A modern classic

One thing's for sure — our customers love Infinity's Reference Series speakers. Year after year, car after car, options like these Reference Series REF-9633ix 6"x9" 3-way car speakers remain a popular choice for replacing factory speakers because of their competitive pricing and superb sound.

Enhanced highs

Step up to a 1" edge-driven dome tweeter for smoother highs with minimal breakup. Plus, a supertweeter gives the high frequencies a bolder presence, and push-button tweeter attenuation lets you tweak any "brightness" you might hear.

Plus One+ woofer cone

The Reference Series polypropylene woofer with its durable hi-roll rubber surround ensures you'll enjoy powerful sound every mile you drive. Its oversized cone moves more air than other speakers of similar size, adding plenty of punch to the speaker's impressive performance.

Excellent power-handling

These speakers will really blossom when powered by an external amplifier, but they're also sensitive enough to be a good match for a factory or aftermarket stereo. Plus, Infinity comes up with a safe way to get a little more power out of your system — these 3-ohm speakers combine with the speaker wire in your car so your car stereo sees actual 4-ohm impedance.

Best speaker for your dollar

Crutchfield customer from Knoxville, TN on 4/26/2019

2004 Dodge Ram 2500

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

Phenomenal speakers for the price. I initially had purchased the Kappa series else where but the company had no idea what they were doing and I was unable to fit them. But thankfully crutchfield knows a thing or to about their business and found me a speaker that fit terrifically. I am only running these off a stock head unit without an amp and the sound is tight, crisp, and no distortion when cranked up. Trust me as they are now, there's no trouble getting some serious volume out of these. Would highly recommend them as stock replacements and would imagine they only get better when you put them through a proper head unit and amplifier

Pros: Great fit and the perfect sound you've come to expect from infinity. Easy to run stock or with amp

Cons:

What an upgrade from stock!!

Crutchfield customer from Palm Bay, FL on 3/25/2019

2018 Dodge Charger

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

I replaced the stock door and rear dash speakers with these. What a difference!! Not only are the highs much brighter but the bass is much tighter and not distorted. The stock speakers are cheaply made, just enough to get sound from them. These speakers are much higher quality in materials and workmanship. I am using the stock head unit with no amps at the moment. One of the best upgrades I have done so far.

Pros: Sound quality Materials Ease of install

Cons:

Crutchfield customer from Roseburg, OR on 12/21/2018

2015 Ram 1500

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

Love the sound and the ease of installation. I can really hear a major difference in sound clarity as the volume goes up. The bass has a good thump without distorting the sound. Crutchfield did caution me that the 6x9 was a little too big for the front doors of my RAM but I installed anyways. When my windows are fully down they hit the speaker, I will make adjustments after winter.

Pros: Amazing sound and quality, ease of installation, and price

Cons:

Sounds great, very good quality. But add an amp to get the full capability of the speaker.

Pros: Sound, quality, easy install...

Cons: No real cons, but you really need an amp to get the full benefits of the speak...

Put these in the door of a 15 regular cab silverado. The difference is amazing. I'm just running them off the kenwood double din 45 watt amp and they have really good bass and midrange. Highs are perfect for my setup.

Pros: Easy install, added a lot of bass and highs that are missing. Almost don't need a sub.

Cons: None

Total waste of money bought these to replace the factory paper speakers. These produce less bass and I have to turn the volume up higher to acheive same sound level will be looking into returning these.

Product Research

Features

Plus One+ Woofer Cones: Each speaker uses a cone larger than other speakers of the same size. This is accomplished by using a unique basket design and hi-roll surround. The Plus One+ design offers greater bass output and an increase in efficiency.

Angled Tweeter: The tweeters and super-tweeters are mounted at an angle (fixed), so they can be directed toward the listeners to improve imaging.

Tweeter Level Control: A switch on the front of the tweeter structure allows you to boost the tweeter output to +3dB, useful if the speakers are mounted low in a door where high frequencies are easily absorbed.

High-Output Design: The 3Ω voice coil design compensates for the high in-line resistance of small gauge factory wiring, extracting more power from factory (or aftermarket) receivers.
