Infinity Alpha 603CF Component Speakers
The Infinity Alpha 603CF is a 6.5-inch (165mm) 2-way component car audio speaker system engineered by Harman for powerful, detailed sound. With 90W RMS and 720W peak power handling, it delivers strong performance and is an excellent upgrade over factory vehicle speakers.
Plus One™ Woofer Cones
This patented design maximizes the overall speaker cone area by up to 35% compared to other speakers in its class, resulting in stronger bass and improved midrange performance.
PEI Balanced Dome Tweeters
The system uses 0.75-inch PEI dome tweeters to output crisp, detailed high frequencies with an expanded soundstage.
Compact Mono Crossover Network
Updated iterations feature smaller external crossovers alongside improved heat-dissipation bands, allowing for easier hidden installation behind factory door panels.
Universal Fit Architecture
Vented baskets keep the voice coils cool while the frame is designed to drop cleanly into standard 6.5″ factory locations without heavy vehicle modifications
