## Summary description

Infinity Alpha 603 is a coaxial car speaker with a 165 mm (6-1/2") diameter designed for vehicle audio systems. It combines a mid-bass driver and integrated tweeter to reproduce a broad frequency range suitable for everyday listening.

## Long description

Infinity Alpha 603 165 mm (6-1/2") coaxial car speaker is designed to replace or upgrade factory door or parcel shelf speakers in passenger vehicles. The speaker integrates a mid-bass driver and a mounted tweeter to deliver a broader frequency range than many original-equipment units, improving clarity and stage perception for everyday in-car music playback.
Advantages
The coaxial design combines a mid-bass driver and integrated tweeter in a single compact frame, allowing clear midrange and articulated high frequencies from one unit. The 165 mm (6-1/2") diameter matches common aftermarket and factory mounting sizes, simplifying installation. As an Infinity Alpha series component, the speaker emphasizes balance between sound quality and compatibility with standard car audio systems.
Suitable for
 Replacing worn or damaged factory door or rear deck speakers
 Upgrade of stock car audio for clearer vocals and improved treble
 Use in compact systems where space is limited but a wider frequency response is desired
Key specifications
 Type: Coaxial car speaker with integrated tweeter
 Nominal diameter: 165 mm (6-1/2")
 Driver configuration: Mid-bass driver plus mounted tweeter
 Application: Designed for vehicle audio systems (door or parcel shelf installation)
 Compatibility: Replacement/upgrade for common 165 mm factory speaker locations
How to use
Before installation, disconnect the vehicle battery and remove the existing speaker while noting wiring polarity. Mount the Infinity Alpha 603 into the speaker opening that accepts 165 mm (6-1/2") speakers using the factory or compatible aftermarket grille and screws. Reconnect wiring observing correct polarity to maintain coherent phase and sound staging. Once mechanically secured and wired, test playback at low volume to confirm correct operation and adjust balance or equalization from the head unit or amplifier as necessary.
Usage recommendations
For best results, pair the Infinity Alpha 603 with a cleanly powered factory or aftermarket head unit and ensure proper speaker wiring and mounting. Avoid applying excessive equalization or high-power amplification without verifying the speaker's power handling and an appropriate high-pass filtering if used with powerful amplifiers to prevent distortion.
