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-4032cfx 4" 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.

Connectors not included

Daniel from Americus , GA on 2/12/2019

Verified employee purchase (What's this?)

It sound petty but I was amazed to find that the basic connectors were not included with "quality" speakers. I was hoping that Crutchfield would provide them after I called but they only confirmed thier absence and provided the spec for the connectors I needed. Living in a small town, I had to drive 45 minutes to the next town to a radio installer to pickup the connectors. Also missed the sale by a couple of days. Could have saved $50 on the two sets I purchased.

When shopping vehicle specific speakers check speakers first. I was sent the wrong speakers for my vehicle. After receiving the wrong speakers I measured my factory speakers and the online vehicle specific search said the speakers that I needed "after I measured the factory speakers" wouldn't fit my vehicle.

Clean Sound

Verified employee purchase (What's this?)

I was able to mount these in my BMW 335i front doors, and I would have to say it is a huge improvement on the stock speakers. Definitely found that it is more crisp the sound. Best bang for the buck!!

Pros: Clean sound, huge improvement on stock BMW speakers

Cons: None.

Verified employee purchase (What's this?)

The speakers were very easy to install whole job took less then 20 min. Yet the sound quality made a world of difference, which surprised me for just 4" speakers. I wished I had changed them sooner.

Pros: Good price, great sound

Cons: None

Amazing sound with the top off

Tebra from Moore, OK on 9/16/2018

2005 Jeep Wrangler

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

They make a huge difference in sound in our Jeep with the top off! Crisp, clean sound that you can hear and understand. Came with a hard rings adapter that we used to make it fit. It was not recommended for our vehicle but we are so glad we used them anyway.

Pros: Amazing sound

Cons: Doesn't really fit our jeep

Verified employee purchase (What's this?)

I bought this to replace my stock rear speakers of my '92 MR2. I wanted Infinity's to match my Reference 6032si in the front doors. Great price that fit my budget. They're larger than the stock speakers but fit no problem. Much improved sound!

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.

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.
