Rockford Fosgate 4-CHANNEL AMPLIFIER - Manual (Page 13)

MOUNTING AND LOCATION
The mounting location and position of the Punch 4-
Channel will have a great effect on its ability to dissipate
the heat generated in normal operation. The Punch 4-
Channel has a heatsink designed for heat dissipation
and internal shutoff circuitry to avoid overheating. It is
reasonably tolerant of mounting variations. However,
care should be taken to ensure adequate ventilation.
The temperature inside a trunk can reach as high as 175
°
F (80
°
C) during the summer months. Since the thermal
shutoff point for the Punch 4-Channel is 195
°
F (90
°
C),
it is easy to see that the amp must be mounted for
maximum cooling capability. Mounting the amplifier on
the floor or under the rear parcel tray prevents sufficient
convectional air flow cooling. Mounting the unit vertically
on a surface with the fin grooves running up and down
usually results in the best cooling.
Under the seat or floor mounting will work as long as there
is a minimum of 1” (2.5cm) of air gap above the amplifer's
heatsink.
Vertical mounting of the amplifier is still the best.

WIRING THE PUNCH
Caution! Be sure to avoid running the power wires
near the low level input cables, antenna, power leads,
sensitive equipment or harnesses. The power wires
carry substantial currents and could induce noise.
The following instructions explain how to prepare the
wires, connectors and fusing. We suggest you perform
these procedures prior to wiring and mounting your new
Punch 4-Channel amplifier.
1. Use approximately 18" (46cm) of the red power wire.
Strip one end of the wire back 1/2” (1.3cm) as shown
in the following diagram:
