ensure maximum output from your amplifier, use high quality,

ninimum and maximum gauge power and ground wire for your application.
The amplifier employs highly efficient circuitry, a custom-engineered
heat sink, and a unique Chassisink construction to maintain lower operating tem-
peratures. Additional cooling may be required if the amplifier is located in a tightly
confined area or when driving especially low impedance loads at extremely high
levels.

CIRCUIT BREAKERS AND FUSES
all audio components, the amplifier must be fused near the battery.
fuse or circuit breaker must be located within 18” of the batterv. This will
fire in the event of a cable. See the chart below to determine the correct
use value.
NTERNAL
Angina and A4 amplifiers are fused with automotive-type fuses.
n the event of blown power supply fuses, replace with the correct value fuse found

REMOTE TURN-ON
the “Remote” line to the turn-on lead from the source unit. When
is received, the amplifier will turn on. Note: Remote wire is not needed
vhen the Angina is using the speaker level inputs.
SIGNAL CABLE
Jse a high quality cable that will be easy to install and has minimal signal loss to
optimum performance.
SPEAKER CABLE
amplifiers will accept up to 8 gauge speaker cable. Use a high
flexible, multi-strand cable for best performance and longevity.

When mounting the amplifier, it should be securely mounted to either a panel in the
vehicle or an amp board or rack that is securely mounted to the vehicle. The
mounting location should be either in the passenger compartment or in the trunk of
the vehicle, away from moisture, stray or moving objects, and major electrical com-
ponents. To provide adequate ventilation, mount the amplifier so that there are at
least two inches of freely circulating air above and to the sides of it.

MOUNTING THE AMPLIFIER
Using the amplifier as a template, mark the holes on the mounting surface.
Remove the amplifier and drill the holes for the mounting screws.
Secure the amplifier to the mounting surface using the supplied hardware.
Run and connect the audio signal and remote turn-on cables to the ampli-
fier from the source unit.
Carefully run the positive cable from the amplifier to a fuse or circuit breaker
within 18” of the battery.
Connect the fuse or circuit breaker lead to the battery. Leave the circuit
breaker off or the fuse out until everything is bolted down.
Secure the ground cable to a solid chassis ground on the vehicle. It may be
necessary to sand paint down to raw metal for a good connection.
Double check each and every connection!
Reconnect the fuse or circuit breaker.
POWER UP
Power up the system and look at the Power LED; there may be a 2-3 second delay
from the time the source unit is turned on to the time that the LED on the amp turns
on, which is normal. Once the amplifier LED is on and the source unit is playing,
you should have sound coming from the speakers.
IMPORTANT ANGINA NOTE:
e initial power up connection will leave the amplifier power light on for abo
one minute after turning off. Normal operation will occur after that.
