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

ROCKFORD FOSGATE ACCESSORIES
The following accessories were designed to enhance the perfor-mance of the Punch 2-channel amplifiers.
Energy Storage CapacitorThe Punch capacitors are used to provide extra current needed byamplifiers to reproduce musical transients. The Punch Caps alsohave the natural ability to filter AC ripple caused by the alternator,reducing the chance of noise in the system. The Punch Caps willmaximize both the sound quality and performance that RockfordFosgate amplifiers can deliver.
Punch Link (FG-LINK)The Punch Link is a specially cast heatsink interconnect whichallows you to join any of our current Punch or Punch Poweramplifiers together. While providing additional cooling throughthe coupling process, the Punch Link adds the finishing touch bygiving you the look of one awesome amplifier.

TECHNICAL DESIGN FEATURES
TOPAZ (Tracking Operation Pre-Amplifier Zone)
The TOPAZ (Tracking Operation Pre-Amplifier Zone) circuitrysolves ground loop noise problems common to automotiveamplifier design. This innovative new development allows vastlyimproved isolation of the input signal grounds from the powersupply ground of the amplifier. This is accomplished by allowingthe source unit to control the potential “environment” of theentire input structure or “zone” of the amplifier. This processimproves the noise rejection of the amplifier by 30-40dB – anastounding 30-100 times better than amplifiers without TOPAZ.
THE RESULT: Elimination of troublesome ground loop noisebetween source and amplifier.
RTP (Real Time Protection)NOMAD (NOn-Multiplying AdvancedDecision)
The Punch and Power amplifiers use an analog computerprocess to maximize safe output power under all operatingconditions. Rockford Fosgate pioneered and developed RTP(Real Time Protection), a crucial element in the performanceedge of our amplifiers. The innovative NOMAD (NOn-Multiply-ing Advanced Decision) system is the most sophisticated versionof this technique ever used, bringing previously unavailablelevels of accuracy, stability, temperature immunity and reliabil-ity to this critical process. NOMAD makes advanced decisionsbased on device voltages to precisely control the awesome levelsof current available in the output MOSFETs to safe values – butonly when absolutely needed.
THE RESULT: Extremely fast protection system that alwaysprotects the amplifier and never degrades the sound.

DSM (Discrete Surface Mount) Technology
The DSM (Discrete Surface Mount) manufacturing process com-bines the advantages of both discrete components and integratedcircuitry. 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 threedifferent ways. They are more compact, more rugged, and theytake much better advantage of the PC board to allow them to getrid of any heat they generate. Using them wherever appropriateallows the advantages associated with discrete circuitry to beretained while also providing room for both highly advancedprocessing features and generous PC board copper paths whereneeded. Their short lead-out structures allow maximum audioperformance and highest signal-to-noise ratios to be obtained inamplifiers of desirable package size without resorting to “ampli-fier-on-a-chip” shortcuts. These advantages are shown below inFigure 1.

XCard (Internal Crossover)
The Punch and Power amplifiers utilize internal active crossovers.These crossovers have many performance advantages such as usingdiscrete components for exact frequency adjustments which are farsuperior to potentiometers. Additionally, the XCard can be config-ured for high-pass, low-pass and full range operation. With slightmodifications, many crossover frequencies and slope configurationscan be achieved.
THE RESULT: Increased system design flexibility with a preciseelectronic crossover without the limitations of conventional poten-tiometer designs.
MOSFET DevicesRockford Fosgate is one of the few manufacturers in the soundcommunity to utilize MOSFET devices in both the power supplyand the output stages. MOSFET (Metal Oxide SemiconductorField Effect Transistor) devices offer several important inherentadvantages 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. Inaddition, MOSFETs and vacuum tubes share many importantoperating characteristics. However, the MOSFET device is muchfaster, wider in bandwidth, measurably lower in distortion and farmore linear than vacuum tubes.
THE RESULT: Operational characteristics of vacuum tubeswithout the performance limitations of tube design.
DESIGN FEATURES
1. Cast Aluminum Heatsink – The cast aluminum heatsink of thePunch amplifier dissipates heat generated by the amplifier'scircuitry. The inherent advantage of casting provides a 30%improvement of cooling over conventional extrusion heatsinkdesigns.
2. End Caps – Interchangeable end caps conceal the wiring andinput cables, giving the amplifier a clean “stealth” look.

