Infinity INF RA 6006 6-Channel Power Amplifier User Manual

Introduction

This manual provides detailed instructions for the installation, operation, and maintenance of your Infinity INF RA 6006 6-Channel Power Amplifier. Please read this manual thoroughly before attempting to install or operate your amplifier to ensure proper use and to prevent damage to the unit or your vehicle's audio system. Keep this manual for future reference.

Safety Information

Always observe the following safety precautions:

Disconnect the vehicle's negative battery terminal before starting any installation.
Ensure all wiring is properly routed and secured to prevent pinching or damage.
Use appropriate gauge wiring for power and ground connections as specified in the installation section.
Avoid installing the amplifier in locations exposed to direct sunlight, excessive heat, moisture, or dust.
Do not operate the amplifier if it is damaged or malfunctioning. Refer to the troubleshooting section or contact qualified service personnel.
Always use fuses of the specified rating. Never replace a fuse with one of a higher rating.

Setup and Installation

Proper installation is crucial for optimal performance and longevity of your amplifier. If you are unsure about any part of the installation process, consult a professional installer.

1. Unpacking

Carefully remove the amplifier and all accessories from the packaging. Inspect for any signs of damage. If damage is found, contact your dealer immediately.

2. Mounting Location

Choose a mounting location that is dry, well-ventilated, and away from direct heat sources. Ensure there is sufficient space around the amplifier for proper air circulation. Common locations include under a seat, in the trunk, or behind a panel. Secure the amplifier firmly to a solid surface using the provided mounting hardware.

3. Wiring Connections

All wiring should be performed with the vehicle's battery disconnected.

Power (B+) Wire: Connect a heavy-gauge power wire (e.g., 4-gauge or 8-gauge depending on system power) directly from the positive terminal of the vehicle's battery to the B+ terminal on the amplifier. Install an in-line fuse holder with an appropriate fuse (not supplied) within 18 inches (45 cm) of the battery.
Ground (GND) Wire: Connect a heavy-gauge ground wire of the same size as the power wire from the GND terminal on the amplifier to a clean, unpainted metal surface of the vehicle's chassis. Ensure a good electrical connection.
Remote (REM) Turn-On Wire: Connect a smaller gauge wire (e.g., 18-gauge) from the REM terminal on the amplifier to the remote turn-on output of your head unit. This wire turns the amplifier on and off with your head unit.
RCA Input Cables: Connect the RCA output cables from your head unit to the corresponding RCA input jacks on the amplifier. Ensure correct channel matching (Front, Rear, Subwoofer).
Speaker Wires: Connect the speaker wires from your speakers to the appropriate speaker output terminals on the amplifier. Pay close attention to polarity (+ and -) for each speaker. The INF RA 6006 supports 6 channels, allowing for various configurations (e.g., 3-way stereo, 2-way stereo + subwoofer, or bridged configurations). Refer to your speaker impedance and amplifier specifications for safe operation.

4. Initial Settings

Before reconnecting the battery, ensure all connections are secure. After reconnecting the battery:

Gain Control: Start with the gain controls set to minimum. Turn on your head unit and slowly increase the volume until distortion is audible. Then, slowly increase the amplifier's gain control until the desired volume is reached without distortion.
Crossover Settings: The amplifier features built-in crossovers. Adjust the High-Pass Filter (HPF) for full-range speakers and the Low-Pass Filter (LPF) for subwoofers to optimize sound quality and protect your speakers. Refer to your speaker manufacturer's recommendations for crossover frequencies.
Bass Boost: Use the bass boost feature sparingly and with caution to avoid speaker damage. Start with it off and only apply a small amount if desired.

Operating the Amplifier

Once installed and initially configured, the amplifier operates automatically with your head unit. The primary adjustments will be made through your head unit's volume and tone controls.

Power On/Off: The amplifier will turn on when your head unit is powered on (via the remote turn-on wire) and turn off when the head unit is off.
Volume Control: Adjust the overall system volume using your head unit. The amplifier's gain control should be set once during initial setup and generally not adjusted during normal operation.
Sound Customization: Fine-tune your audio experience using the crossover settings and bass boost on the amplifier, or through your head unit's equalizer and sound processing features.

Maintenance

The Infinity INF RA 6006 amplifier is designed for reliable operation with minimal maintenance.

Cleaning: Periodically wipe the exterior of the amplifier with a soft, dry cloth to remove dust. Do not use harsh chemicals or abrasive cleaners.
Inspection: Annually inspect all wiring connections for tightness and corrosion. Ensure the amplifier's mounting remains secure. Check for any obstructions to airflow around the heat sink fins.
Fuse Replacement: If the amplifier stops working, check the in-line fuse near the battery and the fuses on the amplifier itself (if applicable). Always replace a blown fuse with one of the exact same type and rating.

Troubleshooting

If you experience issues with your amplifier, refer to the following common problems and solutions before contacting service.

Problem	Possible Cause	Solution
No Power / Amplifier does not turn on	Blown fuse (in-line or on amplifier) Loose power or ground connection Remote turn-on wire not connected or faulty Vehicle battery discharged	Check and replace fuses with correct rating. Verify all power and ground connections are secure. Ensure remote wire is connected to head unit's remote output and head unit is on. Charge or replace vehicle battery.
No Sound Output	RCA input cables disconnected or faulty Speaker wires disconnected or shorted Head unit volume too low or muted Amplifier gain set too low	Check RCA connections at both amplifier and head unit. Inspect speaker wiring for proper connection and shorts. Increase head unit volume and check mute settings. Adjust amplifier gain control.
Distorted Sound	Amplifier gain set too high Head unit volume too high Improper crossover settings Speaker impedance mismatch	Reduce amplifier gain. Lower head unit volume. Adjust HPF/LPF settings. Verify speaker impedance is compatible with amplifier.
Amplifier Overheating	Insufficient ventilation Speaker impedance too low Prolonged high-volume operation	Ensure adequate airflow around the amplifier. Check speaker impedance. Reduce volume or allow amplifier to cool down.
