ch 1, 2, 3, 4) is 4 ohms
bridged mono (stereo)
• Avoid installing the unit where: It would be subject to high temperatures, such as from direct sunlight or hot air
from the heater. - It would be exposed to rain, moisture, dust or dirt.
• Do not cover the unit with carpet or wires.
• Do not use the unit with a weak auto battery. Optimum performance depends on optimum battery supply
voltage.
• For safety reasons, keep the volume of your car audio system moderate while driving your vehicle so that you
can still hear normal traffic sounds outside your car.
• There is NO speaker level input connector, you can cut RCA's and solder the wires and connect directly thru low
level input(RCA) Or purchase the "optional " RCA Adaptor cable to make a cleaner connection, model - DAHILVL
MOUNTING PRECAUTIONS
Although DIAMOND AUDIO amplifiers incorporate heat sinks and protection circuits, mounting the amplifier in a
tight space without any air movement can still damage internal circuitry over time. Choose a location that provides
adequate ventilation around the amplifier. For easy system set-up, mount the amplifier so the side panel controls
will be accessible after installation. To increase thermal run times on low impedance loads, an additional fan is
recommended, remember any moving air across the amplifier will reduce heat. In addition, observe the following
precautions:
1. Using a felt pen mark the mounting hole locations.
2. Mounting the amplifier on carpet will significantly reduce air flow, resulting in reduced thermal run times.
3. Mount the amplifier on a solid surface. Avoid mounting to sub woofer enclosures or areas prone to vibration. Do
not install the amplifier on plastic or other combustible materials.
4. Prior to mounting the amplifier, make sure not to cut or drill into the fuel tank, fuel lines, brake lines (under
chassis) or electrical wiring.
WIRING PRECAUTIONS
1. Before installation, make sure the source unit power switch is in the OFF position.
2. Disconnect the negative (-) lead of the battery before making any power connections.
3. When making connections, be sure that each one is clean and secure. Insulate all of your connections. Failure to
do so may damage your equipment.
4. A secure clean ground connection is critical to the performance of your amplifier. Connect the ground directly to
the car chassis to minimize resistance and avoid any noise problems.
5. Add an external fuse on the amplifier's positive (+) power lead and connect it as close as possible to the
vehicle's (+) battery terminal. Use a rating that equals the total current consumption at full output of all
amplifiers in the system. This external fuse will protect the vehicle from short circuits that can cause a fire.