INSTALLATION CONSIDERATIONS
– 8 –
This section focuses on some of the vehicle considerations forinstalling your new Punch amplifier. Checking your battery andpresent sound system, as well as pre-planning your system layout andbest wiring routes will save installation time. When deciding how tolay out your new system, be sure that each component will be easilyaccessible for making adjustments.
Before beginning any installation, be sure to follow these simple rules:
1. Be sure to carefully read and understand the instructions beforeattempting to install the amplifier.
2. For safety, disconnect the negative lead from the battery prior tobeginning the installation.
3. For easier assembly, we suggest you run all wires prior tomounting your amplifier in place.
4. Route all of the RCA cables close together and away from anyhigh current wires.
5. Use high quality connectors for a reliable installation and tominimize 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 electricalwiring when working on any vehicle.
7. Never run wires underneath the vehicle. Running the wiresinside the vehicle provides the best protection.
8. Avoid running wires over or through sharp edges. Use rubber orplastic grommets to protect any wires routed through metal,especially the firewall.
9. ALWAYS protect the battery and electrical system from damagewith proper fusing. Install a fuseholder and appropriate fuse onthe +12V power wire within 18” (45.7 cm) of the battery terminal.
10. When grounding to the chassis of the vehicle, scrape all paintfrom the metal to ensure a good, clean ground connection.Grounding connections should be as short as possible and alwaysbe connected to metal that is welded to the main body, or chassis,of the vehicle.
The following is a list of tools you will need for installing the Punchamplifier:
Allen wrenches 7/64" & 3/32" (included) VoltmeterWire strippers Battery post wrenchElectric hand drill w/assorted bits Wire cuttersWire crimpers Assorted connectors
MOUNTING LOCATION
– 9 –
The mounting location and position of your amplifier will have a greateffect on its ability to dissipate the heat generated during normaloperation. The design of our cast aluminum heatsink serves to easilydissipate the heat generated over a wide range of operating condi-tions. However, to maximize the performance of your amplifier, careshould be taken to ensure adequate ventilation.
Trunk MountingMounting the amplifier vertically on a surface with the fin groovesrunning up and down will provide the best cooling of the amplifier.
Mounting the amplifier on the floor of the trunk will work but providesless cooling capability than vertical mounting.
Mounting the amplifier upside down to the rear deck of the trunk willnot provide proper cooling and will severely affect the performanceof the amplifier and is strongly not recommended.
Passenger Compartment MountingMounting the amplifier in the passenger compartment will work aslong as you provide a sufficient amount of air for the amplifier to coolitself. If you are going to mount the amplifier under the seat of thevehicle, you must have at least 1" (2.54cm) of air gap around theamplifier's heatsink.
Mounting the amplifier with less than 1" (2.54cm) of air gap aroundthe amplifier's heatsink in the passenger compartment will notprovide proper cooling and will severely affect the performance of theamplifier and is strongly not recommended.
Engine Compartment MountingRockford Fosgate amplifiers should never be mounted in the enginecompartment. Not only will this void your warranty but could createan embarrassing situation caused by the ridicule from your friends.
Amplifiers will put an increased load on the vehicle's battery andcharging system. We recommend checking your alternator andbattery condition to ensure that the electrical system has enoughcapacity to handle the increased load of your stereo system. Stockelectrical systems which are in good condition should be able tohandle the extra load of any Rockford amplifier without problems,although battery and alternator life can be reduced slightly. Tomaximize the performance of your Rockford Fosgate amplifier, wesuggest the use of a heavy duty battery, high output alternator and anenergy storage capacitor.

