4. Setup and Installation
The CH6CK system is designed for component installation, allowing for flexible placement of woofers and tweeters to optimize sound staging.
4.1 Woofer Installation
The 6.5-inch woofers are typically installed in factory speaker locations in car doors or rear decks. Ensure the mounting depth and diameter are compatible with your vehicle's openings.

- Cone Material: The woofer cone is made from polyurethane, offering durability and sound reproduction.
- Surround Material: The rubber surround provides flexibility and resilience, allowing for consistent cone movement.
- Voice Coil: Designed to withstand high temperatures, maintaining strength for extended play.
4.2 Tweeter Installation
The piezoelectric tweeters can be flush-mounted or surface-mounted, depending on your vehicle's interior and desired sound dispersion. Place them in locations that provide clear, unobstructed sound to the listening area, such as dashboard corners or A-pillars.

4.3 Crossover Network Connection
The passive crossovers are crucial for directing the correct frequency ranges to the woofers and tweeters. Connect the output from your amplifier or head unit to the input terminals of the crossover. Then, connect the woofer and tweeter outputs from the crossover to their respective speakers.

The crossovers ensure that the woofers handle low and mid-range frequencies, while the tweeters handle high frequencies, preventing damage and optimizing sound clarity.
5. Operating Instructions
Once installed, your CH6CK speaker system will operate in conjunction with your car's head unit or external amplifier. No direct user controls are present on the speakers themselves.
- Audio Source: Play audio through your car's head unit (radio, CD player, media player).
- Volume Control: Adjust the volume using your head unit's controls.
- Tone Adjustments: Use the equalizer or tone controls on your head unit or amplifier to fine-tune the bass, midrange, and treble to your preference.
- Power Source: The speakers are powered by your car's 12V electrical system, typically through the head unit or an external amplifier.
6. Maintenance
The BOSS Audio Systems CH6CK speakers require minimal maintenance.
- Cleaning: Use a soft, dry cloth to gently wipe dust from the speaker cones and grilles. Avoid using harsh chemicals or abrasive cleaners.
- Inspection: Periodically check speaker connections for tightness and ensure no wires are frayed or exposed.
- Environmental Protection: While durable, avoid exposing speakers to excessive moisture or extreme temperatures. These speakers are not waterproof.
7. Troubleshooting
If you encounter issues with your speaker system, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound from speakers | Loose wiring connection Incorrect wiring Amplifier/head unit issue | Check all speaker and crossover connections. Verify wiring polarity and connections to head unit/amplifier. Ensure head unit/amplifier is powered on and functioning. |
| Distorted or unclear sound | Overpowering speakers Incorrect gain settings on amplifier Damaged speaker cone/surround | Reduce volume. Ensure amplifier output matches speaker ratings. Adjust amplifier gain settings according to manufacturer recommendations. Inspect speaker for physical damage. |
| One speaker not working | Loose connection to that speaker Faulty speaker or crossover | Check connections for the specific speaker and its crossover. Swap speaker/crossover with a working one to isolate the fault. |
| Tweeters are too loud/harsh | High frequency emphasis on head unit/amp | Adjust the treble or high-frequency equalizer settings on your head unit or amplifier. |
