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, in a bridged OR stereo conﬁguration

• 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 vehicle battery. Optimum performance depends on a normal battery supply voltage.

• For safety reasons, keep the volume of your vehicle audio system moderate while driving. This is so 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 the RCA input.

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.

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.
