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-3032cfx 3-1/2" car speakers remain a popular choice for replacing factory speakers because of their competitive pricing and superb sound.

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-3032cfx 3-1/2" car speakers remain a popular choice for replacing factory speakers because of their competitive pricing and superb sound.

Infinity's famous ingredients

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. Add to all that, a 1/2" textile balanced dome tweeter for clearer and smoother highs, and you have a sound that's definitively Infinity.

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.

Grilles are not included; the factory grilles should be suitable for most applications.

Product Research


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.

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.

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.

Crossover: The included 270 microfarad capacitors are 1st order high pass crossovers (6 dB/octave); the crossover point is approximately 196 Hz. One capacitor is wired in-line with the positive input of each speaker. For best results, solder speaker wire terminated with quick slides (item number 120FQS10PK, sold separately) to both ends of the capacitor, then insulate the assembly.

Customer Q&A

Do you need to break in after installing speakers?
[ JINGXIANG  Dec 21, 2022 ]
1 answer
Greetings Raymond, and thank you for your question. Speakers do have a period where they need to loosen up. After a few hours of running, most will sound better. If you are running a high powered amplifier to your new speakers, I would play them at a lower volume level at least for a few hours.
[ Thomas  Dec 21, 2022 ]  Staff
I am new to this and don't know terms or anything, but will installing these take away loudness from my front door and rear door speakers? I have a ram 1500 classic quad cab and will be installing Infinity Reference REF-9633ixon the rear doors and Kicker 47KSC504 on the front doors. I want to make sure the dash speakers don't take away the power from the door speakers.

[ ZACHARY  Dec 01, 2022 ]  Staff
Can anyone clarify what Infinity means when they state "speaker's 3-ohm impedance combines with speaker wire impedance for a 4-ohm load"? Makes no sense. Please advise. Thank You
[ TONY  Oct 30, 2021 ]

Infinity bills a very high efficient speaker. You don't need that much power to get a full affect of sound through your speakers.Enter an answer to this question.
[ DAVID R  Oct 31, 2021 ]
Should I use bass blocker on 3.5" if I am running an after market amp with a stock head unit?
[ David  May 17, 2021 ]
1 answer
I definitely would. Rather be safe than sorry, I have them on my truck and I've had them for about a year and a half and they work great
[ BRANNDON  May 24, 2021 ]
Will this fit into my center dash speaker in my 2015 mustang gt? Does it come with a wire harness or do I have to cut into the factory setup? And recommendations?
[ Blake  Apr 12, 2021 ]
3 answers
Yes it will fit, I installed into my buddies 2021 GT with the 9 speaker setup from factory. Fits right in, bought a wire adapter from Amazon.
[ Robert  Apr 18, 2022 ]

[ KRISTINA  Apr 23, 2021 ]  Staff
I am not sure if it will fit your vehicle, but they come with everything needed to attach without cutting the factory wires.
[ JAMES  Apr 12, 2021 ]
Want to put them in my 2012 Chrysler in the dash corners. Would my phone calls come through clear as well when using my car Bluetooth?
[ MARVELL  Nov 13, 2020 ]

