4. Setup and Installation
Proper installation is crucial for optimal performance. If you are unsure about any steps, consult a professional installer.
4.1 Mounting the Speakers
- Choose Location: Select a suitable mounting location in your vehicle that provides adequate space and structural integrity. The speakers require a front mount baffle cutout of 6.0" (152mm) and a mounting depth of 2.7" (67.5mm).
- Prepare Opening: Carefully cut the mounting hole using appropriate tools, ensuring the dimensions match the speaker requirements.
- Secure Speakers: Place the speakers into the prepared openings and secure them using appropriate screws or mounting hardware (not included). Ensure a tight fit to prevent vibrations.

4.2 Wiring Connections
The AP-M67AN speakers have a nominal impedance of 4 Ohms. Ensure your amplifier is stable at this impedance. Always observe correct polarity (+ to + and - to -).
- Identify Terminals: Locate the positive (+) and negative (-) terminals on the back of each speaker.
- Connect Speaker Wire: Connect the positive (+) terminal of the speaker to the positive (+) output of your amplifier. Connect the negative (-) terminal of the speaker to the negative (-) output of your amplifier.
- Secure Connections: Ensure all connections are tight and free from frayed wires that could cause short circuits.

5. Operating Instructions
Once installed, follow these guidelines for optimal operation:
- Initial Power-Up: After installation, turn on your audio system at a low volume level. Gradually increase the volume to ensure all connections are correct and the speakers are functioning properly.
- Break-in Period: Allow a break-in period of approximately 10-20 hours of normal listening before operating the speakers at high volumes. This allows the speaker components to loosen and perform optimally.
- Amplifier Settings:
- Gain Setting: Set the amplifier gain correctly to match the output voltage of your head unit. Avoid setting the gain too high, as this can lead to distortion and speaker damage.
- Crossover Settings: For midrange speakers, it is recommended to use a high-pass filter (HPF) to prevent low frequencies from reaching the speakers, which can cause distortion and damage. A typical starting point for the HPF is around 200Hz, but this may vary based on your system and preferences.
- Listening Levels: While these speakers are designed for high power handling (up to 600W MAX, 300W RMS), avoid prolonged listening at distorted levels. Distortion indicates that the amplifier or speakers are being overdriven, which can lead to permanent damage.
6. Maintenance and Care
To ensure the longevity and performance of your Deaf Bonce speakers, follow these simple maintenance tips:
- Cleaning: Use a soft, dry cloth to gently wipe the speaker cones and surrounds. Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the materials.
- Environmental Protection: Protect the speakers from direct sunlight, extreme temperatures, and excessive moisture. While durable, these conditions can degrade speaker components over time.
- Inspect Connections: Periodically check all wiring connections to ensure they remain secure and free from corrosion.
