I N T R O D U C T I O N
Rockford engineers designed the Punch 2-channel amplifiers to
withstand the rugged automotive environment while delivering
superior sound quality in a flexible, reliable, and efficient pack-
age. A grounding technique called TOPAZ was used to eliminate
noise problems associated with car audio systems, while flexibil-
ity was accomplished with the use of a built-in XCard. Reliability
was accomplished with the use of protection circuits called RTP
and NOMAD, while MOSFET and DSM technology improve
amplifier efficiency. The result of these components give the
Punch amplifier awesome sound quality in a “Bullet Proof”
package. An explanation of these technologies, some exclusively
designed by Rockford, are described in the Technical Design
Features.

RO C KFO RD FO SG AT E AC C ESSO RI ES
The following accessories were designed to enhance the perfor-
mance of the Punch 2-channel amplifiers.
Energy Storage Capacitor
The Punch capacitors are used to provide extra current needed by
amplifiers to reproduce musical transients. The Punch Caps also
have the natural ability to filter AC ripple caused by the alternator,
reducing the chance of noise in the system. The Punch Caps will
maximize both the sound quality and performance that Rockford
Fosgate amplifiers can deliver.
Punch Link (FG-LINK)
The Punch Link is a specially cast heatsink interconnect which
allows you to join any of our current Punch or Punch Power
amplifiers together. While providing additional cooling through
the coupling process, the Punch Link adds the finishing touch by
giving you the look of one awesome amplifier.

TECH NICAL DESIGN FEATURES
N TOPAZ (Tracking Operation Pre-Amplifier Zone)
The TOPAZ (Tracking Operation Pre-Amplifier Zone) circuitry
solves ground loop noise problems common to automotive
amplifier design. This innovative new development allows vastly
improved isolation of the input signal grounds from the power
supply ground of the amplifier. This is accomplished by allowing
the source unit to control the potential “environment” of the
entire input structure or “zone” of the amplifier. This process
improves the noise rejection of the amplifier by 30-40dB – an
astounding 30-100 times better than amplifiers without TOPAZ.
THE RESULT: Elimination of troublesome ground loop noise
between source and amplifier.
N RTP (Real Time Protection)
NOMAD (NOn-Multiplying Advanced
Decision)
The Punch and Power amplifiers use an analog computer
process to maximize safe output power under all operating
conditions. Rockford Fosgate pioneered and developed RTP
(Real Time Protection), a crucial element in the performance
edge of our amplifiers. The innovative NOMAD (NOn-Multiply-
ing Advanced Decision) system is the most sophisticated version
of this technique ever used, bringing previously unavailable
levels of accuracy, stability, temperature immunity and reliabil-
ity to this critical process. NOMAD makes advanced decisions
based on device voltagesto preciselycontrolthe awesome levels
of current available in the output MOSFETs to safe values – but
only when absolutely needed.
THE RESULT: Extremely fast protection system that always
protects the amplifier and never degrades the sound.

N DSM (Discrete Surface Mount) Technology
The DSM (Discrete Surface Mount) manufacturing process com-
bines the advantages of both discrete components and integrated
circuitry. Rockford Fosgate is the only American amplifier manu-
facturer to have invested millions into this process. DSM compo-
nents differ from conventional discrete components in three
different ways. They are more compact, more rugged, and they
take much better advantage of the PC board to allow them to get
rid of any heat they generate. Using them wherever appropriate
allows the advantages associated with discrete circuitry to be
retained while also providing room for both highly advanced
processing features and generous PC board copper paths where
needed. Their short lead-out structures allow maximum audio
performance and highest signal-to-noise ratios to be obtained in
amplifiers of desirable package size without resorting to “ampli-
fier-on-a-chip” shortcuts. These advantages are shown below in
Figure 1.

THE RESULT: Fewer connections, improved reliability, shorter
signal paths, superior signal-to-noise ratio and awesome sonic
performance.