BATTERY AND CHARGING
WIRING THE SYSTEM
CAUTION: Avoid running power wires near the low level inputcables, antenna, power leads, sensitive equipment or harnesses. Thepower wires carry substantial current and could induce noise into theaudio system.
• For safety, disconnect the negative lead from the battery prior tobeginning the installation.
1. Plan the wire routing. Take care when running signal level RCAcables to keep them close together but isolated from the amplifier'spower cables and any high power auto accessories, especiallyelectric motors. This is done to prevent coupling the noise fromradiated electrical fields into the audio signal. When feeding thewires through the firewall or any metal barrier, protect them withplastic or rubber grommets to prevent short circuits. Leave thewires long at this point to adjust for a precise fit at a later time.
2. Prepare the Power cable for attachment to the amplifier bystripping 5/8" of insulation from the end of the wire. The use of 8gauge power cable can interfere with the installation of the endcaps. Proper wire dress can prevent this from occurring. Toprevent the wire from fraying, strip the insulation at a 45° angle.Insert the bared wire into the B+ terminal with the long side of theinsulation on the top. Bend the cable down at a 90° angle. Tightenthe set screw to secure the cable in place.
– 11 –
Punch 40ix, 60ix, 100ixTrim the power cable to within 18" of the battery and install theprotective rubber boot, which is packed with the fuseholder,over the end of the wire. Strip 3/8" of insulation from the wireand insert into the end of the fuseholder, then crimp it in place.Slide the rubber boot into place to cover the connection. Usethe section of cable that was trimmed earlier and connect it tothe other end of the fuseholder.
Punch 200ixMount the fuseholder within 18" of the battery using two (2) #8screws. Disassemble the fuseholder. You should have 2 blackplastic end caps, 2 gold-plated fuse clips, a plastic spacer andthe fuseholder body. Trim the amplifier power cable to reachthe fuseholder and strip the wire 3/8". Slide one of the end capsover the wire (narrow end first) and insert the wire into one ofthe fuse clips. Tighten the set screw. Screw the black end capto the fuseholder body to secure the cable. Use the section ofcable that was trimmed earlier and connect it to the other endof the fuseholder. Install the plastic spacer in the fuseholderand attach the cable to the fuseholder body.
NOTE: The B+ cable MUST be fused 18" or less from thevehicle's battery. Install the fuseholder under the hood andprepare the cable ends as stated above. Connections shouldbe water tight.
3. Strip 3/8" from the battery end of the power cable and crimpthe large ring terminal to the cable. Use the ring terminal toconnect to the battery positive terminal. Do not install the fuseat this time.
4. Prepare a length of cable to be used for the ground connection.Strip 5/8" of insulation from the end of the cable as describedpreviously and connect to the appropriate terminal of theamplifier. Prepare the chassis ground by scraping any paintfrom the metal surface and thoroughly clean the area of all dirtand grease. Strip the other end of the wire and attach a ringconnector. 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 amplifierby stripping 5/8" of insulation from the wire end and crimpingan insulated spade connector in place. Slide the connectorover the REM terminal on the amplifier. Connect the other endof the REM wire to a switched 12 volt positive source. Theswitched signal is usually taken from the source unit's autoantenna or the accessory lead. If the source unit does not havethese outputs available, the recommended solution is to wirea mechanical switch in line with a 12 volt source to activatethe amplifier.
6. Connect the source signal to the amplifier by plugging the RCAcables into the input jacks at the amplifier.
7. Connect the speakers. Strip the speaker wires 5/8" and insertinto the appropriate terminal on the amplifier. Insert the baredwire into the speaker terminal and tighten the set screw tosecure into place. Be sure to maintain proper speaker polarity.DO NOT chassis ground any of the speaker leads as unstableoperation may result.
8. Perform a final check of the completed system wiring to ensurethat all connections are accurate. Check all power and groundconnections for frayed wires and loose connections whichcould cause problems.
9. After the final inspection is complete, install the power fuseand enjoy listening. During the initial listening period, youmay need to “fine tune” any phasing and level settings withinyour particular vehicle. To aid in this procedure, play a trackwith high musical content and cruise around your neighbor-hood. After fully evaluating the transient response of yoursystem and making any final adjustments, all your neighborswithin a 1 mile radius will assume that you have just success-fully completed another upgrade to your audio system forwhich they will probably spill thumbtacks on your driveway.

