– 1 – I NTRODUCTION 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[...]

– 2 – R OCKFORD F OSGA TE A CCESSORIES 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 caus[...]

– 3 – T ECHNICAL D ESIGN F EA TURES ◆ TOP AZ (T racking Operation Pre-Amplifier Zone) The TOPAZ ( T racking O peration P re- A mplifier Z one) 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 gro[...]

– 4 – ◆ 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 co[...]

– 5 – ◆ 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 o[...]

D ESIGN F EA TURES 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 ca[...]

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 level[...]

I NST ALLA TION C ONSIDERA TIONS – 8 – 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 [...]

M OUNTING L OCA TION – 9 – 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 [...]

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[...]

– 11 – 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 [...]

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 [...]

– 13 – U SING THE XC ARD 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 [...]
