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.  In which large battery racks are needed
to provide the necessary current demanded by the many amps used.

D5 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.

5   Diamond Audio Technology

POWER (+12V)

Strip approximately 1/2 inch of insulation from the end of the power cable
going to the amplifier. Insert the stripped cable into the power block on the
end of the amplifier and tighten the Allen screw.  Repeat for each amplifier
installed.

GROUND

For low power systems, locate a fairly thick metal area near the amplifier(s).
Inspect around and under the chosen area to make sure you won’t drill into
wires, brake or fuel lines, computers, etc. Remove any paint and carpet glue to
a spot approximately 1 inch in diameter. Drill a hole into the middle of this
area. Cut a length of ground cable long enough to go from the ground point
to the amplifier. Terminate the ground cable with a ring connector and attach
it to the bare metal using a bolt, star washer and nut. Seal the area from above
and below to prevent rust. Strip approximately  1/2 inch of insulation from the
other end of the cable and insert it into the ground block on the amplifier and
tighten the Allen screw.  For multiple amplifier systems, a ground distribution
block is recommended.  Cut a length of cable long enough to go from the
ground distribution block to the amplifier. Strip approximately 1/2 inch of
insulation from each end of the ground cable.  Insert one end into the ground
distribution block and tighten the Allen screw. Insert the other end of the
cable into the ground block on the amplifier and tighten the screw. Repeat for
each amplifier installed. Run a cable (the same gauge as the main power cable)
from the ground distribution block to the negative terminal of the system
battery.

Your 

D5 Professional Reference Series Amplifier

is designed to accept up to 4

gauge power and ground cable.
