INTRODUCTION Dear Customer, Congratulations on your purchase of the world's finest brand of car audio amplifiers. At Rockford Fosgate we are fanatics about musical reproduction at its best, and we are pleased you chose our product. Through years of engineering expertise, hand craftsmanship and critical testing procedures, we have created a wide range of products that reproduce music with all the clarity and richness you deserve.
GETTING STARTED Welcome to Rockford Fosgate! This manual is designed to provide information for the owner, salesperson and installer. For those of you who want quick information on how to install this product, please turn to the Installation Section of this manual. Other information can be located by using the Table of Contents. We, at Rockford Fosgate, have worked very hard to make sure all the information in this manual is current.
DESIGN FEATURES 1 Power and Speaker Connection 4 5 2 6 9 3 7 10 4 7 11 6 8 10 1. LED Power Indicator – The LED illuminates when the unit is turned on. 2. REM Terminal – This spade terminal is used to remotely turn-on and turn-off the amplifier when +12V DC is applied. 3. Power Terminals – The power and ground connectors on the amplifier are gold-plated and will accommodate up to 4 AWG wire maximizing the input current capability of the amplifier. 4.
INSTALLATION INSTALLATION CONSIDERATIONS The following is a list of tools needed for installation: Volt/Ohm Meter Wire strippers Wire crimpers Wire cutters #2 Phillips screwdriver Battery post wrench Hand held drill w/assorted bits 1/8" diameter heatshrink tubing Assorted connectors Adequate Length—Red Power Wire Adequate Length—Remote Turn-on Wire Adequate Length—Black Grounding Wire This section focuses on some of the vehicle considerations for installing your new Amplifier.
INSTALLATION Trunk Mounting Mounting the amplifier vertically will provide the best cooling of the amplifier. Mounting the amplifier on the floor of the trunk will work but provides less cooling capability than vertical mounting. Mounting the amplifier upside down to the rear deck of the trunk will not provide proper cooling and will severely affect the performance of the amplifier and is strongly not recommended.
INSTALLATION 5. Prepare the BLACK wire (Ground cable) for attachment to the amplifier by stripping 1/2" of insulation from the end of the wire. Insert the bared wire into the GND terminal and tighten the set screw to secure the cable in place. Prepare the chassis ground by scraping any paint from the metal surface and thoroughly clean the area of all dirt and grease. Strip the other end of the wire and attach a ring connector. Fasten the cable to the chassis using a non-anodized screw and a star washer. 6.
INSTALLATION 2-Channel Wiring • RCA Inputs connect to Front • Signal Imput Switch set to 2 • Gain - front and rear set equally • Crossover - front and rear set identically (example; switch to LP and frequency at 60Hz) Bridged Left 3-Channel Wiring 4-Channel 2-Channel • RCA Inputs connect to Front or Front and Rear • Signal Imput Switch set to 2 or 4 NOTE: Reverse polarity on subwoofer if front channel is set to HP (High Pass) and rear channel is set to LP (Low Pass) Bridged 4-Channel Wiring
INSTALLATION USING PASSIVE CROSSOVERS A passive crossover is a circuit that uses capacitors and/or coils and is placed on speaker leads between the amplifier and speaker. The crossover delegates a specific range of frequencies to the speaker for optimum driver performance. A crossover network can perform one of three functions: High-Pass (capacitors), Low-Pass (inductors or coils) and Bandpass (combination of capacitor and coil). The most commonly used passive crossover networks are 6dB/octave systems.
OPERATION ADJUSTING GAIN Do the following individually for each channel. To adjust the gain setting, turn the amplifier gains all the way down. Turn the source unit volume up until distortion is audible and then turn it down a bit until the distortion is inaudible. This will be about two thirds all the way up on most source units. Next, turn the amplifier gain setting until once again distortion is audible and then back it down until the distortion is inaudible.
TROUBLESHOOTING NOTE: If you are having problems after installation follow the Troubleshooting procedures below. Procedure 1: Check Amplifier for proper connections. Verify that POWER light is on. If POWER light is on skip to Step 2, if not continue. 1. Check in-line fuse on battery positive cable. Replace if necessary. 2. Verify that Ground connection is connected to clean metal of the vehicle’s chassis. Repair/replace if necessary. 3. Verify there is 10.5 - 15.