USING THE XCARD
The crossover functions are controlled through the use of anXCard and can be set for high-pass, low-pass or full rangeoperation. Each crossover card has two faces: one face operatesFull Range, the other has arrows to indicate the edge for selectingHP (high-pass) or LP (low-pass) operation. Orient the card withthe desired operating edge, indicated by the arrow, toward thesocket terminals inside the amplifier. Firmly, but carefully, plugthe card into the socket.
The crossover point can be altered by changing the resistor value.Use the following formula to select the appropriate resistor valueto be placed on the XCard.

DYNAMIC POWER MEASUREMENTS
About the Dynamic Power MeasurementsThe Audio Graph PowerCube is a test instrument used to measure theoutput of an amplifier in accordance with IHF-202 industry stan-dards. The IHF-202 standard is a dynamic power measurement andwas developed as a means of measuring power in a manner that bestrepresents the Real World operation of an amplifier. Many manufac-turers, including Rockford Fosgate, at times will measure amplifierpower into a fixed resistor (4 Ohm, 2 Ohm). While this method isuseful in some types of evaluation and testing, it is not representativeof an amplifier that is connected to a speaker and playing music.
MusicMusic is dynamic; the sound waves are complex and constantlychanging. In order to simulate this, the IHF-202 standard calls for theinput signal to the amplifier to be a 1kHz bursted tone. This signal isinput (on for 20 milliseconds) and reduced 20dB for 480 millisec-onds. The signal is gradually increased in level until the amplifier'soutput exceeds 1% Total Harmonic Distortion (THD). At 1% distor-tion becomes audible, therefore, any power produced above thatlevel is considered not usable. Many manufacturers represent theiramplifiers' output power in excess of 10% distortion. They use manynames for this measurement, such as Total Maximum Power orMaximum Output Power. This is not indicative of the actual usableoutput power.
Listening to Loudspeakers - Not ResistorsA loudspeaker is not a resistor. A resistor's value (resistance measuredin ohms) is fixed. A loudspeaker's impedance is dynamic. It isconstantly changing in value, dependent upon the frequency of theinput signal. Therefore, measuring power with the amplifier loadedinto a 4 ohm resistor is not the same as measuring power with theamplifier connected to a 4 ohm speaker. Most people do not listen tomusic through a resistor.
A 4 Ohm speaker may experience a drop in impedance 4-6 times lowerthan its nominal (printed) impedance. A speaker will also create phaseshifts in the signal that is passed through it. These phase shifts happenbecause 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 outputpower into 20 different loads. It tests at 8 Ohms, 4 Ohms, 2 Ohms and1 Ohm. Each of these impedances is also tested at –60°, –30°, 0°, +30°and +60° phase angles. These different impedances and phase anglesrepresent the shifts in impedance and phase that can occur in a typicalloudspeaker.
Information CubedThe data acquired in the testing procedure is then graphed in the formof a 3-dimensional cube. Hence the name PowerCube.
The Phase Angle is expressed on the horizontal axis, the OutputVoltage is presented on the vertical axis and the Impedance isdisplayed on the Z axis. Output Power, in watts, is listed on the lefthand side for each impedance at each phase angle.
What is an Amplifier?An amplifier by definition is a voltage generating device, recreatingthe signal which is input to it identically but with increased volume.It will be connected to a reactive load (the speaker). The impedanceof 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 outputvoltage regardless of load characteristics and will not alter the signalit is reproducing. A perfect amplifier when measured by theAudioGraph PowerCube would present data that forms a perfectcube. Unfortunately, amplifiers are not perfect. The laws of physicsgenerally prevent it. A great amplifier is about the best one can hopeto attain.
As you can see by the PowerCube and as you will experience bylistening, your Punch amplifier is a GREAT AMPLIFIER!
