VEHICLE ELECTRICAL SYSTEM:
Amplifiers (regardless of brand name) will put an increased load on the vehicle's battery and charging
system. Diamond Audio recommends checking your alternator and battery condition to ensure that the
electrical system has enough capacity to handle the increased load of your stereo system. Original
equipment electrical systems, which are in good condition, should be able to handle the extra load of any
Diamond Audio amplifier without problems, although battery and alternator life can be reduced depending
on your individual listening habits.
WARNING:
Avoid running power wires near the low level input cables, antenna, sensitive equipment or harnesses.
The power wires carry substantial current and could radiate noise into the audio system through the
audio cables.
INSTALLATION:
1. Plan the wire routing. Keep RCA cables close together but isolated from the amplifier's power cables and
any high power auto accessories, especially electric motors. This is done to prevent coupling the noise from
radiated electrical fields into the audio signal. When feeding the wires through the firewall or any metal
barrier, protect them with plastic or rubber grommets to prevent short circuits. Leave the wires long at this
point to adjust for a precise fit at a later time.
2. Prepare the power wire for attachment to
the amplifier by stripping 5/8 inch (15.9mm)
of insulation from the end of the wire. Insert
the bare wire into the B+ terminal and
tighten the set screw to secure the cable
in place.
WARNING:
The B+ cable MUST be fused 18" or less from
the vehicle's positive battery post. Choose a
location to install a waterproof fuse holder
under the hood and ensure connections are
watertight. If you do not use the appropriate
fuse holder, the connection will eventually
suffer corrosion from moisture and heat.
3. Trim the power cable within 18 inches
(45.7mm) of the positive battery post and
splice in an in-line fuse holder. DO NOT
install the fuse at this time.
4. Strip 1/2 inch (12.7mm) from the battery end
of the power cable. Crimp and soldier a large
ring terminal to the cable. Connect the ring
terminal tothe positive (+) battery post.
