Designed for more clarity

Do you want to hear the details you've been missing in your car's sound system? You'll enjoy exceptional clarity from Infinity's Reference X Series REF-3002cfx 3-1/2" speakers. Infinity uses PEI balanced dome tweeters to bring out all the details in your music without sounding harsh.

Larger woofer for fuller sound

The REF-3002cfx features tough polypropylene woofers and durable hi-roll rubber surrounds that deliver strong performance. Each Plus One+ woofer sports a significantly larger cone than speakers of similar size, adding plenty of punch to the speaker's smooth and accurate highs.

Great for any power supply

You can power these speakers with up to 25 watts of RMS power — they'll work great with an external amplifier, but they're also 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 vehicle so your car stereo sees actual 4-ohm impedance. Grilles are not included — factory grilles are appropriate for most installations.

Product Highlights:

  • 3-1/2" 2-way speakers (pair)
  • Plus One+ polypropylene woofer cone with hi-roll rubber surround
  • PEI balanced dome tweeter
  • True Four Ohm Impedance technology: speaker's 3-ohm impedance combines with speaker wire impedance for a 4-ohm load
  • compatible with virtually all factory or aftermarket car stereos
  • power range: 5-25 watts RMS (75 watts peak power)
  • frequency response: 85-21,000 Hz
  • sensitivity: 91 dB
  • top-mount depth: 1-7/16"
  • warranty: 1 year
  • Our 60-day money-back guarantee

Product Research


Plus One+ Woofer Cones: Each speaker uses a cone significantly 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.

Hi-roll Rubber Surrounds: The hi-roll rubber surrounds allow the woofers a greater range of movement, resulting in longer X-max and more bass output.

Tweeter: Each speaker has a balanced dome tweeter. A semi-dome tweeter has a dome placed inside a cone. Balanced dome tweeters are semi-dome tweeters with equal reproduction area given the cone and dome portions of the tweeter.

True Four Ohm Impedance Technology: The speaker's 3-ohm impedance combined with the impedance of your speaker wire provides a true 4-ohm load to your connected head unit or amplifier.

Power Handling: Although Infinity rates the 3002cfx speakers at 25 watts RMS (continuous average), they also recommend amplifiers with a power rating from 5 to 50 watts RMS.

Too Bright

Written By Randy, Washington on Monday, December 15, 2014

I put these in my 2014 Dodge Dart to replace the factory speakers. First off they sound way too bright, the treble is way too much even with the treble control turned all the way down on the head unit. In my opinion the frequency cut off for the tweeter needs to be at a higher point, not sure where they are cutting it off with the factory cap. The Vocals seem harsh too, not very lifelike. I returned these speakers and got the JBL gto329's and the vocals sound much better but even on these speakers the treble is too much. I am going to probably going to go back to the factory speakers which sound great, just wanted more treble, and probably add on some separate tweets with a crossover and I might have a little more control over how they sound.

Pros: They fit.

Cons: Too harsh, Too bright.

My truck was supposed to have 7 speakers and only had four. These really brought the front portion to life.

Pros: Amazing sound, crisp and clean.

Cons: None

Big sound in a small package

Written By Paul G, Arizona on Wednesday, December 10, 2014

Crutchfield Customer Review (What's this?)

I have these in the front center of the dash in my 72 Charger. Amazing speakers, fullness of sound and they can handle quite a bit of power when using the high pass filter. They rock.

Pros: Great sound in a small package

Cons: None

Written By Anonymous, AR on Friday, November 07, 2014

Crutchfield Customer Review (What's this?)

Good sound quality and a small package. Very pleased with the outcome. Installed in my 2011 suburban in about 90 minutes.

Pros: Sound quality. Price. Size. If I had it to do over again I would buy the exact same speakers.

Cons: Had to trim the backside of the plastic trim piece to install. Not really anyone's fault just something to think about if you're going to buy these for suburban.

Outstanding Speakers

Written By James W, Chesapeake, VA on Tuesday, September 23, 2014

Crutchfield Customer Review (What's this?)

Don't let the size fool you. The sound qualities of these speakers are night and day better than the so called "Premium Alpine System that came with the car. Clarity and proper sound is what these speakers bought to my Dodge Charger. This was money well spent for sure. Also a special thanks to my product advisor from Crutchfield for all of his help. If you are looking for some proper 3 ½ speakers don't hesitate to buy these.

Pros: Solid build, huge magnet, great tweeter. Speaker just reeks high quality.

Cons: Nothing

Great Dash Speakers!

