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 PR6512is 6-1/2" 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 included.

Features
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.
Impedance: 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.
Mounting: Infinity markets these speakers as 6-1/2"; they will fit in standard 6-1/2" speaker openings (approximately 5" diameter), but they do not use the standard 6-1/2" speaker bolt pattern. In order to install them in standard 6-1/2" applications you must drill new screw holes. If new holes are drilled in the mounting surface of the car, no bracket is needed. If drilling in the car is not an option, the included brackets can be used, which have standard 6-1/2" mounting holes and the Ford non-symmetric four hole pattern. The brackets also offer several other non-standard hole patterns. When using the brackets the depth becomes 1.827" and the mounting height becomes 0.886". The speakers are easily installed in many standard 4-hole 6-3/4" applications with no modification. Enter your vehicle information to confirm fit.

The speakers sound great over the stock speakers that came with the car. The instructions provided by Crutchfield along with the wiring harness and speaker brackets made the installation so easy for me to install it myself.
