VEHICLE ELECTRICAL SYSTEM
Amplifiers (regardless of brand name) will put on increased load on the vehicle's batt e ry and charging system. Cerwin Vega
Mobile recommends checking your alternator and battery condition to ensure that the electrical system hos 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 con be reduced
depending on your individual listening habits. To maximize the periormonce of your amplifier, we suggest the use of a reserve
power "Stiffening"copocitor (l Farad per l OOOW). In Cerwin-Vego Mobile products this is called a CVCAP2
WARNING:
Avoid running power wires near the low level input cables, antenna, power leads, sensitive equipment or harnesses. The
power wires carry substantial current and could radiate noise into the audio system through the audio cables.
l. Plan the wire routing as described in the "Importance of Pre-Planning" section. 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 coble
in place.
WARNING:
The B+ coble MUST be fused 18" or less from the
vehicle's positive battery post. Choose a location to
install a waterproof fuseholder under the hood and
ensure connections are water tight. If you do not use
the appropriate fuseholder, the connection will
eventually suffer corrosion from moisture and heat.
3. Trim the power coble within 18 inches (45.7mm)
of the positive battery post and splice in a in-line
fuse holder. DO NOT install the fuse at this time.
4. Strip l /2 inch (12.7mm) from the batt e ry end
of the power cable. Crimp and soldier a large ring
terminal to the cable. Connect the ring terminal to
the positive ( +) battery post.