Crutchfield Customer Review (What's this?)

What an Upgrade from factory speakers! Amazing difference. Now I am excited about upgrading other speakers as well. Thanks Crutchfield!

Pros: Amazing sound improvement

Cons: Didn't have factory connectors but easily solved with solder and a bit of wire. No biggie.

Crutchfield Customer Review (What's this?)

I bought these because one of my front speakers blew in my truck. I was happy with the sound of my Alpine system before one blew, I'm not an expert on speakers, but these speakers definitely made it sound even better. Installation was a snap with the provided gear from Crutchfield. 100% recommended.

recently purchased these to replace the factory speakers in the dash of my 2011 dodge ram. they made a huge difference and i am quite happy with them

Great Items

Written By 2014 Ram 1500 - Dash Great Speakers, Va Beach on Monday, March 03, 2014

Crutchfield Customer Review (What's this?)

Very nice speakers for the dash of the 2014 Ram to replace the Alpine system speakers. I recommend changing at least the left and right front dash and rear door speakers with a good 6x9. The front doors are NOT worth replacing since there is almost no improvement from any replacement due to receiver/amp controlled crossovers.

Pros: Great fit

Nice factory replacement.

Written By ET, Red Bank, NJ on Friday, January 17, 2014

Crutchfield Customer Review (What's this?)

I installed these in my Ram 1500 dash, replacing the factory speakers. I can actually hear the front speakers now! These little guys cost a little bit more, but it's worth it. Great tweeters and even a little nice soft bass coming from them. Highly recommend.

Pros: Sound great, nice tweeter and even a little bass.

Cons: None I can think of.

Infinity dash upgrade

Written By BillR, Raleigh NC on Sunday, January 12, 2014

Crutchfield Customer Review (What's this?)

Very good sound upgrade for price. They need an amp to supplement power from Kenwood receiver. Crutch field adapter kit was perfect for quick install. I will solder the speaker leads when I get more time.

Pros: Perfect fit for 91 mustang convertible dash

Cons: I would recommend sound barrier when installing in older model cars.

Excellent Dash Speakers

Written By Mark, Middle River, MD on Thursday, December 19, 2013

Crutchfield Customer Review (What's this?)

These two way speakers have really opened up the sound stage compared to the factory tweeters in the dash of our 2009 Mazda Cx-9. Installation wasn't bad but sure would've been simpler with a dedicated wiring harness to attach to the factory speaker connectors. Overall these were a good buy and I highly recommend them.

A Nice Improvement

Written By zt5159, Tulsa, OK on Saturday, December 14, 2013

I installed these in the rear doors of my 2012 Chrysler 300S with the so-called "Beats by Dr Dre" system. I say so-called because the speakers are the exact same ones Chrysler uses in its 2011+ 300/Dodge Charger Alpine audio systems and they are not impressive.

They sound much clearer than the originals and I can even feel a little bass from them! Which is something you do NOT get from the factory 3.5" speakers.

One thing to note is that in the 300 and Charger, these may fit just fine in the dash, but require a little modification to fit in the rear doors. The tabs for the mounting screws are too big, so I had to cut a corner from each one and then they slid into place and bolted down just fine.

I love them! Not quite for the price (for my particular upgrade) but if you can catch them on sale it's worth it. Or if you have a different system than I do, they might be a bigger improvement.

Pros: Sound quality, bass for their size

Cons: None yet

Dashboard speakers

Crutchfield Customer Review (What's this?)

Wow. These little guys did make a big difference. Installer was skeptical at fist. But now, I'm front row. The sound is clear w/out the over burden of the volume needing to be raised

Pros: For the cost it was an unexpected outcome in performance that it delivers. Overly impressed by its highs and clarity

Crutchfield Customer Review (What's this?)

Best 3 1/2 inch speakers Ive ever had. They give the music more clarity than you could ever imagine in your front speakers. The instruments are clear like they've never been.

Pros: They're the best 3 1/2 inch speakers Ive ever heard!

Cons: There aren't any!

Not Impressed

Written By Rick, Montana on Friday, August 23, 2013

Crutchfield Customer Review (What's this?)

I purchased these for my 89 blazer. Crutchfield says they fit with seperate brackets. They do not fit correctly, the dash metal braces hit the speakers when all is installed. These speakers are a cross between a mid and a tweeter. They try and reproduce mid level bass and high end from the tweeter. The mid sounds like crap even when adjusted crossover, with the mid trying so hard it makes the tweet sound like crap too. Get a combo mid and tweet seperate. You will be much happier.