N XCard (Internal Crossover)
The Punch and Power amplifiers utilize internal active crossovers.
These crossovers have many performance advantages such as using
discrete components for exact frequency adjustments which are far
superior to potentiometers. Additionally, the XCard can be config-
ured for high-pass, low-pass and full range operation. With slight
modifications, manycrossoverfrequenciesand slope configurations
can be achieved.
THE RESULT: Increased system design flexibility with a precise
electronic crossover without the limitations of conventional poten-
tiometer designs.
N MOSFET Devices
Rockford Fosgate is one of the few manufacturers in the sound
community to utilize MOSFET devices in both the power supply
and the output stages. MOSFET (Metal Oxide Semiconductor
Field Effect Transistor) devices offer several important inherent
advantages over the 30 year old technology of bi-polar design.
These advantages include: thermal stability, switching speed,
ultra low output impedance and wider bandwidth linearity. In
addition, MOSFETs and vacuum tubes share many important
operating characteristics. However, the MOSFET device is much
faster, wider in bandwidth, measurably lower in distortion and far
more linear than vacuum tubes.
THE RESULT: Operational characteristics of vacuum tubes
without the performance limitations of tube design.

DESIGN FEATURES
1. Cast Aluminum Heatsink – The cast aluminum heatsink of the
Punch amplifier dissipates heat generated by the amplifier's
circuitry. The inherent advantage of casting provides a 30%
improvement of cooling over conventional extrusion heatsink
designs.
2. End Caps – Interchangeable end caps conceal the wiring and
input cables, giving the amplifier a clean “stealth” look.

acoustical deficiencies of the listening environment. The Bass
control allows a narrow band adjustment of up to 18dB
centered at 45Hz. The Treble control is a wide band hinged
adjustment with a maximum of 18dB at 20kHz. The Punch EQ
can be bypassed by turning the controls to their minimum or
counterclockwise position.
9. LED Power Indicator – The LED illuminates when the unit is
turned on.
10. XCard (Internal Crossover) – This built-in crossover card is
configurable for a multitude of operating frequencies. The

IN STALLAT I O N C O N SI D ERAT I O N S
The following is a list of tools you will need for installing the Punch
amplifier:
Allen wrenches 7/64" & 3/32" (included) Voltmeter
Wire strippers
Electric hand drill w/assorted bits
Wire crimpers
Battery post wrench
Wire cutters
Assorted connectors
This section focuses on some of the vehicle considerations for
installing your new Punch amplifier. Checking your battery and
present sound system, as well as pre-planning your system layout and
best wiring routes will save installation time. When deciding how to
lay out your new system, be sure that each component will be easily
accessible for making adjustments.
Before beginninganyinstallation, be sure to follow these simple rules:
1. Be sure to carefully read and understand the instructions before
attempting to install the amplifier.
2. For safety, disconnect the negative lead from the battery prior to
beginning the installation.
3. For easier assembly, we suggest you run all wires prior to
mounting your amplifier in place.
4. Route all of the RCA cables close together and away from any
high current wires.
5. Use high quality connectors for a reliable installation and to
minimize signal or power loss.
6. Think before you drill! Be careful not to cut or drill into gas tanks,
fuel lines, brake or hydraulic lines, vacuum lines or electrical
wiring when working on any vehicle.
7. Never run wires underneath the vehicle. Running the wires
inside the vehicle provides the best protection.
8. Avoid running wires over or through sharp edges. Use rubber or
plastic grommets to protect any wires routed through metal,
especially the firewall.
9. ALWAYS protect the battery and electrical system from damage
with proper fusing. Install a fuseholder and appropriate fuse on
the +12V power wire within 18” (45.7 cm) of the battery terminal.
10. When grounding to the chassis of the vehicle, scrape all paint
from the metal to ensure a good, clean ground connection.
Groundingconnectionsshould be asshortaspossible and always
be connected to metal that is welded to the main body, or chassis,
of the vehicle.

MO UNTING LO CATIO N
The mountinglocation and position ofyouramplifierwillhave a great
effect on its ability to dissipate the heat generated during normal
operation. The design of our cast aluminum heatsink serves to easily
dissipate the heat generated over a wide range of operating condi-
tions. However, to maximize the performance of your amplifier, care
should be taken to ensure adequate ventilation.
Trunk Mounting
Mounting the amplifier vertically on a surface with the fin grooves
running up and down will provide the best cooling of the amplifier.
Mountingthe amplifieron the floorofthe trunkwillworkbutprovides
less cooling capability than vertical mounting.
Mounting the amplifier upside down to the rear deck of the trunk will
not provide proper cooling and will severely affect the performance
of the amplifier and is strongly not recommended.
Passenger Compartment Mounting
Mounting the amplifier in the passenger compartment will work as
long as you provide a sufficient amount of air for the amplifier to cool
itself. If you are going to mount the amplifier under the seat of the
vehicle, you must have at least 1" (2.54cm) of air gap around the
amplifier's heatsink.
Mounting the amplifier with less than 1" (2.54cm) of air gap around
the amplifier's heatsink in the passenger compartment will not
provide propercoolingand willseverelyaffectthe performance ofthe
amplifier and is strongly not recommended.
Engine Compartment Mounting
Rockford Fosgate amplifiers should never be mounted in the engine
compartment. Not only will this void your warranty but could create
an embarrassing situation caused by the ridicule from your friends.

