Rockford engineers designed the Punch 40x2, 60x2, 100x2 and200x2 amplifiers to withstand the rugged automotive environmentwhile delivering superior sound quality in a flexible, reliable, andefficient package. TRANS•ANA is a low voltage circuit in the preampstage of all Punch x2 amplifiers that lets the music sound crystal clearand very real, even when played at high volume levels. This ismatched with TOPAZ, a unique grounding circuit used to eliminatenoise problems associated with car audio systems and their installa-tion. Flexibility is accomplished with the use of a built-in XCard.Reliability is all but guaranteed with the use of a protection circuitcalled NOMAD, while MOSFET and DSM (Discrete Surface Mount)technology improve amplifier efficiency. The result of these compo-nents give the Punch amplifier awesome sound quality in a “BulletProof” package. An explanation of these technologies, most of whichare exclusively designed and patented by Rockford, are described inthe Technical Design Features.

TRANS•ANA(TRANSconductance Active Nodal Amplifier)
The TRANS•ANA (TRANSconductance Active Nodal Amplifier) is acircuit that allows the audio signal to pass through the amplifier at lowvoltage. The signal is directly level-shifted to the fixed high voltagerails via a pair of driver transistors. Signal linearity is assured by anactive node formed by the drive transistors at ultrasonic frequencies.This allows amplifier performance similar to trans•nova which ishighly stable and linear while utilizing the advantages of a non-floating power supply.
THE RESULT: An extended frequency bandwidth accurately suppliedto the output stages of the amplifier.
TOPAZ (Tracking Operation Pre-Amplifier Zone)
The TOPAZ (Tracking Operation Pre-Amplifier Zone) circuitry solvesground loop noise problems common to automotive amplifier design.This innovative new development allows vastly improved isolation ofthe input signal grounds from the power supply ground of theamplifier. This is accomplished by allowing the source unit to controlthe potential “environment” of the entire input structure or “zone” ofthe amplifier. This process improves the noise rejection of the ampli-fier by 30-40dB – an astounding 30-100 times better than amplifierswithout TOPAZ.
THE RESULT: Elimination of troublesome ground loop noise betweensource and amplifier.
DSM (Discrete Surface Mount) Technology
The DSM (Discrete Surface Mount) manufacturing process combinesthe advantages of both discrete components and integrated circuitry.Rockford Fosgate is the only American amplifier manufacturer to haveinvested millions into this process. DSM components differ fromconventional discrete components in different ways. They are morecompact, more rugged, and they efficiently dissipate generated heat.Using them wherever appropriate allows the advantages associatedwith discrete circuitry to be retained while also providing room forboth highly advanced processing features and generous PC boardcopper paths where needed. Their short lead-out structures allowmaximum audio performance and highest signal-to-noise ratios to beobtained in amplifiers of desirable package size without resorting to“amplifier-on-a-chip” shortcuts. These advantages are shown belowin Figure 1.
Figure 1
THE RESULT: Fewer connections, improved reliability, shorter signalpaths, superior signal-to-noise ratio and awesome sonic performance.
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 configuredfor high-pass, low-pass and full range operation. With slight modifi-cations, many crossover frequencies and slope configurations can beachieved.
THE RESULT: Increased system design flexibility with a preciseelectronic crossover without the limitations of conventional potenti-ometer designs.

MOSFET DevicesRockford Fosgate is one of the few manufacturers in the soundcommunity to utilize MOSFET devices in both the power supply andthe output stages. MOSFET (Metal Oxide Semiconductor Field EffectTransistor) devices offer several important inherent advantages overthe 30 year old technology of bi-polar design. These advantagesinclude: thermal stability, switching speed, ultra low output imped-ance and wider bandwidth linearity. In addition, MOSFETs operatevery similarly to vacuum tubes in which they are more linear than bi-polar transistors. However, MOSFETs can deliver the midrange claritywithout the limitations of transient response and high frequencyphase shifting normally associated with tube operation.
THE RESULT: Operational characteristics similar to vacuum tubeswithout the performance limitations of tube design.
NOMAD (NOn-Multiplying Advanced Decision)
The Punch and Power amplifiers use an analog computer process tomaximize safe output power under all operating conditions. Theinnovative NOMAD (NOn-Multiplying Advanced Decision) systemis the most sophisticated version of this technique ever used, bringingpreviously unavailable levels of accuracy, stability, temperatureimmunity and reliability to this critical process. NOMAD makesadvanced decisions based on device voltages to precisely control theawesome levels of current available in the output MOSFETs to safevalues – but only when absolutely needed.
THE RESULT: Extremely fast protection system that always protectsthe amplifier and never degrades the sound.

