An additional temperature monitoring circuit protects the D7 amplifier

under extreme high power or extreme high-ambient temperature conditions.

As the heat sink temperature reaches 185 degrees Fahrenheit, this circuit will

shut down the high-current rail voltages, tuning the amplifier off while it cools

down. The fan will remain on to ensure proper cooling of the amplifier. When

the amplifier cools down to a safe operating temperature, the amplifier will turn

itself back on and play normally.

If a problem arises, refer to the troubleshooting section (page 15) or call the

Diamond Audio Technical Department at (480) 813-6205 for assistance.

WORD ABOUT BATTERIES

AND HIGH OUTPUT ALTERNATORS...

The battery in your car is a chemical storage device for electrical energy

generated by the alternator. It is capable of briefly supplying high currents for

cold starting the vehicle as well as powering other important electrical loads

either partially or entirely for a limited period when the engine is off.

In order to supply the power required for ignition, lighting, large audio

systems etc. a car needs its own efficient, reliable, and constantly available

source of energy. When the engine is stopped, the battery is the vehicle's

energy source. When the engine is running, the alternator is the on-board

"electricity generating plant." It is the job of the alternator to supply power to

all current-consuming loads (including the audio system).

Alternator output, battery capacity, and power demand of all electrical loads

and systems must be matched as ideally as possible so the entire system is

reliable and trouble-free in operation.

In the most basic of terms, this means that car audio is gasoline powered.

Extra batteries are primarily for the extended operation of your audio system

when the engine is off or for SPL competitions where high sound pressure

levels are generated for short periods of time and large battery racks are

needed to provide the necessary current demanded by the many amps used.

D7 Professional Reference Series Amplifiers are capable of reproducing "concert

level" volumes with incredible accuracy. Care must be taken to ensure that your

vehicle is capable of supplying the voltage and current required by such a

system.

POWER CABLE G AUGE CHART

Note: If you are installing multiple amplifiers, add up the total current draw for

all of them and choose the appropriate gauge based on the grand total.

Example:

Amplifier 1: D7054 (driven at 4 ohms stereo) =

Amplifier 2: D7401 (driven at 2 ohms mono) = 132 amps

Grand Total = 165 amps

33 amps
