## Long description

Infinity Alpha 603M 165mm (6.5") is a 3-way coaxial car speaker designed to upgrade factory sound in a vehicle. The speaker integrates three drivers in a single frame to reproduce a broad frequency range, improving clarity in mid and high frequencies while maintaining the low-frequency presence of a 165 mm woofer. The design is intended for straightforward replacement of standard car speakers and for daily listening scenarios.
Advantages
The 3-way coaxial layout provides separate reproducing elements for lows, mids and highs within one compact unit, reducing the need for additional components. The 165 mm woofer size offers compatibility with common car speaker mounting locations while delivering a familiar low-frequency foundation. Integration of multiple drivers in a single assembly improves imaging and detail compared with typical two-way or single-cone factory speakers. Installation is simplified by the coaxial configuration, allowing direct replacement in many vehicle applications.
Suitable for
Replacing factory or worn car speakers in doors and rear decks
Upgrading everyday in-vehicle audio for clearer mids and highs
Integrating into factory-compatible speaker locations without custom enclosures
Drivers who want a single-speaker solution to cover a wide frequency range
Key specifications
Speaker type: 3-way coaxial
Woofer diameter: 165 mm (6.5")
Configuration: integrated woofer, mid-range and tweeter in one frame
Application: car audio, direct replacement for standard speaker locations
How to use
Prepare the vehicle by disconnecting the battery and removing the door panel or rear deck trim to access the existing speaker. Remove the original speaker and compare the mounting depth and hole pattern to ensure proper fit for the 165 mm (6.5") Infinity Alpha 603M. Connect speaker leads observing polarity, secure the speaker to the mounting surface, and reassemble the trim. After installation, reconnect the battery and perform a brief test at low volume to confirm correct operation and polarity before normal use.
Usage recommendations
The Infinity Alpha 603M is intended for use as a direct replacement or upgrade in standard car speaker locations. For best results, verify mounting depth and speaker cutout dimensions in your vehicle and, if needed, use appropriate adapters or spacers to ensure a secure fit. Avoid applying excessive power beyond typical car head unit or amplifier limits unless the speaker’s power handling has been confirmed by technical documentation.