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 any highcurrent 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 wires insidethe 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.
MOUNTING LOCATION
The mounting location and position of your amplifier will have agreat effect 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 butprovides less 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 ofthe amplifier 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.

BATTERY AND CHARGING
– 9 –
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.
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 intothe audio system.
• For safety, disconnect the negative lead from the battery prior tobeginning the installation.
1. Configure the internal XCard crossovers prior to installation. Referto “Using the XCard” (page 12) for further information.
2. 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.
3. Prepare the Power cable for at-tachment to the amplifier by strip-ping 5/8" of insulation from theend of the wire. To prevent thewire from fraying, strip the insula-tion at a 45° angle. Insert the baredwire into the B+ terminal with thelong side of the insulation on thetop. Bend the cable down at a 90°angle. Tighten the set screw to secure the cable in place.

Punch 40x2, 60x2, 100x2Trim the power cable to within 18" of the battery and install theprotective rubber boot, which is packed with the fuseholder, overthe end of the wire. Strip 3/8" of insulation from the wire and insertinto the end of the fuseholder, then crimp it in place. Slide therubber boot into place to cover the connection. Use the section ofcable that was trimmed earlier and connect it to the other end ofthe fuseholder.
Punch 200x2Mount 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 and thefuseholder body. Trim the amplifier power cable to reach thefuseholder and strip the wire 3/8". Slide one of the end caps overthe wire (narrow end first) and insert the wire into one of the fuseclips. Tighten the set screw. Screw the black end cap to thefuseholder body to secure the cable. Use the section of cable thatwas trimmed earlier and connect it to the other end of thefuseholder. Install the plastic spacer in the fuseholder and attachthe cable to the fuseholder body.
NOTE: The B+ cable MUST be fused 18" or less from the vehicle'sbattery. Install the fuseholder under the hood and prepare thecable ends as stated above. Connections should be water tight.
4. Strip 3/8" from the battery end of the power cable and crimp a largering terminal to the cable. Use the ring terminal to connect to thebattery positive terminal. Do not install the fuse at this time.
5. 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 the ampli-fier. Prepare the chassis ground by scraping any paint from themetal surface and thoroughly clean the area of all dirt and grease.Strip the other end of the wire and attach a ring connector. Fastenthe cable to the chassis using a non-anodized screw and a starwasher.
6. Prepare the REM turn-on wire for connection to the amplifier bystripping 5/8" of insulation from the wire end and crimping aninsulated spade connector in place. Slide the connector over theREM terminal on the amplifier. Connect the other end of the REMwire to a switched 12 volt positive source. The switched signal isusually taken from the source unit's auto antenna or the accessorylead. If the source unit does not have these outputs available, therecommended solution is to wire a mechanical switch in line witha 12 volt source to activate the amplifier.
7. Securely mount the amplifier (with supplied screws) to the vehicleor amp rack. Be careful not to mount the amplifier on cardboardor plastic panels. Doing so may enable the screws to pull out fromthe panel due to road vibration or sudden vehicle stops.
8. Connect the source signal to the amplifier by plugging the RCAcables into the input jacks at the amplifier.
9. Connect the speakers. Strip the speaker wires 5/8" and insert intothe appropriate terminal on the amplifier. Insert the bared wireinto the speaker terminal and tighten the set screw to secure intoplace. Be sure to maintain proper speaker polarity. DO NOTchassis ground any of the speaker leads as unstable operationmay result.
10. 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 which couldcause problems.
11. After the final inspection is complete, install the power fuse andenjoy listening. During the initial listening period, you may needto “fine tune” any phasing and level settings within your particularvehicle. To aid in this procedure, play a track with high musicalcontent and cruise around your neighborhood. After fully evalu-ating the transient response of your system and making any finaladjustments, all your neighbors within a 1 mile radius will assumethat you have just successfully completed another upgrade to youraudio system for which they will probably spill thumbtacks onyour driveway.

