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.
OPERATING FEATURES
The Series 1 stereo power amplifiers provide state-of-the-art sound in cars, vans, boats, or wherever a high current 12 volt power source is available. Features include:
Discrete Surface Mount Technology – a manufacturing method that allows the packaging of complex circuitry in small areas, reducing noise and crosstalk for lower distortion.
Active Electronic Crossover Module – built into the 2600x and 4600x features 12dB/octave Butterworth filters. The independent crossover modes in these plug-in modules allow for various configuration possibilities.
N-Type V-FET Output Drive Circuitry– delivers music with lower noise and distortion while maintaining a higher slew rate, increased efficiency and higher power output capability than most amplifiers of this class.
High Current/High Voltage Output – delivers the power needed for all listening levels and music frequencies to hear every note.
Pulse Width Modulated (PWM) DC/DC Non-Regulated Power Supply – assures wider dynamic headroom than the more common
regulated power supplies. High or Low Level Adjustable Input Sensitivity – permits maximum
compatibility with source units. This allows adjustment of the input sensitivity level of the power amplifier for RCA (preamp level) or speaker (high level) inputs.
Real Time Power Protection (R.T.P.P.) – allows for the greatest power output under all load conditions. When output reaches an unsafe level it will be reduced, unlike current limiting which often causes premature protection or failure to protect at all.
– 3 –
Gold-Plated Connectors – of high quality to provide lower resistance and better reliability.
Series 1 Housing – The extruded aluminum heatsink design of the Series 1 was designed for high performance cooling.

1. Low Level RCA Input Connectors
The amplifier’s signal input female RCA pin jacks should be connected to the source unit’s signal outputs with high quality RCA cables. The connectors are gold plated to eliminate the possibility of corrosion that can cause signal deterioration.
2. High Level Speaker Input Connectors
These connectors are used to connect to a source unit that does not provide low level RCA outputs. This connector accepts 1/8" spade lugs. Do not attempt to solder wires directly to this connector.
3. LED Power Indicator
The LED illuminates when the unit is in operation.
4. Input Gain Control
This control is factory preset to 500 millivolts to match most radios and is variable from 250 millivolts to one volt.
(More than likely
it will not need adjusting.)
If just a little movement of the volume control from the source unit drives the amplifier into distortion, reduce the input gain control so that the distortion doesn’t start until the source unit volume control is at about 3/4 of its rotation.

5. 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 turn-
on 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.
+R– Connect the Right and Left channel outputs to the
+L–
speakers.
The terminal block connector accepts wire sizes from 10 gauge
to 20 gauge. *
Spade connectors are not needed because of the design of the
connector. The installer should be careful not to allow wires to
fray or touch. The recommended strip length is 1/4" (.635cm).
*Rockford Fosgate’s Perfect Interface line of accessories includes high
quality power and speaker wire, gold-plated RCA interconnecting cables
and other products to complete your installation. Ask your Authorized
Rockford Fosgate Dealer about Perfect Interface.

INSTALLATION CONSIDERATIONS
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. Be sure to carefully read and understand the instructions before attempting to install the amplifier.
2. For safety, disconnect the battery ground cable prior to begin- ning the installation process.
3. For easier assembly, we suggest you run all wires prior to mounting your amplifier in place.
4. Use only quality connectors for making connections. See your Authorized Rockford Fosgate Dealer for Perfect Interface wire enhancements.
5. Think before you drill! Be careful not to cut or drill into gas tanks, fuel lines, brake or hydraulic lines, vacuum lines or electrical wiring when working on any vehicle.
6. Never run wires underneath the vehicle. Running the wires inside the vehicle provides for the best protection.
7. Avoid running wires over or through sharp edges. Use rubber or plastic grommets to protect wires routed through holes in metal.
8. ALWAYS protect the battery and electrical system from damage with proper fusing. Install a fuseholder and fuse within 18” (45.7 cm) of the battery terminal to safeguard from possible damage or injury. This fuse and fuseholder is included with the Series 1 amplifier. (See installation instructions on page 8.)
9. Grounding connections should be as short as possible and always connected to metal that is welded to the main body, or chassis, of the vehicle.
