Setup and Installation
Proper installation is crucial for optimal sound performance and system longevity. Follow these general guidelines:
1. MB Quart DS2-216 6.5-inch Component Speakers
The DS2-216 system consists of woofers, tweeters, and external passive crossovers. These components are designed to be installed separately for optimized sound staging.
- Woofer Installation: Mount the 6.5-inch woofers in factory speaker locations or custom enclosures. Ensure a secure fit to prevent vibrations.
- Tweeter Installation: Install the aluminum inverted dome tweeters in locations that provide clear sound dispersion, such as dash corners or A-pillars. Various mounting options (flush, surface) may be available.
- Crossover Installation: The external passive crossovers manage frequency distribution between the woofer and tweeter. Mount them in a dry, accessible location, away from heat sources and moisture. Connect the amplifier output to the crossover's input, then connect the woofer and tweeter to their respective outputs on the crossover.

2. MB Quart DK2-108 3.5-inch Coaxial Speakers
The DK2-108 coaxial speakers integrate the tweeter directly into the woofer assembly, simplifying installation.
- Installation: Mount the 3.5-inch coaxial speakers in factory locations designed for this size. Ensure the mounting surface is flat and secure.
- Wiring: Connect the speaker wires directly to the coaxial speaker terminals. The DK2-108 features a 6dB internal crossover, eliminating the need for an external unit.

Wiring Considerations
Always use appropriate gauge speaker wire for your installation. Ensure correct polarity (+ to + and - to -) for all connections. Incorrect wiring can lead to poor sound quality or damage to the speakers and amplifier. Refer to your vehicle's wiring diagram and your amplifier's manual for specific connection details.
Operating Instructions
Once installed, connect your speaker system to a compatible car audio head unit or amplifier. Follow these steps for initial operation:
- Power On: Turn on your car's audio system.
- Volume Control: Start with the volume at a low level.
- Audio Settings: Adjust the bass, treble, balance, and fader settings on your head unit or amplifier to achieve desired sound. Avoid excessive bass or treble boost, which can distort sound or damage speakers.
- Break-in Period: Allow a break-in period of several hours of normal listening before operating the speakers at high volumes. This allows the speaker components to loosen and perform optimally.
Maintenance
- Cleaning: Use a soft, dry cloth to gently wipe dust from speaker grilles and cones. Avoid using harsh chemicals or abrasive cleaners.
- Inspection: Periodically check speaker mounts and wiring connections to ensure they remain secure.
- Environmental Factors: Protect speakers from extreme temperatures, direct sunlight, and excessive moisture.
