POWER SUPPLY CONNECTIONS
WARNING!
INSTALL THE FUSE AT THE BATTERY LAST!
Use conventional stranded copper wire for all connections. Finish the ends of the wires
at the amp and vehicle connection with the proper size terminals. Poorly made
connections, and /or inadequate wire size will generate excessive heat and may lead to
equipment failure.
The 12 VOLT + connection should be made directly at the positive battery post, using
the wire size recommended below, and fused within 18” of the battery. This fuse is vital,
and is primarily intended to protect the vehicle from damage in case of a dead short. The
fuse value at the battery should be at least the total fuse value of all of the amplifiers
being used.

The GROUND connection should be made directly to the chassis of the vehicle, as close
to the amp as possible. Make this connection with the same wire size as used for the 12
Volt + connection. Ensure that all dirt, grease, paint, and coatings are removed from
around the connection to the vehicle chassis. Use of a nut, bolt, and toothed type washer
is recommended for attaching the ground wire to the chassis.
The REMOTE TURN ON terminal should be connected to the source units’ remote turn
on lead or power antenna output wire. When using the power antenna wire, make certain
that this wire does not lose power when any source other than the radio is selected.
