3.2 Wiring Connections

The SU6901 supports both RCA (low-level) and high-level (speaker) inputs, allowing compatibility with both aftermarket and factory stereo systems.

1. Power Connection: Connect the main power wire (+12V) to the vehicle's battery (positive terminal) via an appropriate fuse (15A/20A recommended). Connect the ground wire (GND) to a clean, unpainted metal surface on the vehicle chassis.
2. Remote Turn-On (REM): Connect the remote turn-on wire to the remote output of your head unit. If your head unit does not have a remote output, the subwoofer features an "Auto Power On" function that detects audio signal.
3. Audio Input:
   • RCA Input: Connect RCA cables from your head unit's subwoofer or pre-amp outputs to the "LOW LEVEL INPUT" jacks on the subwoofer.
   • High-Level Input: If your head unit does not have RCA outputs, use the provided high-level input harness. Connect the speaker wires from your head unit's speaker outputs to the corresponding inputs on the high-level harness, then plug the harness into the "HIGH LEVEL INPUT" port on the subwoofer.
4. Remote Control: Plug the wired remote control into the "REMOTE CONTROL" port for convenient bass level adjustment.

4. Operating Instructions

Once installed, you can adjust the subwoofer's settings to optimize its performance with your vehicle's audio system.

4.1 Control Panel Adjustments

The control panel on the subwoofer allows for fine-tuning of the audio output:

• Input Gain: Adjusts the input sensitivity to match the output level of your head unit. Start low and gradually increase until desired volume is achieved without distortion.
• Low Pass Filter (LPF): This variable filter allows you to set the upper frequency limit for the subwoofer, typically between 50Hz and 150Hz. This ensures the subwoofer only reproduces bass frequencies, preventing it from playing mid-range sounds.
• Bass Boost: Provides an adjustable bass enhancement, typically from 0 to +18dB, to increase the intensity of low frequencies. Use sparingly to avoid distortion.
• Phase Control: A switch (0°/180°) to adjust the phase of the subwoofer's output relative to the main speakers. Adjust this to achieve the most cohesive bass response.
• Auto Power On: If using high-level inputs and no remote turn-on wire, set this switch to "ON" for automatic power detection.

4.2 Remote Control

The included wired remote control allows for convenient adjustment of the bass level from the driver's seat without needing to access the subwoofer directly.
