Infinity Alpha 603M Coaxial Speakers
The Infinity Alpha 603M is a 6.5-inch (165mm) 3-way coaxial car speaker system engineered by Harman to deliver balanced, powerful, and distortion-free sound. Featuring a woofer with dual finely tuned mid/high drivers, it provides clear highs, detailed mids, and strong bass performance. The included protective outer grilles give the speakers a clean, stylish finish while helping protect the drivers during installation.
Plus One™ Polypropylene Cone
This patented Harman architecture extends the cone cone area right up to the edge of the basket. This creates a larger surface area than competing speakers of the same size, resulting in higher sensitivity and better low-frequency bass output.
PEI Balanced Dome Tweeter
Delivers clean, crisp, and well-defined high frequencies while maintaining low distortion at high volumes.
High Factory Compatibility
With a 4-ohm nominal impedance and a 90dB sensitivity rating, these speakers draw power efficiently. They sound vibrant and loud when powered by a low-power factory head unit, though they can also scale well with an aftermarket amplifier.
