Rely on Infinity to revitalize the sound in your car. Replace your tired-out, old factory speakers with Reference Series full-range speakers that'll play your music louder and better.

Infinity Reference 6432cfp 4"x6" plate speakers feature a Plus One+ woofer design that maximizes cone surface area so you enjoy richer, deeper lows. Large textile dome tweeters project smooth, clean highs, and they're equipped with a level control so you can fine-tune the degree of brightness to match your taste. Large voice coils in the edge-driven textile dome tweeters allow for high power-handling. The woofer and tweeter are mounted separately so you get the superior sound of components in a plate that installs easily in your 4"x6" opening.

Important Note: These Infinity Reference speakers use a low impedance design to pull more power safely from your car stereo or amplifier. This design is compatible with virtually all factory and aftermarket stereos.

Installation Note: These Infinity speakers do not include screws or speed clips. You may be able to use the factory screws to install them, but it's always a good idea to have an assortment of self-tapping screws (5/8" to 1") and speed-clips on hand.

Bought these speakers to replace the rear speakers in my silverado. I requested a speaker that would sound good with the stock radio. These speakers sound great.



Great speakers that work with factory radio's

Crutchfield Customer Review (What's this?)

Great replacement sound for the front speakers in my jeep. They can be used with factory radio! So easy to install, only 20 minutes per speakers to install. Would buy again in a heart beat. ( make sure you buy the kit for installing them)<br> <b>[Editor's Note: The adapter needed to install 4x6" speakers in the wrangler dash is no longer available. We now recommend 4" speakers for this location.]</b>

Crutchfield Customer Review (What's this?)

I was ready to send these back because they did not fit the speaker location. I made them fit!!! The sound is better then the Infinity Reference components that are in the front. I have a clean 50watt rms per channel Alpine amp pushing them and they are clear at high volumes. "M" azing.



Great, paired with 5022i's

I just installed these under the dash in my Jeep wrangler, and they sound awesome. Pros: clear crisp sound easy installation I love the tweeter boost switch Con: Bass-shy because they're so small... but don't let that stop you, pair them with a sub and you'll have an amazing listening experience.

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 a significant increase in efficiency.

Woofer Materials: Each woofer is constructed from Injection-Molded Polypropylene. This process of cone molding assures a uniform cone thickness for superior linearity and clarity. It is also lighter weight and more rigid for decreased distortion and improved bass response.

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.

Textile Dome Tweeters: Each speaker uses an edge-driven textile dome tweeter for smooth, accurate highs. A switch on the front of the tweeter allows you to boost the tweeter output 3dB, useful if the speakers are mounted low in a door where high frequencies are easily absorbed.

True Four Ohm Impedance Technology: The speaker's 2.0-ohm impedance combined with the impedance of your speaker wire provides a true 4-ohm load to your connected headunit or amplifier.

Mounting: The speakers can be mounted in a metric 4"x6" opening, or a U.S. standard 4"x6" opening.
