INTRODUCTION

This manual provides information on the features, instal­lation, and operation of the Punch 2-channel Amplifiers.
We suggest you save this manual for future reference.

We strongly recommend you have your Authorized Rock­ford Fosgate Dealer and Service Center install the new
Punch amplifier. If you do choose to install the amplifier
yourself, please be sure to read the entire manual before
beginning.

Notes on
Internal
Circuitry

The Rockford Punch 40DSM, 60DSM, 100DSM and
200DSM automotive stereo power amplifiers provide
state-of-the-art sound in cars, vans, boats, or wherever a
high current 12 volt power source is available.

“Discrete Surface Mount” (DSM) technology is utilized in
the crafting of all our Punch amplifiers. This process
provides greater ruggedness and consistency of both
components and layout. Already used heavily in aero­space, industrial and automotive applications, this tech­nology is also highly advantageous in the hostile automo­tive environment.

The Punch adjustable input circuits are designed to
match almost any music source. The amplifiers will drive
most normal speaker types.

Internal circuitry in the Punch amplifier prevents damage
due to speaker terminal shorts. The Punch incorporates
internal battery line filtering and extensive noise preven­tion circuitry.

The Punch Equalization circuit is best utilized and de­signed to compensate for the acoustic inadequacies of
the automotive environment. This patented circuitry will
correct for the poor bass response and natural high
frequency roll-off inherent in the world of automotive
stereo. The result is full-range sound without the unpleas­ant changes in the mid-range sound produced by most
tone control and equalizer circuits.

High powered audio amplifiers must always address the
problem of power device reliability. In particular, load fault
conditions can easily destroy an amplifier that is not
carefully designed. Rockford Fosgate has answered this
problem with the development of Real Time Power Pro­tection (RTPP).

The RTPP circuits protect the Punch amplifiers by multi­plying output device voltage and current values to obtain
approximate instantaneous device power. This instanta­neous power calculation is then processed through a time
constant closely modeling the device heating time. If the
resulting modeled junction temperature exceeds a set
threshold, gate drive to the output devices is limited.

To get a better understanding of the Punch let’s take a
closer look.

CONTROLS AND FEA TURES

This section describes the various controls and features of
the Punch amplifiers.

Housing

End Caps

Mounting
Screws

The cast aluminum heatsink of the Punch is designed for
high performance cooling. The raised design of the hous­ing allows cables and wires to run underneath the unit.
This provides for greater wiring flexibility and protects the
cables from damage caused by excessive heat and bend­ing.

Interchangeable end caps conceal the wiring and input
cables, giving the amplifier a clean, "stealth" look. Also
incorporated, is a holding dimple built into the end cap.
This small feature enables the cap to be held in place while
being mounted.

The end caps are secured to the housing with flush
mounting, captive screws.

Four (4) custom, round, hex screws included in the acces­sory pack hold the unit in place. These screws are covered
when the end caps are installed.

Connector

The Punch is turned on by connecting the blue remote
turn-on wire to the source unit’s “Accessory” or “Auto
Antenna” lead, either of which will go to +12 volts when the
source unit is turned on.

The LED illuminates red when the unit is turned on.

These connectors are used to supply power and ground
to the amplifier and accept 12 AWG - 8 AWG wires.*

interconnecting cable and other products to complete your
installation. Ask your Authorized Rockford Fosgate Dealer
