The Infinity Alpha 603 is a high-quality 2-way coaxial car speaker system specifically designed for audio performance in vehicles. With a diameter of 16 cm (6.5 inches), this speaker delivers balanced sound reproduction across a wide frequency range from 55 Hz to 20 kHz. The combination of a powerful 16 cm woofer and a precisely tuned tweeter creates a coherent soundstage that reproduces both mids and highs clearly and distinctly. With a peak power of 480 watts and a nominal power of 60 watts, the Alpha 603 is capable of delivering impressive sound quality even at higher volumes. The robust construction and the use of durable materials ensure long-term reliability, while the easy installation with the included mounting hardware allows for straightforward integration into many vehicle models.
