We, at Rockford Fosgate, have worked very hard to make sure all the information in this manual is current. But, as we are constantly finding new ways to improve our product, this information is subject to change without notice. -
Page 4: Introduction
N T R O D U C T I O N This manual provides information on the features, installation and opera- tion of the Rockford Fosgate 2.3, 2.6x and 4.6x Amplifiers. We suggest you save this manual for future reference. - Page 5 THE RESULT: Elimination of troublesome ground loop noise between source and amplifier. MOSFET Devices Rockford Fosgate is one of the few manufacturers in the sound community to utilize MOSFET devices in both the power supply and the output stages . MOSFET (Metal Oxide Semiconductor Field Effect Transistor) devices offer several important inherent advantages over the 30 year old technology of bi-polar design.
- Page 6 The DSM (Discrete Surface Mount) manufacturing process combines the advantages of both discrete components and integrated circuitry. Rockford Fosgate is the only American amplifier manufacturer to have invested millions into this process. DSM components differ from conventional discrete components in different ways. They are more compact, more rugged, and they efficiently dissipate generated heat.
- Page 7 High Level Inputs The high level inputs on the Rockford Fosgate amplifiers convert the speaker line outputs (high level) to preamp line inputs (low level). This allows amplifier compatibility with a variety of source units as well as the ability to integrate into factory systems without the need for external adapters.

Extruded Heatsink The extruded aluminum heatsink of the RF amplifier dissipates heat generated by the amplifier's circuitry. 2. Power/Speaker Barrier Strip The barrier strip uses screw terminals that will accept #10 spade lugs or bare speaker and power wire sizes from 10-18 AWG. These gold-plated connectors are immune to corrosion that will cause signal degradation.

Rockford amplifier without problems, although battery and alternator life can be reduced slightly. To maximize the performance of your Rockford Fosgate amplifier, we suggest the use of a heavy duty battery, high output alternator and an energy storage capacitor. - Page 13 Trim the power cable within 18" of the battery and strip 1/2" of insulation from the end of the wire. here Cut the wire loop that is attached to the fuseholder in half and splice the fuse into the power line using appropriate inline connectors.

Page 16: Using The Xcard
S I N G T H E The crossover functions are controlled through the use of an XCard and can be set for high-pass, low-pass or full range operation. The 100Hz XCard shipped with your amplifier is set for Full Range. 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. -
Page 17: Resistor Chart
ESISTOR HART Our tests have shown that using 0.047 f capacitors for frequencies below 100Hz, and 0.022 f capacitors for frequencies above 100Hz, result in more linear crossover control. Refer to the Specifications page to determine the capacitor value of each supplied XCard. -
