INTRODUCTION This manual provides information on the features, installation and operation of the Series 1 2300, 2600x and 4600x Amplifiers. We suggest you save this manual for future reference. We strongly recommend you have your Authorized Rockford Fosgate Dealer and Service Center install your new Series 1 amplifier. If you do choose to install your Series 1 amplifier yourself, please be sure to read the entire manual before beginning.

Power/Speaker Connectors The gold-plated terminal block connectors are: GND Supplies ground to the amplifier. AP The amplifier is turned on by connecting the remote turnon wire to the source unit's “Auto Antenna” or remote turn-on lead, either of which should go to +12 volts when the source unit is activated. B+ Supplies power to the amplifier.
I N S TA L L AT I O N C O N S I D E R AT I O N S This section focuses on some of the vehicle considerations for installing your new Series 1 amplifier. 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.
TOOLS & SUPPLIES NEEDED Wire Cutters Wire Strippers Wire Crimpers Voltmeter Phillips Screwdrivers Flat Blade Screwdrivers Battery Post Wrench Electric Hand Drill with assorted bits Power Wire - [10-12 AWG; approx. 17’ (518.72 cm)] Grounding Wire - [10-12 AWG.; max. length 1.5’ (45.72 cm)] Remote (AP) Turn-On Wire - [18 AWG; approx. 12’ (365.76 cm)] Assorted wire connectors In-line butt connectors that match power and ground wire AWG 3/8" (.953cm) Battery Ring Terminal 1/4" (.
PASSENGER MOUNTING Under the seat or floor mounting will work as long as there is a minimum of 1” (2.5 cm) of air gap above the amplifier heatsink. Vertical mounting of the amplifier is still the best. WIRING THE SERIES 1 Caution! Be sure to avoid running the power wires near the low level input cables, antenna, sensitive equipment or harnesses. The power wires carry substantial currents and could induce noise. 1.
4. Input – The amplifier’s signal input RCA jacks should be connected to the source unit’s signal outputs with high-quality braided or double-shielded interconnecting RCA cables. Note: Be sure to route the Series 1 signal input cable away from the main power wire and the car’s wiring harnesses to avoid noise coupling. If the source unit does not utilize RCA cables, connect the left and right positive speaker output wires from the source unit to the amplifier’s High Level Speaker Input Connector.
ACTIVE CROSSOVER MODE SELECTIONS FOR THE 2600X AND 4600X The Series 1 2600x and the 4600x amplifiers feature a selectable electronic crossover. One module controls two output channels that can be configured in a High-Pass, Low-Pass, or Full Range (factory default) position. (Note: The 4600x has 2 modules as it is a 4-channel amplifier). Selection is made by positioning a removable module card. Both the 2600x and 4600x are shipped with 100Hz 12dB per octave Butterworth aligned crossover modules.

TROUBLESHOOTING This troubleshooting guide is intended to assist you with certain problems which may occur. If you still encounter problems, see your Authorized Rockford Dealer for assistance. Problem Amplifier will not play — Remote Turn-on light is off. Solution 1. Check the DC voltage at the amplifier’s B+ terminal with a voltmeter. The voltage should measure between 11.5V - 15.5V. If voltage is not found, check the battery, fuse, fuse housing and wire connections. Fix, repair, or replace accordingly. 2.
Problem Amplifier gets too hot. Solution 1. Be sure the amplifier is properly mounted. You should be able to place your hand a few inches above the amplifier housing and feel the heat rising when the unit is on. Hot air rises. Consequently mount the amplifier with the heatsink fins aligned vertically. This allows the air to flow freely, carrying away the heat. Check to see that the heatsink fins are free of any obstruction (i.e., carpet, seats, etc.). 2.
Problem Engine Noise (Whine) Solution 1. Disconnect the speakers from the amplifier. Connect a test speaker to the amplifier output terminals. If the noise goes away, check your speaker leads, speakers and crossovers. 2. If the noise persists, use a “shorting plug” to mute the input signal at the amplifier. If the noise goes away: a. Bypass all of the other equipment (i.e., crossovers and equalizers) and connect the head unit directly to the amp.
D YNAMIC P OWER M EASUREMENTS About the Dynamic Power Measurements The Audio Graph PowerCube is a test instrument used to measure the output of an amplifier. It makes measurements in accordance with IHF202 standards. The IHF-202 standard is a Dynamic power measurement. It was developed as a means of measuring power in a manner that best represents the Real World operation of an amplifier.
Information Cubed The data acquired in the testing procedure is then graphed in the form of a 3-dimensional cube, hence the name PowerCube. The Phase Angle is expressed on the horizontal axis, the Output Voltage is presented on the vertical axis and the Impedance is displayed on the Z axis. Output Power, in watts, is listed on the left hand side for each impedance at each phase angle.
W A R R A N T Y I N F O R M AT I O N Rockford Fosgate warrants all electronics to the original consumer/purchaser to be free from defects in materials or workmanship for a period of three (3) years. We will cover parts and labor provided the product was purchased from an Authorized Rockford Fosgate Dealer.
