1. Pre-Installation Checks
- Vehicle Compatibility: Ensure the speaker sizes (6.5 inch and 6x9 inch) are compatible with your vehicle's speaker openings.
- Power Requirements: Confirm your car audio system (head unit and amplifier, if any) can provide adequate power without exceeding the speakers' RMS power handling.
- Tools Required: Gather necessary tools such as screwdrivers, wire strippers, crimping tool, drill, and safety glasses.
2. Mounting the Speakers
Use the provided cut-out template to mark and cut the speaker openings if new holes are required. Ensure sufficient depth clearance for the speaker magnet.

- Position the speaker in the opening and align the mounting holes.
- Secure the speaker using the provided screws. Do not overtighten, as this can damage the speaker frame.
- Ensure the anti-resonant stamped steel basket and textured ABS gasket provide a tight, secure fit to minimize distortion.
3. Wiring the Speakers
Connect the speaker wires from your car audio system to the speaker terminals. Observe correct polarity (positive to positive, negative to negative) to ensure proper phase and sound quality.
- The speakers feature braided tinsel leads for high conductivity.
- Use appropriate gauge speaker wire for your installation.
- Secure all connections to prevent accidental disconnection or short circuits.
Operating Instructions
Once installed, your Autotek Street Machine speakers are ready for use. These speakers are designed to deliver balanced, full-range audio.
- Initial Playback: Start with a low volume and gradually increase it to ensure all connections are secure and the speakers are functioning correctly.
- Sound Adjustment: Utilize your car audio system's equalizer and balance controls to fine-tune the sound to your preference. The Neo Mylar Soft Dome Tweeters provide crisp highs, while the Alpha-Cellulose Poly Cones produce rich midrange and deep bass.
- Crossover System: The built-in 6dB Butterworth crossover ensures smooth frequency transitions between the speaker components, minimizing distortion.
