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.

I installed them in a 2003 Chevy Truck. I am not sure about a 2014 GMC.
[ Valerie  Feb 03, 2019 ]
Not sure but I tell you what go with hertz audio speakers after it was all said and done $1200 later and 3 sets of speakers. Hertz compent speakers are the best I've ever purchased
[ RICARDO  Feb 03, 2019 ]
I just purchased and installed these speakers. I have an older JVC head unit with 25 watt per channel power. I have also purchased 2 JBL Stage 9603 3 way 6x9's. I planned on running them off the head unit as well. Should I install a bass blocker to the Infinity's so that I can turn up the volume and allow the 6X9's to handle the mids and bass? What should I also do differently if I add a sub and amp to this setup? Would I also need to add bass blockers to the 6x9's? or should I go to a crossover at that point? would I need to do anything differently to the 3.5's if I added a sub and amp? Thanks in advance for your reply.

Sounds like a solid setup. Did you use the bass blockers included with the Infinity tweeters? If not I would put them in there.
[ PAUL  Apr 24, 2018 ]
I believe your 25 watt/channel JBC head unit will run your speakers fine as is. If it were me, I would install the infinitis as they are. You can always go back and add bass blockers if necessary. I also installed a self powered JBL Bass Pro to meet my bass needs without having to add a more powerful amp. I found a refurbished one from JBL for a very reasonable price. Good Luck.
[ Patrick  Apr 24, 2018 ]
Just run the 6x9's from it's own amp no need to add a bass blocker for them. You might want a bass adjuster.
[ RICARDO  Apr 24, 2018 ]
I would add the bass blockers for 3x5's and add an amp for the 6x9's alpine or JL audio I've had both prefer JL. Add a sub JL audio don't go smaller than a 10inch sub if you ask why JL??? again if you space issues the have you covered the quality is 2nd to none.I got my doors sound deaden made such a difference for my 6x9's. Sounds tight with no distortion. The 3x5's will need to be adjusted they are really bright at times you might be in the negative but the clarity will amaze you.
[ RICARDO  Apr 24, 2018 ]
are there instructions on how to remove the dash cover to get to the factory speakers for replacement? Thanks.
