nfinity's special "true 4-ohm architecture" uses a low-impedance voice coil to safely draw extra power out of your factory radio, aftermarket stereo, or an external amplifier, so you'll get a stronger and clearer sound.
Infinity knows what music should sound like in the car, and their Primus PR503CF 5-1/4" component speaker system fits more vehicles than ever. Plus, new technology, like Infinity's cooling vented basket frame, ensures maximum output with less wear and tear over the life of these speakers. Ditch the uninspired vocals, muddy cymbals, and flabby bass of your factory sound and experience what Infinity quality is all about. Smooth vocals, crisp cymbals, and rich bass await you.
Infinity employs an edge-driven design for an open sound and minimal distortion at high volume. Prepare for a more clearly defined soundstage as the natural details in your music come alive. The included external crossovers are tuned to Infinity's exceptional standards so that you're treated to this system's best possible sound.
The Primus polypropylene woofer employs Infinity's proprietary Plus One woofer design for solid, punchy bass. Infinity extends the cone right up to the edge of the basket, for more surface area — and a bigger cone means more bass when your music needs it.
