Why replace your car's original speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

Our take on the Infinity Reference 9633cf

by Buck Pomerantz

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 9633cf 6"x9" speakers feature a Plus One+ woofer design that maximizes cone surface area so you enjoy richer, deeper lows. Textile dome midranges and tweeters project the mids and highs with precision, covering the entire musical frequency spectrum for true-to-life reproduction of vocals and instrumentals. Large voice coils in the tweeters allow for high power-handling. Grilles are not included — factory grilles are appropriate for most installations, but optional grilles are available.

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.

Highlights:

  • 6"x9" 3-way speakers (pair)
  • Plus One+ Injection-Molded Polypropylene (IMPP) woofer cone with hi-roll rubber surround
  • edge-driven textile dome tweeter and textile dome midrange
  • True Four Ohm Impedance technology: speaker's 2-ohm impedance combines with speaker wire impedance for a 4-ohm load
  • compatible with virtually all factory or aftermarket car stereos
  • optional grilles available
  • power range: 2-100 watts RMS (300 watts peak power)
  • frequency response: 46-30,000 Hz
  • sensitivity: 94 dB
  • top-mount depth: 3-1/16"
  • warranty: 1 year
  • Our 60-day money-back guarantee

    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 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 Midrange and Super-Tweeter: Each speaker uses an edge-driven textile dome midrange and a UHF super-tweeter for smooth, accurate highs. A switch on the front of the tweeter housing allows you to boost the tweeter output 3dB, useful if the speakers are mounted in a location where high frequencies are easily absorbed.

    Mounting: Infinity's mounting system allows the 6932cf speakers to fit in top-mount and bottom-mount 6"x9" applications.

    Optional Grilles: The speakers do not come with any grilles. Optional grilles (108REF9633) can be purchased separately.

    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.

    Written By yaris, ny on Saturday, June 02, 2012
     
    i have a 2008 toyota yaris i replaced my head unit, after i did that the speakers sounded much better. i recently hooked up a amp and they make the car vibrate. the highs and lows are heard verry well and the bass kicks, well worth the price.
    Pros:
    quality and clean sound at high volume
    Cons:
    none

    Fantastic speakers, very clear sound

    Written By Wesley, Columbus, OH on Tuesday, October 06, 2009
    Installed in a 1999 Saab 9-3
    Crutchfield Customer Review (What's this?)
     
    I purchased these to replace the stock speakers in my 1999 Saab 9-3. The Crutchfield website stated that they wouldn't fit, but I managed to get them to fit using the included spacer ring. I went out and purchased some different metal screws, however, as the screws included weren't long enough for my needs (not a problem since it was a somewhat custom installation at that point).
    I also soldered wires to the speakers instead of using faston (blade) connectors, which these speakers use. I don't plan on moving them anytime soon, so not a problem.
    I'm powering these with an Alpine 300 watt 4-channel amplifier, and they sound fantastic. The 3-way system is definitely noticeable -- the woofer is pretty powerful (especially with both speakers installed) for a 6x9", and the mid-range and tweeter speakers make for a very clean sound of voice as well as instruments.
    The only complaint I have about the speakers is the fact that the screw holes are extremely close to the rubber surround -- first trying one of the stock screws (not the ones I later purchased!) the screw managed to catch some of the surround's glue and rip a bit of the glue out. I added a drop of gorilla glue and that fixed it.
