1. Installing Speakers into Mounting Adapters
The provided Vixen Go VGB6703 speaker mounting adapters are designed to adapt the 6.75-inch KICKER speakers to your vehicle's factory speaker openings. The speakers are installed from behind the adapter.
- Align the KICKER speaker with the mounting adapter, ensuring the speaker is placed behind the adapter.
- Line up the screw holes on the speaker with the corresponding holes on the adapter.
- Secure the speaker to the adapter using the screws provided with your KICKER speakers. These screws are typically suitable for this connection. If needed, smaller or larger screws, or washers, can be used for a tighter fit.

Operation
Once properly installed, your KICKER DS Series speakers will operate as part of your vehicle's audio system. No specific user interaction is required beyond adjusting your car's head unit settings (volume, balance, fader, equalizer) to your preference. These speakers are designed to deliver a full-range sound experience with clear bass and high sensitivity.
- Volume Control: Adjust the volume through your car's head unit.
- Audio Settings: Utilize your head unit's equalizer and sound processing features to fine-tune the audio output to your listening environment.
- Break-in Period: Allow a short break-in period (typically 10-20 hours of normal use) for the speaker components to fully settle and achieve optimal sound quality.
Maintenance
KICKER DS Series speakers are designed for durability and require minimal maintenance. Follow these guidelines to ensure longevity:
- Cleaning: Gently wipe the speaker grilles and surrounds with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners.
- Inspection: Periodically check speaker connections for tightness and ensure no wires are frayed or exposed.
- Environmental Factors: While designed for automotive use, avoid exposing speakers to excessive moisture or extreme temperatures beyond normal vehicle operating conditions.
Troubleshooting
If you experience issues with your KICKER speakers, refer to the following common troubleshooting steps:
- No Sound:
- Check all wiring connections at the speaker and the vehicle's factory harness. Ensure they are secure and correctly polarized (positive to positive, negative to negative).
- Verify that your car's head unit is powered on and set to an appropriate audio source.
- Check the fader and balance settings on your head unit.
- Distorted Sound:
- Reduce the volume level on your head unit. Distortion at high volumes may indicate the amplifier (if present) or head unit is overdriven.
- Check for loose connections or damaged speaker wires.
- Ensure the speakers are securely mounted and not vibrating against the door panel.
- One Speaker Not Working:
- Swap the non-working speaker with a known working one (if possible) to determine if the issue is with the speaker or the wiring/head unit channel.
- Inspect the specific wiring harness for that speaker for any damage or loose connections.
If these steps do not resolve the issue, contact KICKER customer support or a certified car audio technician.
