About the Infinity Reference X REF-6402cfx
Designed for more clarity
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-6402cfx 4"x6" speakers. Infinity uses textile dome tweeters to give you amazing levels of detail without sounding harsh.
Larger woofer for more bass
The REF-6402cfx 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 45 watts of RMS power — they'll work great with 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 — factory grilles are appropriate for most installations.

Features
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 increased 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.
Textile Dome Tweeters: Each speaker uses an edge-driven textile dome tweeter for smooth, accurate highs.
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 6402cfx speakers at 45 watts RMS (continuous average), they also recommend amplifiers with a power rating from 5 to 50 watts RMS.
Bottom Mounting: While the standard 4x6 adapters appear to be easily removable, they are glued in place at four points around the perimeter (in addition to the four screws, which are obvious). With the adapters in place, the speakers fit many top mount standard 4x6 and metric 4x6 applications. If the adapters are removed the speakers will fit additional top mount metric 4x6 applications, as well as bottom mount metric 4x6 applications.

I replaced the worn out speakers in my 2003 Silverado with these speakers. The installation was pretty easy with the helpful links on the website. The speakers sound great and I couldn't be happier. I might just look into a new radio in the future to go with the new speakers.
