Treat yourself to an upgrade
When the thrill of owning a new (or new-to-you) car wears off, there's one sure-fire way to bring the excitement back to your drive. Install Infinity's Primus PR5012is 5-1/4" 2-way speakers in your doors and say goodbye to the uninspired vocals, muddy cymbals, and flabby bass of your factory sound. Lifelike vocals, crisp cymbals, and well-defined bass await you. What new playlists will you create to put these awesome speakers to the test?
Edge-driven tweeter design
Infinity employs an edge-driven design in their soft dome tweeters for a smoother, more open response and minimal distortion at high volume. Prepare for a more clearly defined soundstage as the details in your music come alive.
Famous Plus One+ technology
This Primus polypropylene woofer delivers solid, punchy bass, thanks to Infinity's proprietary Plus One+ woofer design. Infinity extends the cone right up to the edge of the basket, giving you lots of surface area — and a bigger cone means more bass when your music needs it.
Make the most of your power
Infinity'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 clearer sound.
Grilles are not included; the factory grilles should be suitable for most applications.

Plus One Woofer Cones: The Plus One speaker cones offer more surface area than other speakers that fit in the same size opening. This is accomplished by using a new basket design and hi-roll surround. The result is greater bass output and an increase in efficiency.
Voice Coil: The Primus Series speakers feature 2.7Ω voice coils to compensate for the high in-line resistance of small gauge factory wiring and extract every watt from the factory receiver, increasing overall system output and efficiency (relative to 4-ohm speakers). The speakers also benefit from increased power when you upgrade the wire and add aftermarket amplifiers capable of powering a lower impedance load.
