6.3. Connecting to Vehicle Audio System
- Run Speaker Wire: Route appropriate gauge speaker wire from your car stereo's amplifier or head unit to the location of the speaker boxes. Ensure wires are not pinched or exposed to sharp edges.
- Connect to Boxes: Connect the speaker wires from your car audio system to the terminals on the back of the speaker boxes. Match positive (+) to positive (red) and negative (-) to negative (black).
- Secure Boxes: Once wired, securely mount the speaker boxes in their desired location using appropriate fasteners. This prevents movement and potential damage.
6.4. Final Steps
- Reconnect Battery: Reconnect the negative terminal of your vehicle's battery.
- Test System: Turn on your car audio system and test the speakers at a low volume. Gradually increase the volume to ensure proper operation and sound quality.
7. Operating Instructions
The Audiobank AB790 speakers are passive components and operate in conjunction with your vehicle's car stereo or amplifier. There are no direct controls on the speakers themselves.
- Volume Control: Adjust the volume using your car stereo's controls.
- Audio Settings: Utilize your car stereo's equalizer, balance, and fader controls to optimize sound output to your preference.
- Break-in Period: Allow a short break-in period (typically 10-20 hours of normal listening) for the speaker components to loosen up and achieve optimal performance. Avoid excessively high volumes during this period.
8. Maintenance
Proper maintenance ensures the longevity and performance of your speakers:
- Cleaning: Use a soft, dry cloth to wipe down the speaker boxes and grills. Avoid abrasive cleaners or solvents.
- Environmental Protection: While the speaker boxes are constructed from MDF, they are not waterproof. Avoid exposing them to excessive moisture or direct sunlight for prolonged periods.
- Connection Checks: Periodically check all wiring connections to ensure they remain secure and free from corrosion.
- Grill Care: The speaker grills protect the cones. Handle them carefully. If they become loose, re-secure them gently.
