Setup and Installation

Before You Begin

  • Disconnect the vehicle's negative battery terminal.
  • Plan your wiring path to avoid interference and ensure proper length.
  • Choose a mounting location that provides adequate ventilation and is secure.

Mounting the Subwoofer

Secure the subwoofer using the provided mounting brackets and anti-vibration pads. Ensure the unit is firmly attached to a solid surface to prevent movement. Allow sufficient space around the unit for heat dissipation.

Wiring Connections

Follow these steps for proper wiring. Refer to the 'Controls and Connections' image for visual guidance.

  1. Power Connection (+12V): Connect the +12V terminal on the subwoofer to the vehicle's positive battery terminal. An in-line fuse (not included, but highly recommended) should be installed as close to the battery as possible.
  2. Ground Connection (GND): Connect the GND terminal to a clean, unpainted metal surface on the vehicle chassis. Ensure a solid, low-resistance connection.
  3. Remote Turn-On (REM): Connect the REM terminal to the remote turn-on output of your head unit. This wire signals the subwoofer to turn on and off with your car's audio system. If your head unit lacks a dedicated remote output, you may use an ignition-switched 12V source, or utilize the high-level input's auto-sense feature if available.
  4. Audio Input:
    • RCA Input: If your head unit has RCA pre-outs, connect RCA cables from the head unit to the subwoofer's RCA inputs.
    • High-Level Input: If your head unit does not have RCA outputs, use the provided high-level input adapter to connect directly to your vehicle's speaker wires.

Operating the Subwoofer

Initial Setup and Gain Adjustment

  1. After all connections are made, reconnect the vehicle's negative battery terminal.
  2. Turn on your car audio system.
  3. Set the subwoofer's GAIN control to its minimum position.
  4. Play music with strong bass content at a moderate volume level from your head unit.
  5. Slowly increase the GAIN control on the subwoofer until the desired bass level is achieved without any audible distortion. If distortion occurs, reduce the gain slightly.

Tuning Controls

  • GAIN Control: Adjusts the input sensitivity to match the output voltage of your head unit. Proper gain setting is crucial for optimal performance and to prevent distortion.
  • LOW-PASS CROSSOVER (X-OVER): This control sets the upper frequency limit for the subwoofer, typically adjustable from 50Hz to 150Hz. Frequencies above this setting will be filtered out, ensuring the subwoofer only reproduces low-frequency sounds. Adjust this to blend smoothly with your main speakers.
  • PHASE Switch (0°/180°): This switch adjusts the phase of the subwoofer's output relative to your main speakers. Experiment with both 0° and 180° settings to find the one that provides the most impactful and cohesive bass response in your vehicle.
  • BASS BOOST: Provides an adjustable bass enhancement (+0-12dB) at a specific low frequency. Use this control sparingly to add extra punch to your bass. Excessive use can lead to distortion.
  • VB BASS: Toggles the Virtual Bass Enhancement DSP on or off. Activate it for an enhanced low-frequency perception, making the bass sound fuller.

Wired Remote Control

The included wired remote allows for convenient, on-the-fly adjustment of the bass level from the driver's seat. Connect the remote to the "REMOTE" port on the subwoofer. This control only adjusts the bass level and does not affect other tuning settings.

Maintenance

The RECOIL SS65 is designed for durability and requires minimal maintenance. Follow these guidelines to ensure its longevity:

  • Cleaning: Keep the subwoofer clean and free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using harsh chemicals or abrasive cleaners.
  • Ventilation: Ensure that the area around the subwoofer remains clear to allow for proper airflow and prevent overheating.
  • Environmental Conditions: Avoid exposing the unit to extreme temperatures, direct sunlight for prolonged periods, or excessive moisture.

No Sound Output
  • Incorrect audio input connection
  • Gain control set too low
  • Head unit volume too low or muted
  • Crossover frequency set too high or low
  • Check RCA or high-level input connections.
  • Increase the GAIN control gradually.
  • Ensure the head unit is on and volume is up.
  • Adjust the LOW-PASS CROSSOVER to an appropriate range (e.g., 80-120Hz).
Distorted Sound
  • Gain control set too high
  • Bass Boost set too high
  • Incorrect crossover or phase setting
  • Poor quality audio source
  • Reduce the GAIN control.
  • Lower the BASS BOOST level.
  • Adjust the LOW-PASS CROSSOVER and PHASE switch for optimal sound.
  • Try a different audio source to rule out source issues.
Weak or Lackluster Bass
  • Gain control too low
  • Phase switch incorrect
  • Crossover frequency too low
  • VB Bass off
  • Increase the GAIN control.
  • Toggle the PHASE switch (0°/180°) to find the best setting.
  • Adjust the LOW-PASS CROSSOVER to a slightly higher frequency.
  • Ensure VB Bass is turned ON.
