Quick Guide
The Infinity Reference 1000SSL and 1200SSL are shallow subwoofer enclosures designed for mobile audio applications. This manual provides essential installation and connection guidelines to ensure optimal performance and safety.
- Professional Installation Recommended: While these instructions cover general installation, professional installation is strongly advised if you lack the necessary tools or experience.
- Safety First: Always wear protective eyewear when using tools and disconnect the vehicle's negative battery terminal before starting.
- Mounting: Choose a location that does not interfere with cargo, fold-down seats, or the trunk lid. Ensure the mounting surface is clear of brake lines, fuel lines, and wiring harnesses before drilling.
Installation Warnings and Tips
Proper installation is critical for both performance and vehicle safety. Follow these guidelines:
- Clearance Check: Verify that screws or wires will not puncture critical vehicle components like brake or fuel lines.
- Electrical Safety: Ensure all electrical connections are secure and properly insulated.
- Preparation: Use a utility knife to remove fabric or vinyl before drilling or cutting to prevent material from snagging in tools.
- Environment: Do not mount speakers in locations where they may get wet.
- Hearing Protection: Playing loud music in an automobile can permanently damage hearing and hinder the ability to hear traffic. Listen at low levels while driving.
Speaker Connections
To connect the subwoofer to your amplifier:
- Polarity: Connect the + and - terminals on the enclosure to the corresponding outputs on your amplifier. Observing proper polarity is essential for sound quality.
- Wire Gauge: Use at least 4mm² (11 AWG) speaker wire for the connections.
- System Setup: The system typically involves a Head Unit connected to an Amplifier, which then drives the Subwoofer. Ensure the 'Remote Turn-On' wire is connected to the amplifier to allow it to power on with the head unit.
Specifications
The Reference series subwoofers have the following technical characteristics:
- Reference 1000SSL: 10" (250mm) Aluminum Driver, 350W RMS / 1050W peak power, 35Hz – 400Hz frequency response, 2 ohms impedance.
- Reference 1200SSL: 12" (300mm) Aluminum Driver, 400W RMS / 1200W peak power, 30Hz – 400Hz frequency response, 2 ohms impedance.
- Enclosure: Both models feature 3/4" (18mm) MDF construction with black carpet covering.
General Care
The loudspeaker may be cleaned with a damp cloth. Do not use any cleaners or solvents. This product is designed for mobile applications and is not intended for connection to the mains.
Practical help
Common problems
Poor bass performance
Ensure the enclosure is securely mounted and the amplifier is correctly connected with proper polarity.
Risk of damage to vehicle components
Check clearances on both sides of the mounting surface to avoid puncturing brake lines, fuel lines, or wiring harnesses.
Hearing damage
Avoid playing loud music for extended periods; listen at low levels while driving.
Before use
- Disconnect the negative (-) lead from the vehicle's battery.
- Wear protective eyewear when using tools.
- Check for hidden obstacles (brake/fuel lines) before drilling.
- Ensure speaker wire is at least 4mm² (11 AWG).
- Verify the mounting location does not interfere with cargo or trunk operation.
Specs in practice
- Power Handling
- RMS power is the continuous power the subwoofer can handle; Peak is the maximum short-term power.
- Frequency Response
- The range of bass frequencies the subwoofer can reproduce (-6dB point).
- Nominal Impedance
- The electrical resistance of the speaker (2 ohms), which must match your amplifier's capabilities.
Images and diagrams
- The wiring diagram shows the connection from the Head Unit to the Amplifier, and then from the Amplifier's 'Speaker Out' to the Subwoofer's + and - terminals.
- Ensure proper polarity (+ to +, - to -) when connecting the subwoofer to the amplifier.
Model compatibility
- Designed for mobile applications only; not intended for connection to mains power.
- Requires an external amplifier for operation.
