VEHICLE ELECTRICAL SYSTEM

Amplifiers (regardless of brand name) will put on increased load on the vehicles battery and charging system. Cerwin
Vega Mobile 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 CVM amplifier without problems, although battery and alternator
life can be reduced depending on your individual listening habits. To minimize the performance of your amplifiers, we
suggest the use of additional batteries. Remember that it takes power to make power. Energy isnt FREE.
SPECIAL NOTE: YOU WILL NEED 1/0 GUAGE WIRE ...OFC...NOT CCA WIRE!!!
WARNING:
Avoid running power wires near the low level input cables, antenna, power leads, sensitive equipment or harnesses. The
power wires carry substantial currant and could radiate noise into the audio system through the audio cables.
1. Plan the wire routing as described in the "Importance of Pre-Planning" section. Keep RCA cables close together but
isolated fiom 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 (1 5.9mm) 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
Vehicles positive battery post. Choose a location to
install waterproof fuse-holder under the hood and
ensure connections are water tight. 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 an inline 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 to the positive (+) battery post.
SPECIAL NOTE: THESE AMPLIFIERS CAN
DRAW MASSIVE AMOUNTS OF CURRENT
BE AWARE!!!!
