3. Safety Information

Always observe the following safety precautions during installation and operation to prevent injury or damage to the equipment:

• Disconnect the vehicle's negative battery terminal before starting any electrical work.
• Ensure proper grounding for all components to prevent electrical shorts and noise.
• Use appropriate wire gauges for power, ground, and speaker connections as specified by the amplifier's requirements.
• Install fuses at the battery and near the amplifier as close as possible to protect against overcurrent.
• Mount the amplifier and enclosure securely to prevent movement during vehicle operation.
• Avoid routing power cables near signal cables to minimize interference.
• Do not expose the equipment to excessive moisture or extreme temperatures.
• Seek professional installation if you are unsure about any steps.

4. Installation and Setup

Proper installation is crucial for the performance and longevity of your subwoofer system. Follow these general guidelines. Specific vehicle wiring diagrams are not included and may vary.

4.1 Mounting the Amplifier and Enclosure

• Choose a secure, well-ventilated location for the amplifier, away from direct sunlight or heat sources.
• Ensure the mounting surface is solid and can support the weight of the amplifier.
• Mount the subwoofer enclosure securely in the trunk or cargo area to prevent it from shifting during driving.

4.2 Wiring Connections

Refer to the diagrams below for amplifier connections. Always ensure the vehicle's battery is disconnected before making any electrical connections.

Figure 4.1: Amplifier rear panel showing input and control connections.

This image details the various input and control terminals on the amplifier, including High Input, RCA Input/Output, Gain, LPF, Sub Sonic, and Remote connections.

Figure 4.2: Amplifier power and speaker output terminals.

This image shows the power input (+12V, REM, GND) and speaker output terminals, along with the fuse slots for the SRX500.1 amplifier.

1. Power Connection (+12V): Run a heavy gauge power cable (e.g., 4 AWG or 8 AWG, depending on total power draw) directly from the vehicle's positive battery terminal to the amplifier's +12V terminal. Install an inline fuse holder within 18 inches (45 cm) of the battery.
2. Ground Connection (GND): Connect a heavy gauge ground cable of the same length as the power cable from the amplifier's GND terminal to a clean, unpainted metal surface on the vehicle chassis. Ensure a solid, low-resistance connection.
3. Remote Turn-On (REM): Connect a smaller gauge wire (e.g., 18 AWG) from the amplifier's REM terminal to the remote turn-on output of your head unit. This signal turns the amplifier on and off with your stereo.
4. Signal Input:
   • RCA Input: If your head unit has RCA pre-outs, connect RCA cables from the head unit's subwoofer output to the amplifier's RCA Input terminals.
   • High-Level Input: If your head unit does not have RCA outputs, use the high-level input. Connect the speaker wires from your head unit's rear speaker outputs to the amplifier's High Input terminal using the provided connector.
5. Speaker Output: The dual 12-inch subwoofers are pre-wired within the enclosure. Connect the speaker wires from the subwoofer enclosure's terminals to the amplifier's Speaker Output terminals. Ensure correct polarity (+ to + and - to -).

5. Operating Instructions

Once installed, you can adjust the amplifier settings to optimize the subwoofer's performance for your vehicle and listening preferences.

5.1 Amplifier Controls (Refer to Figure 4.1)

• GAIN: This control matches the amplifier's input sensitivity to the output level of your head unit. Start with the gain at minimum, then slowly increase it until you hear distortion, then back off slightly. Do not use the gain control as a volume knob.
• LPF (Low Pass Filter): This filter allows only frequencies below the set point to pass through to the subwoofer. Adjust this to blend the subwoofer's output seamlessly with your main speakers. A common starting point is 80-100 Hz.
• SUB SONIC: This filter removes extremely low frequencies that are below the audible range or harmful to the subwoofer. Setting it slightly below your LPF setting (e.g., 20-30 Hz) can improve sound quality and protect the subwoofers.
• REMOTE: This port connects to the included remote level control.

5.2 Remote Level Control

The remote level control allows you to adjust the subwoofer's output level conveniently from the driver's seat without accessing the amplifier directly.

Figure 5.1: Front view of the remote gain control.

This image shows the compact remote gain control unit, featuring a rotary knob for adjusting the subwoofer's output level and an indicator light.

• Connect the remote control to the "REMOTE" port on the amplifier using the provided cable.
• Mount the remote control in an easily accessible location within the vehicle.
• Turn the knob to increase or decrease the subwoofer's volume relative to the main system volume.

6. Maintenance

To ensure the longevity and optimal performance of your Memphis Audio subwoofer system, follow these simple maintenance guidelines:

• Cleaning: Use a soft, dry cloth to wipe down the amplifier and enclosure surfaces. Avoid using harsh chemicals or abrasive cleaners.
• Ventilation: Ensure the amplifier's cooling fins are free from dust and debris to maintain proper airflow and prevent overheating.
• Connections: Periodically check all wiring connections (power, ground, signal, speaker) to ensure they are secure and free from corrosion. Loose connections can lead to poor performance or damage.
• Environment: Protect the system from extreme temperatures, direct sunlight, and moisture.