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 standards. TheIHF-202 standard is a dynamic power measurement and was developedas a means of measuring power in a manner that best represents the RealWorld operation of an amplifier. Many manufacturers, including RockfordFosgate, at times will measure amplifier power into a fixed resistor (4 ohm,2 ohm). While this method is useful in some types of evaluation andtesting, it is not representative of an amplifier that is connected to a speakerand playing music.
MusicMusic is dynamic; the sound waves are complex and constantly changing.In order to simulate this, the IHF-202 standard calls for the input signal tothe amplifier to be a 1kHz bursted tone. This signal is input (on for 20milliseconds) and reduced 20dB for 480 milliseconds. The signal isgradually increased in level until the amplifier's output exceeds 1% TotalHarmonic Distortion (THD). At 1% distortion becomes audible, therefore,any power produced above that level is considered unusable. Manymanufacturers represent their amplifiers' output power in excess of 10%distortion. They use many names for this measurement, such as TotalMaximum Power or Maximum Output Power. This is not indicative of theactual usable output power.
Listening to Loudspeakers - Not ResistorsA loudspeaker is not a resistor. A resistor's value (resistance measured inohms) is fixed. A loudspeaker's impedance is dynamic. It is constantlychanging in value, dependent upon the frequency of the input signal.Therefore, measuring power with the amplifier loaded into a 4 ohmresistor is not the same as measuring power with the amplifier connectedto a 4 ohm speaker. Most people do not listen to music through a resistor.
A 4 ohm speaker may experience a drop in impedance 4-6 times lower thanits nominal (printed) impedance. A speaker will also create phase shifts inthe signal that is passed through it. These phase shifts happen because aspeaker is an inductor (voice coil) and a capacitor (compliance of thesurround/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 and 1ohm. Each of these impedances is also tested at –60°, –30°, 0°, +30° and+60° phase angles. These different impedances and phase angles repre-sent 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 the AudioGraph PowerCube would present data that forms a perfect cube.Unfortunately, amplifiers are not perfect. The laws of physics gener-ally prevent it. A great amplifier is about the best one can hope toattain.
As you can see by the PowerCube and as you will experience bylistening, your Punch amplifier is a GREAT AMPLIFIER!

Gli ingenieri Rockford hanno progettato la serie di amplificatori Punchx2 per resistere all'ostico ambiente automobilistico mentre suonano conuna musicalitá superiore, offrendo un insieme versatile, affidabile edefficiente. Trans•ana é un circuito a bassa tensione dello stadiopreamplificatore del Punch x2 che permette al suono di essere cristallinoe reale anche in presenza di volumi molto elevati…tutto questo éaccoppiato TOPAZ, un exclusivo circuito di massa impiegato pereliminare i problemi di rumore comunemente presenti negli impianti caraudio. Il massimo della versatilitá é raggiunto con l'impiego delle XCard.L'affidabilitá é completamente garantita dall'impiego di un circuito diprotezione chiamato NOMAD, mentre l'uso di MOSFET e della tecnologiaDSM (Discrete Surface Mount) permette di raggiungere efficienzeelevatissime. Il risultato finale di tutte queste tecnnologie moderne é chegli amplificatori Punch suonano meravigliosamente e sono indistruttibili,a “prova di proiettile.” Una spiegazione di queste tecnologie innovative,molte coperte da brevetti Rockford, sono descritte in un'altra sezione diquesto manuale.
INTRODUZIONE
Nel BagagliaioMontando l'amplificatore su una superficie in verticale con le alettedirezionate dall'alto verso il basso si garantirá un miglior raffreddamentodell'amplificatore.
Nell'abitacoloMontare l'amplificatore nell'abitacolo si avrá un funzionamento regolarese si garantisce un flusso d'aria sufficiente. Per l'installazione sotto unsedile, é necessario avere uno spazio di almeno 3 cm attorno a tuttol'amplificatore.
InstallazionePer sicurezza, scollegare il polo negativo della batteria dell'auto primadi iniziare l'installazione.
Terminale B+ (cavo positivo)Il cavo positivo deve essere protetto da un fusibile a non piú di 45 cmdalla batteria. Terminare il cavo e installare il fusibile nel vano motore.Tutte le connessioni devono essere a prova d'acqua.
DOVE POSIZIONARLO
– 41 –
Terminale GND (cavo negativo)Decidere la lunghezza del cavo e terminarlo. Preparare la massagrattando la vernice dal telaio dell'auto ed eliminando tracce di olioo sporco. Fissare il cavo di massa al telaio con una vite.
Terminale REM (Consenso di accensione)Collegare il cavo REM ad un positivo presente solo ad autoradioaccesa (normalmente il cavo pilota dell'antenna elettrica o il cavoaccessori dell'autoradio). Se la sorgente non dovesse essereequipaggiata con queste uscite, la soluzione raccomandabile é diinserire un interruttore su un cavo positivo e connettersiall'amplificatore.

Stereo/Mono Operation
• Ingressi RCA collegati sia al canale destro sia al sinistro• Gain (controllo di sensibilitá) regolati in modo identico per
bilanciare il subwoofer• L'impedenza di ciascun canale deve essere minimo 2Ω• L'impedenza per il canale mono deve essere minimo 4Ω• La scheda XCard deve essere in posizione Full Range• Nel funzionamento Stereo/Mono simultaneo devono essere
impiegati i crossover passivi• Non cortocircuitare a massa nessun cavo degli altoparlanti,
potrebbe portare ad un funzionamento irregolare
