Setup and Installation
The Audison APK 570 system is designed for straightforward installation, particularly in car doors that accommodate 5x7 inch elliptical speakers. Due to the compact design of the woofers' baskets and the ultra-compact crossovers, fitting them into OEM locations is simplified.
General Installation Guidelines:
- Safety First: Disconnect the vehicle's battery before beginning any electrical work.
- Mounting Location: Ensure the chosen mounting location in the car door provides sufficient depth and clearance for the woofer. The reduced mounting depth of the APK 570 woofers assists in this.
- Wiring: Connect the woofers and tweeters to the APCX TW 570 crossovers. The woofers feature double Faston connectors for quick and secure wiring.
- Crossover Placement: Place the ultra-compact crossovers in a secure, dry location, ideally close to the speakers to minimize cable length.
- Tweeter Placement: Install the tweeters in a location that allows for optimal sound staging, often in or near the dashboard, A-pillars, or factory tweeter locations.
- Secure Mounting: Use appropriate screws and mounting hardware to firmly secure all components to prevent vibrations and ensure sound quality.
For detailed wiring diagrams and specific vehicle installation instructions, consult a professional car audio installer or refer to the comprehensive installation guide provided with your product packaging.
Operating the System
Once installed, the Audison APK 570 system operates as part of your vehicle's audio setup. The primary operational adjustment available directly on the system components is the tweeter output level attenuation on the APCX TW 570 crossovers.
Tweeter Level Adjustment:
- The APCX TW 570 crossovers include a switch or jumper setting to adjust the tweeter's output level. This allows for fine-tuning the high-frequency response to match your listening preferences and the acoustic environment of your vehicle.
- Refer to the markings on the crossover (e.g., 0 dB, +2 dB) to select the desired attenuation level. Adjustments should be made with the audio system off to prevent damage.
- Experiment with different settings to achieve the most balanced and natural sound reproduction for your specific car interior and speaker placement.
The woofers are designed to be easily driven by various amplifiers, maximizing efficiency without requiring complex filtering due to their mechanical cut-off cone-dust cap system.
Maintenance
Proper maintenance ensures the longevity and optimal performance of your Audison APK 570 system. These components are designed for durability, but regular care is recommended.
- Cleaning: Gently wipe the speaker grilles and surrounds with a soft, dry cloth to remove dust and debris. Avoid using harsh chemicals or abrasive cleaners.
- Environmental Protection: While the woofer cone is water-repellent treated, avoid direct exposure to excessive moisture or extreme temperatures. Ensure the installation environment is as dry and stable as possible.
- Connection Checks: Periodically inspect all wiring connections to ensure they remain secure. Loose connections can lead to degraded sound quality or component damage.
- Professional Inspection: If you notice any significant changes in sound quality or suspect a malfunction, it is advisable to have the system inspected by a qualified car audio technician.