I installed them in my daughters Jeep They work good. Clear sound
[ JACK  Nov 13, 2020 ]
I put these in a 2015 Ram 1500 in the dash corners. The improvement over the stock speakers was dramatic, for music and phone calls. I was very pleased with the sound.
[ Mark  Nov 13, 2020 ]
[ JAMES  Nov 13, 2020 ]
Will these work well with a 55watt amp (55 per channel)? Or would that be too much?
[ Elias  Sep 12, 2020 ]
1 answer
That should be fine. I am running them at 50-watts per channel, and speakers will distort a little, depending on the crossover setting; I tend to keep it at 100 Hz, but for mid-bass/high, they will sound great. Unless it's true 55 RMS, your amp. will not always put out 55 watts to all channels, so I would not be too concerned about blowing these speakers. I did not break into my speakers yet, as my I don't play music long or loud enough over time. But if you run these speakers through a well-tuned amp., then the voice coils will shine as Reference over time. :)
[ Phosy  Sep 22, 2020 ]
can this speaker be used as a marine speaker?
[ SYLVESTER  Aug 30, 2020 ]
2 answers
The material used in marine speakers may be different. I suggest buying speakers that are specific marine speakers.
[ Michael  Aug 30, 2020 ]
Not sure , but for its size with 40 watts pushing them they're awesome. My brothers boat came with Sony marine speakers
[ KEVIN  Aug 30, 2020 ]
With my expertise in automotive audio that equates to knowing how to turn it on and then off and maybe back on again, I was told that the factory dash speakers on my 2019 Ram 2500 BigHorn are 8ohm but these are 4ohm. It's suggested I add a 4ohm resistor to each speaker will have them sounding "right" . Could someone talk me off the ledge here with layman's terms please? Thank you.
[ CHARLES  Aug 05, 2020 ]
3 answers
I would check your car mfr.'s spec. for those dash speakers to see if they are a combo speaker and tweeter in-line setup. Mine is, so my tweeters have a "filter" in-line with my door speakers, so that filter cuts off the lower bass to the tweeters. A filter or OHM resistor is needed for these small dash speakers to work, else, they will likely blow from trying to play mid-low bass sounds, and this should come with the speaker already, which mine did. Hope this helps.
[ Phosy  Aug 11, 2020 ]
Hi Charles I'm just like you. But chat with one of the Great Crutchfield team members and they will be able to help They are all great in answering any questions Chat online or call Sorry I couldn't help
[ JACK  Aug 07, 2020 ]
Not an expert by any means myself. Mine was used as an upgrade to a center channel speaker on my F150. Researching produced multiple accounts of the speaker hardly doing anything for improved sound quality and many said they deleted the speaker altogether. I did end up using this speaker as a replacement. That being said, not sure if you are in same situation. Not a hard project. You could simply cut the supplied + speaker harness and solder splice the 4 ohm resistor in line. That way you still have your slip-on spade connection to the speaker. Easier, but not at all professional, would be "rigging" it with butt splices, which I would not suggest or do personally. If unfamiliar with soldering, run a YouTube on it. Very easy if you are set on these speakers. I am really surprised that Crutchfield wouldn't provide this with a "ready harness" option?
[ Brian  Aug 05, 2020 ]
Want to install in the dash of a 2020 Ram base 8.4", should I install Bass Blockers as well?
[ Earl  Jun 26, 2020 ]
4 answers
Not sure if this helps, but my factory dashboard speakers came with built-in low-frequency blockers, so I did not have to install any. My mids in the doors, and tweeters on the dash get their HP frequency filtered automatically. If your Ram came with original tweeters, could it have blockers already in-line? If not, a bass blocker can only help to protect those tweets from LF damage.
[ Phosy  Jun 29, 2020 ]
I have mine in a 2016 Ram and have never had a problem with them. I've had a stock radio and an aftermarket radio and never had them pop.
[ Dallas  Jun 26, 2020 ]
Did mine some time ago. Did not need bass blockers and haven't experienced any distortion.
[ duran  Jun 26, 2020 ]
Yes, to have distortion free listening!
[ JAMES  Jun 26, 2020 ]
What are the capacitors used for and how should they be soldered?
[ MATTHEW  Apr 02, 2020 ]
1 answer
Capacitors are used to filter out the bass to whatever speaker you don't need bass to. But they get extremely hot so place them in a area so they won't touch anything. The speakers that you questioned about come with them and the instructions tell you how to do it.
[ BRANNDON  May 24, 2021 ]
What is the bolt hole mounting center to center measurement?
[ Ian  Feb 01, 2020 ]
2 answers
Center to center, they are 4.1" apart when measuring diagonally across the speakers
[ JASON  Mar 09, 2020 ]  Staff
I don't remember 100%, but I either used the included Philips screws or the original factory screws to mount these speakers to my car's dashboard corners just fine.
[ Phosy  Mar 08, 2020 ]
Is it a direct fit to a 2019 Camry or does it need a bracket?
[ Ahmad  Jul 14, 2019 ]
1 answer
I bought mine for dash speakers for 18 Subaru Crosstrek. Fit perfectly. I piggybacked connections to original connectors. Work fine and can remove if I decide to get rid of car and want to put originals back.
[ Drew  Jul 15, 2019 ]
