Mounting your amplifier
The mounting position of your amplifier will have a great effect on its
ability to dissipate the heat generated during normal operation. It has
an ample heat sink for heat dissipation, and is also designed with a
thermal shut-down circuit (for heat protection). Directing air flow over
the cooling fins will dramatically improve heat dissipation. Do not
enclose the amplifier in a small box or cover it so that air cannot flow
around the cooling fins.
Temperatures in car trunks have been measured as high as 175°F
(80°C) in the summer. Since the thermal shut-down point for the
amplifier is 185°F (85°C), it must be mounted in a location that allows
for maximum cooling capability. For maximum convective air flow in
an enclosed trunk, mount the amplifier in a vertical position or on a
vertical surface.
Cooling requirements are considerably relaxed when mounting inside
the passenger compartment, since the driver does not often allow
internal temperatures to reach the thermal shut-down point. Floor
mounting under the seat is usually sufficient, as long as there is at
least 1 inch (about 2 cm) above the amplifier’s cooling fins for
ventilation.
To mount the amplifier:
1 Select a suitable location that is convenient for mounting, is
accessible for wiring, and has adequate room for air circulation
and cooling.
2 Use the amplifier as a template to mark the mounting holes.
3 Drill the four mounting holes.
4 Secure the amplifier using the screws provided.
Connecting the power
We recommend 4 gauge (SL-2000D/2600D/3400D) wire (thicker if
planning for additional amplifiers) for both the power and the ground
wires. We recommend 12 gauge for the remote turn-on wire. Both
types are available at most mobile audio dealers or installation shops.
Caution
Use extreme caution while preparing to drill holes. Carefully
inspect underneath the surface before drilling.
Caution
Disconnect the vehicle’s battery before connecting to the
+12 Volts supply wiring.