BATTERY AN D CH ARG IN G
Amplifiers will put an increased load on the vehicle's battery and
charging system. We recommend checking your alternator and
battery condition to ensure that the electrical system has enough
capacity to handle the increased load of your stereo system. Stock
electrical systems which are in good condition should be able to
handle the extra load of any Rockford amplifier without problems,
although battery and alternator life can be reduced slightly. To
maximize the performance of your Rockford Fosgate amplifier, we
suggest the use of a heavy duty battery, high output alternator and an
energy storage capacitor.
W I R I N G T H E SYST E M
CAUTION: Avoid running power wires near the low level input
cables, antenna, power leads, sensitive equipment or harnesses. The
power wires carry substantial current and could induce noise into the
audio system.
• For safety, disconnect the negative lead from the battery prior to
beginning the installation.
1. Plan the wire routing. Take care when running signal level RCA
cablesto keep them close togetherbutisolated from the amplifier's
power cables and any high power auto accessories, especially
electric motors. This is done to prevent coupling the noise from
radiated electrical fields into the audio signal. When feeding the
wires through the firewall or any metal barrier, protect them with
plastic or rubber grommets to prevent short circuits. Leave the
wires long at this point to adjust for a precise fit at a later time.
2. Prepare the Power cable for attachment to the amplifier by
stripping 5/8" of insulation from the end of the wire. The use of 8
gauge power cable can interfere with the installation of the end
caps. Proper wire dress can prevent this from occurring. To
prevent the wire from fraying, strip the insulation at a 45° angle.
Insert the bared wire into the B+ terminal with the long side of the
insulation on the top. Bend the cable down at a 90° angle. Tighten
the set screw to secure the cable in place.

Punch 40ix, 60ix, 100ix
Trim the powercable to within 18"ofthe batteryand installthe
protective rubber boot, which is packed with the fuseholder,
over the end of the wire. Strip 3/8" of insulation from the wire
and insert into the end of the fuseholder, then crimp it in place.
Slide the rubber boot into place to cover the connection. Use
the section of cable that was trimmed earlier and connect it to
the other end of the fuseholder.
Punch 200ix
Mount the fuseholder within 18" of the battery using two (2) #8
screws. Disassemble the fuseholder. You should have 2 black
plastic end caps, 2 gold-plated fuse clips, a plastic spacer and
the fuseholder body. Trim the amplifier power cable to reach
the fuseholder and strip the wire 3/8". Slide one of the end caps
over the wire (narrow end first) and insert the wire into one of
the fuse clips. Tighten the set screw. Screw the black end cap
to the fuseholder body to secure the cable. Use the section of
cable that was trimmed earlier and connect it to the other end
of the fuseholder. Install the plastic spacer in the fuseholder
and attach the cable to the fuseholder body.
NOTE: The B+ cable MUST be fused 18" or less from the
vehicle's battery. Install the fuseholder under the hood and
prepare the cable ends as stated above. Connections should
be water tight.
3. Strip 3/8" from the battery end of the power cable and crimp
the large ring terminal to the cable. Use the ring terminal to
connect to the battery positive terminal. Do not install the fuse
at this time.
4. Prepare a length ofcable to be used forthe ground connection.
Strip 5/8" of insulation from the end of the cable as described
previously and connect to the appropriate terminal of the
amplifier. Prepare the chassis ground by scraping any paint
from the metal surface and thoroughly clean the area of all dirt
and grease. Strip the other end of the wire and attach a ring
connector. Fasten the cable to the chassis using a non-
anodized screw and star washers.

