## Long description

The Infinity Alpha 603F 165 mm (6.5") coaxial speaker is a two-way car audio unit designed to replace factory speakers or fit into custom door panels. Featuring a mid/bass driver with an integrated tweeter, this model delivers clearer vocal reproduction and balanced midrange response. With a nominal power rating of 120 W, the speaker is built for reliable daily use and improved sonic detail compared with typical stock speakers.
Advantages

The 165 mm woofer provides solid midrange and bass foundation while the integrated tweeter enhances high-frequency clarity. The speaker’s power handling and construction are tuned for consistent performance in automotive environments and for longer-term reliability in everyday driving conditions.

Key specifications
Driver diameter: 165 mm (6.5")
Configuration: two-way coaxial (mid/bass driver with integrated tweeter)
Nominal power handling: 120 W
Intended application: automotive car audio
Mounting style: flush-mount coaxial speaker suitable for standard 6.5" cutouts
How to use
Install the Infinity Alpha 603F by removing the factory speaker and matching the speaker’s mounting holes and connector polarity. Secure the speaker into the existing 6.5" cutout or an appropriate adapter bracket, ensuring a stable mechanical fit and good sealing against the door or panel to reduce vibration and air leaks. Connect the speaker wires observing correct polarity and test audio playback at low volume before finalizing the installation. If necessary, use foam gasket or sealing tape to improve mounting stability and prevent rattles.
Usage recommendations
For best results, pair the speakers with a head unit or amplifier that provides clean power within the speaker’s rated limits and avoid excessive clipping. Use proper mounting adapters when the factory cutout differs from the 165 mm size and inspect wiring and connectors for secure, corrosion-free contact. Break in the speakers with varied, moderate-volume playback over the first 20–40 hours to achieve more balanced tonal response.
