INTRODUCTION 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 techn

ROCKFORD FOSGATE ACCESSORIES 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 amplifi

TECHNICAL DESIGN FEATURES 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 pr

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 the

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, many crossover frequencies and slope configurations can be achieved. THE RESULT: Increased system design flexibility with a

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. 3 8 7 6 6 7 8 3 Speaker Speaker +L – Left Left Right Right +R– Treble Gain Input Input Gain Bass 9 5 4 LED REM

6. RCA Input Jacks – The industry standard RCA jacks provide easy connections for signal level input. They are gold-plated to resist the signal degradation caused by corrosion. 7. Input Sensitivity Controls – The input level controls are preset for 825mV which will match the output of most source units. They can be adjusted to match input levels ranging from 150mV to 3V. 8. Punch Equalization Controls – The Punch EQ helps correct for acoustical deficiencies of the listening environment. Th

INSTALLATION CONSIDERATIONS 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 Battery post wrench Electric hand drill w/assorted bits Wire cutters Wire crimpers 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 s

MOUNTING LOCATION The mounting location and position of your amplifier will have 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

BATTERY AND CHARGING 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

Punch 40ix, 60ix, 100ix Trim the power cable to within 18" of the battery and install the 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

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 mech

USING THE XCARD The crossover functions are controlled through the use of an XCard and can be set for high-pass, low-pass or full range operation. Each crossover card has two faces: one face operates Full Range, the other has arrows to indicate the edge for selecting HP (high-pass) or LP (low-pass) operation. Orient the card with the desired operating edge, indicated by the arrow, toward the socket terminals inside the amplifier. Firmly, but carefully, plug the card into the socket. High-Pass Lo
