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 and enjoying your new amplifier.

GENERAL PRECAUTIONS

• This unit is designed for negative ground 12V DC operation only.
• Total system impedance must NOT be less than 2ohms, (DE300.2) stereo configuration
1 ohm for DE600.1D/DE1200.D
• 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 or moisture.
- It would be subject to 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 a normal 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)

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.