5. Prepare the REM turn-on wire for connection to the amplifier
by stripping 5/8" of insulation from the wire end and crimping
an insulated spade connector in place. Slide the connector
over the REM terminal on the amplifier. Connect the other end
of the REM wire to a switched 12 volt positive source. The
switched signal is usually taken from the source unit's auto
antenna or the accessory lead. If the source unit does not have
these outputs available, the recommended solution is to wire
a mechanical switch in line with a 12 volt source to activate
the amplifier.
6. Connectthe source signalto the amplifierbypluggingthe RCA
cables into the input jacks at the amplifier.
7. Connect the speakers. Strip the speaker wires 5/8" and insert
into the appropriate terminal on the amplifier. Insert the bared
wire into the speaker terminal and tighten the set screw to
secure into place. Be sure to maintain proper speaker polarity.
DO NOT chassis ground any of the speaker leads as unstable
operation may result.
8. Perform a finalcheckofthe completed system wiringto ensure
that all connections are accurate. Check all power and ground
connections for frayed wires and loose connections which
could cause problems.
9. After the final inspection is complete, install the power fuse
and enjoy listening. During the initial listening period, you
may need to “fine tune” any phasing and level settings within
your particular vehicle. To aid in this procedure, play a track
with high musical content and cruise around your neighbor-
hood. After fully evaluating the transient response of your
system and making any final adjustments, all your neighbors
within a 1 mile radius will assume that you have just success-
fully completed another upgrade to your audio system for
which they will probably spill thumbtacks on your driveway.

About the Dynamic Power Measurements
The Audio Graph PowerCube is a test instrument used to measure the
output of an amplifier in accordance with IHF-202 industry stan-
dards. The IHF-202 standard is a dynamic power measurement and
was developed as a means of measuring power in a manner that best
represents the Real World operation of an amplifier. Many manufac-
turers, including Rockford Fosgate, at times will measure amplifier
power into a fixed resistor (4 Ohm, 2 Ohm). While this method is
useful in some types of evaluation and testing, it is not representative
of an amplifier that is connected to a speaker and playing music.
Music
Music is dynamic; the sound waves are complex and constantly
changing. In order to simulate this, the IHF-202 standard calls for the
input signal to the amplifier to be a 1kHz bursted tone. This signal is
input (on for 20 milliseconds) and reduced 20dB for 480 millisec-
onds. The signal is gradually increased in level until the amplifier's
output exceeds 1% Total Harmonic Distortion (THD). At 1% distor-
tion becomes audible, therefore, any power produced above that
level is considered not usable. Many manufacturers represent their
amplifiers' output power in excess of 10% distortion. They use many
names for this measurement, such as Total Maximum Power or
Maximum Output Power. This is not indicative of the actual usable
output power.
Listening to Loudspeakers - Not Resistors
A loudspeaker is not a resistor. A resistor's value (resistance measured
in ohms) is fixed. A loudspeaker's impedance is dynamic. It is
constantly changing in value, dependent upon the frequency of the
input signal. Therefore, measuring power with the amplifier loaded
into a 4 ohm resistor is not the same as measuring power with the
amplifier connected to a 4 ohm speaker. Most people do not listen to
music through a resistor.
A4 Ohm speakermayexperience a drop in impedance 4-6 timeslower
than its nominal (printed) impedance. A speaker will also create phase
shifts in the signal that is passed through it. These phase shifts happen
because a speaker is an inductor (voice coil) and a capacitor (compli-
ance of the surround/spider), as well as a resistor (voice coil wire).
To simulate a speaker the Audio Graph PowerCube measures output
power into 20 different loads. It tests at 8 Ohms, 4 Ohms, 2 Ohms and
1 Ohm. Each ofthese impedancesisalso tested at–60°, –30°, 0°, +30°
and +60° phase angles. These different impedances and phase angles
representthe shiftsin impedance and phase thatcan occurin a typical
loudspeaker.

Information Cubed
The data acquired in the testing procedure is then graphed in the form
of a 3-dimensional cube. Hence the name PowerCube.
The Phase Angle is expressed on the horizontal axis, the Output
Voltage is presented on the vertical axis and the Impedance is
displayed on the Z axis. Output Power, in watts, is listed on the left
hand side for each impedance at each phase angle.

What is an Amplifier?
An amplifier by definition is a voltage generating device, recreating
the signal which is input to it identically but with increased volume.
It will be connected to a reactive load (the speaker). The impedance
of this load and phase of the signal passing through the load will vary,
dependent upon the frequency of the input signal (music).
Therefore, a perfect amplifier will be able to maintain the same output
voltage regardless of load characteristics and will not alter the signal
it is reproducing. A perfect amplifier when measured by the
AudioGraph PowerCube would present data that forms a perfect
cube. Unfortunately, amplifiers are not perfect. The laws of physics
generally prevent it. A great amplifier is about the best one can hope
to attain.
As you can see by the PowerCube and as you will experience by
listening, your Punch amplifier is a GREAT AMPLIFIER!
