It fits conveniently under the driver’s or passenger’s seat and includes multiple tuning options to customize your sound. This guide will walk you through the installation process, wiring setup, and control features.

Step 1: What’s Included

Inside the box, you’ll find:

Step 2: Placing the Subwoofer

1. Choose a location under the driver’s seat or passenger’s seat.

3. If mounting is necessary, use the included hardware.

Step 3: Wiring the Subwoofer

Power Connections

• 12V Power Terminal → Connect to the positive terminal of your battery.
• Remote Terminal → Connect to your vehicle’s ignition, accessory wire, or head unit’s remote output.

Phase Switch

• Flips the subwoofer’s phase to 180°.
• Adjust based on your vehicle’s acoustics to ensure proper bass alignment.

Crossover Controls

• Low-Pass Filter:
  • Determines the highest frequency the subwoofer plays.
  • Example: 100Hz means the subwoofer plays everything below 100Hz.
• Subsonic High-Pass Filter:
  • Blocks inaudible ultra-low frequencies.

• Mount it within reach of the driver.
• Allows quick volume adjustments without accessing the subwoofer directly.

Step 7: Final Setup
