P U N C H 2X/3X/5X P A C K I N G L I S T Punch Electronic Crossover Owner's Manual INTRODUCTION This manual provides information on the features, installation and operation of the Punch 2X, 3X and 5X Electronic Crossover. We suggest you save this manual for future reference. We strongly recommend you have your Authorized Rockford Fosgate Dealer install your new active crossover. If you do choose to install the unit yourself, please be sure to read the entire manual before beginning your installation.
D E S I G N F E AT U R E S REMOVING THE COVER The design of the 2X, 3X and 5X allows the cover to be removed for access to the crossovers and ease of installation. The cover can be installed in either direction to match the rest of the system. The top end of the cover has two tabs which fit snugly into slots at either end of the base. Care must be taken not to bend the securing tabs when removing the top cover. A screw secures the cover. Remove this screw to release the cover for removal.

Gold Plated RCA Jacks All input and output RCA jacks are gold plated. The gold plated finish resists tarnishing and corrosion from interfering with the signal quality. 2. Power Terminals The B+, Rem and Gnd connections are made using gold plated screw terminals on the barrier strip.
6. Phase Switch (3X and 5X only) The phase switch allows easy invertion polarity on the non-faded output to optimize sound quality. 7. Mounting Holes The crossover must be mounted on a flat surface. Two mounting holes in the bottom are used to secure the crossover. 8. Fusing The crossover has a 1/2 amp AGC fast blow power protection fuse. If it is necessary to replace the fuse, use only the same type and rating or the warranty may be voided.
I N S TA L L A T I O N C O N S I D E R A T I O N S This section focuses on some of the vehicle considerations for installing your new Punch Electronic Crossover. Checking your battery and current 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 beginning any installation, be sure to follow these simple rules: 1.
MOUNTING AND WIRING THE ELECTRONIC CROSSOVERS The information below describes the various considerations for mounting and connecting the active crossovers. For additional information see the wiring diagrams beginning on page 10. We recommend mounting the crossover as close to the amplifier(s) as possible. The B+ (Power) supplies power to the unit. Connect this terminal to a constant +12 Volt power source by way of an in-line fuse. The GND (Power Ground) grounds the unit.
S ELECT I N G T HE PROC A RDS The Punch 2X is shipped with 100Hz cards. The 3X is shipped with 100Hz and blank programmable cards and the 5X is shipped with 100Hz, 6.5kHz and blank programmable cards. The following cards are available factory built from your Authorized Rockford Fosgate Dealer. XM50 XM70 XM100 XM150 XM200 XM275 XM400 XM4.5k XM6.5k 50Hz 70Hz 100Hz 150Hz 200Hz 275Hz 400Hz 4.5kHz 6.5kHz Each card can be used for high-pass, low-pass or full range operation.

The Dual Filter is a two stage cascaded filter which uses two PROCards. The first card determines the initial action and the second, the subsequent action.
F I LT E R EF F E C T S Example: The Punch 3X ships with three (3) 100Hz PROCards set in the Full Range position. The crossover will pass through all 20Hz 20kHz frequencies. The following diagram shows examples of the types of response curves when programming for a High-Pass, LowPass or Bandpass setting.

APPENDIX A B UILDING A C USTOM PROC ARD The 3X and 5X both ship with blank cards which can be assembled to select any frequency you need for your system's design. Each card is built using 4 capacitors and 4 resistors, the value of the resistors determines the operating frequency. The custom cards are also available as model number XM00 from your Authorized Rockford Fosgate Dealer. The following section has instructions on assembling the card.
