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 PR9613is 6-1/2" 3-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 tweeter for a smoother, more open response and minimal distortion at high volume. With the addition of a piezo supertweeter in this 3-way speaker, 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.

Replaced my feeble front door speakers in my '16 Tacoma with Infinity's and am very pleased. Everything went smoothly and now can really enjoy clarity and depth. Rear doors are next!

Pros: Excellent sound and fit.

Cons: None.

Great sounding speakers with easy installation. Highly recommend.

Great sound and great quality

Crutchfield customer from Elbert, CO on 7/24/2019

2000 Honda Accord

Verified customer (What's this?)
Verified employee purchase (What's this?)

Great sound. Had these installed before I installed my sub and amp (forgot to order RCA cables). Good highs and good bass. They thump pretty good for a 6x9. Not the easiest to install but that is how most aftermarket speakers are. None of them fit exactly how the OEM speakers do. There will be some modifying.

Pros: Great sound, high and low

Cons: A little difficult to install for my application

Much Improved Build Quality and Sound Over Stock Speaker

Crutchfield customer from Redlands, CA on 7/11/2019

2017 Toyota Tacoma

Verified customer (What's this?)
Verified employee purchase (What's this?)

One front set of Infinity Primus Pr9813S significantly improved my sound quality over the stock OEM JBL speakers in my 2017 Tacoma Limited double cab truck. Included install instructions were accurate, moreover, easy to follow. Side-by-side speaker comparison revealed a cheap OEM speaker producing inferior sound/music.

Pros: Clean and easy install using provided Tacoma-specific speaker and wire adapters.

Cons:

Look great but not as clear as I expected. But I'm still running stock unit. I'll see how they perform with power added. Well made. Solid.

Pros: Seem durable. Solid, sound good.

Cons: Not as clear as I hoped.

Ram 1500 rear door install

Crutchfield customer from Waynesboro, PA on 6/26/2019

2018 Ram 1500

Verified customer (What's this?)
Verified employee purchase (What's this?)

Not quite as much mid range as I was looking for. Sound is quite good though. I installed these in the rear doors of my Ram pickup to get better balance after having replaced the the dash and front door with Infinity. I went with this 3-way looking for a boost in mids but I did achieve a better sound with the fader now. Having four 6X9's now I don't think I'll need a subwoofer. Rear door install was very easy. 5 stars easily if they had the fat mid-range I was looking for. On sale and the price was nice. Lower impedance means no loss in loudness from my factory head unit too!

Cons:

Product Research

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.
