OPERATION/INSTALLATION MANUAL
♦ When making connections, be sure that each connection is clean and
secure. Insulate final connections with electrical tape or shrink tubing.
Failure to do so may damage your equipment.
♦ A secure, clean ground connection is critical to the performance of your
Clarion car audio amplifier. Use the shortest ground wire possible to
minimize resistance and avoid noise problems.
♦ Refer to Figure 11 (below) when making electrical connections. Connect
the amplifier’s positive (+) power lead via a fuse directly to the positive
(+) terminal on the battery. Do not connect this wire to the car’s fuse
panel. Use the power cable calculator chart (see Figure 12 on page 17)
to determine the appropriate wire size for the amplifier’s positive (+)
power lead and the same-gauge black-insulated wire for the ground.
Caution: Clarion's Antenna/Amp output is restricted to 500 mA (MAXIMUM).
Do not replace the 0.5 A fuse with a higher value or you will damage
the unit, if more current is required when installing multiple amplifiers,
use this relay circuit.