Pros: They make noise.

Cons: The noise sounds like crap!

Great speakers for my 2013 Charger

Written By Mary, San Diego, CA on Wednesday, July 10, 2013

Crutchfield Customer Review (What's this?)

I replaced the Alpine speakers in the dash of my 2013 SRT Charger with these Infinity's. The difference is like night and day. They sound great and add the clear and crisp high's the factory Alpine's lack. Speakers also add a good amount of lows. All in all an excellent speaker at a good price.

Pros: Great highs, nice lows.

Cons: None

Sound crisp, & clean. yet powerfull enough to make sure they are heard with the other larger speakers.

Pros: Easiest to install

Great little speakers

Written By OC, Houston, TX on Monday, May 13, 2013

Crutchfield Customer Review (What's this?)

Speakers were purchased to replace dash speakers in an FJ Cruiser. They aren't supposed to fit but do with a small adjustment to the inside of the factory grill and placing a new hole for a mounting screw. 10X better response than from the full range speaker from the factory it replaced. Needs decent amount of power so I'll be buying a new Alpine MRX-V70 to allow these to really perform. More sound than you would expect from such a small speaker. Don't look for a 3 1/2" speaker to kick bass. Its a fill speaker

Pros: Well made, superb sound, very clear highs and mids

Cons: None

Infinity Reference X REF-3002cfx - 2012 Charger

Written By TAS, Colorado Springs on Monday, April 15, 2013

Crutchfield Customer Review (What's this?)

A great upgrade from the stock speakers! The stock dash speakers in the 2012 Charger were lifeless (base non-Alpine audio package). The Infinity Reference X REF-3002cfx brought out subtle details like whispers, cymbals, and reflected them off the windshield; soundscape expanded nicely. I added the PAC BB-600A2 Bass Blockers (600hz) to protect them. The included speaker wire adaptors worked great. In the right scheme, these speakers are a great supplement to your stereo system.

Pros: Added accurate higher frequencies, great improvement in vocals, in 2012 Charger took only about 45 min to get a great noticeable upgrade.

Cons: None

nice speakers!!!!!

Not Thrilled

Written By Dissapointed, Joliet, IL on Tuesday, January 15, 2013

Crutchfield Customer Review (What's this?)

These were recommended for my car through the Crutchfield fit your car app. The fit was fine but after 3 weeks noticed a popping out of one of the speakers and the sound clarity was not there. Called Crutchfield and asked if the speakers were the right fit and they confirmed but told me since I was out of the return window I was out of luck and to replace the speakers. I happened to purchase another set at the beginning thinking I had 3 speakers in my front dash ( I didn't). I replaced the speakers and still not thrilled with the fidelity of the system. I found that in my car the front factory speakers are 8 ohms not 3 ohms as suggested and now am not sure if this is the wrong selection for my car. Crutchfield told me now to buy the amp upgrade to make it sound good but now I am forced to an upgrade that I was not really looking to do. This was my first experience with Crutchfield and for me they have failed in both the product and the customer support.

Pros: Good clarity at low volume

high hopes

Written By ricky, Carol Stream, IL on Thursday, September 06, 2012

Crutchfield Customer Review (What's this?)

The speakers appear beautiful. And the infinity brand is strong. But the reality is that they much dont handle much bass. The highs are good mids are good. Use hpass. They are ok. I rely mostly on the sound of my Rockford Fosgate 6x9s. Heavy rear fader bias.

Pros: Brand.

Cons: Crackle and pop with any bass.

Infinity Reference X REF-3002cfx

Written By Croft, clarkston,MI on Friday, March 23, 2012

Amazing speakers. More bass in these 3" speakers than the stock 4" speakers. Less distortion too. But these do fit a 2004 saab 93 if you grind down the inside of the grill. Just grind down the little hexagons. That extra 3/8's of an inch will make it flawless. you cant even tell there in there.

Pros: great highs and lows. Great sensitivy too

Cons: a little work to get in there for my certain car

Get everything you’ll need to enjoy your new Infinity Reference X REF-3002cfx

Reduce ambient road noise and your vehicle's "rattles," for better sound inside your car.
You may need speaker wire to connect your speakers to your amp or receiver.
Keep your speakers clean and dry. They compress to fit behind your speakers.
These speaker connectors are handy if you're running new speaker wire or if your speakers have oversized terminals.
The right tools will help keep your installation simple and clean.
If your stereo doesn't cut the deep bass from your full-range speakers, a set of bass blockers can help prevent distortion and give you cleaner bass too.
