1. Power Connection (+12V): Connect a fused power cable (minimum 8 AWG) directly from the positive terminal of the vehicle's battery to the +12V terminal on the amplifier. Install a fuse holder within 18 inches of the battery.
2. Ground Connection (GND): Connect a ground cable (minimum 8 AWG) from the GND terminal on the amplifier to a clean, unpainted metal surface on the vehicle's chassis. Ensure a solid, low-resistance connection.
3. Remote Turn-On (REM): Connect a remote turn-on wire from your head unit's remote output to the REM terminal on the amplifier. This wire signals the amplifier to turn on and off with your head unit.
4. Input Signal: Connect your head unit's RCA outputs to the amplifier's RCA inputs (CH1, CH2, CH3, CH4). If your head unit does not have RCA outputs, use the high-level inputs.
5. Speaker Connections: Connect your speakers to the corresponding speaker output terminals on the amplifier. Pay close attention to polarity (+ and -). For bridged operation, refer to the diagram on the amplifier or in the specifications section.

6. Operating Instructions

Once installed, you can configure your amplifier for optimal sound.

6.1 Gain Adjustment

The gain control matches the amplifier's input sensitivity to the output level of your head unit. Start with the gain set to minimum (fully counter-clockwise). Play a familiar track at about 75% of your head unit's maximum volume. Slowly increase the amplifier's gain until you hear distortion, then back off slightly until the sound is clear.

6.2 Crossover Settings

The EVOX2 800.4-4 features adjustable high-pass (HP) and low-pass (LP) filters for each pair of channels. These filters allow you to direct specific frequency ranges to your speakers.

• HP (High-Pass Filter): Allows frequencies above the set point to pass through. Useful for full-range speakers or tweeters to prevent low-frequency distortion.
• LP (Low-Pass Filter): Allows frequencies below the set point to pass through. Useful for subwoofers to prevent high-frequency distortion.
• FULL: Disables the crossover, allowing the full frequency range to pass.

Adjust these settings based on the type of speakers connected to each channel for optimal sound quality and speaker protection.

7. Maintenance

The SounDigital EVOX2 amplifier requires minimal maintenance. Follow these guidelines to ensure its longevity:

• Keep the amplifier clean and free of dust and debris. Use a soft, dry cloth for cleaning.
• Ensure all connections remain secure. Periodically check wiring for any signs of wear or corrosion.
• Do not block the cooling fins or vents, as this can lead to overheating.
