Reference Quality Sound from Infinity

Never has getting high-end sound in your car been easier. The Infinity Reference 5032cf car speakers are the perfect solution to aftermarket speakers. With the 2 ohm voice coil, these speakers are ideal for running directly off of a headunit or for use with a aftermarket amplifier. Infinity engineers have combined the Plus One+ cone with the high roll rubber surround to help retain the integrity of the sound. The edge driven, textile dome tweeter also features a tweeter attenuation switch that will adjust from 0 to +3 dB. Get more from your audio system with the Infinity Reference 5032cf.

True Four Ohm Technology

The engineers are Infinity have developed a speaker that works for all applications. The True Four Ohm Technology used in these speakers make it perfect for running directly of a headunit or with an aftermarket headunit and amplifier. All of the speakers in the Infinity Reference line feature a 2 ohm voice coil. However, when you factor in the small OEM speaker wire of most vehicles and the heating in the voice coil during use, the impedance actually seen by the amplifier will increase. Infinity has adjusted the speaker to be safely connected to any headunit.

Speaker Specifications

This is the manufacturer product line of speakers.
Reference (Infinity)
Priced Per
Car Speakers are typically sold in pairs so you will receive 2 speakers for each speaker purchase on speakers marked "Priced Per Pair". If a speaker is marked "Priced Per Each" then the speaker is sold individually and each purchase you make will result in 1 speaker. High-powered tweeters, midrange and full-range pro audio for car speakers are typically sold per each speaker.
Speaker Size
Refers to the size of the speaker measured in inches. Every vehicle has standard application sizes. Please use our vehicle fitment guide for your vehicle's specific speaker sizes if you do not know them.
The number of individual drivers in a car speaker. Speakers with 2 drivers are known as a 2-way, and 3 drivers are known as a 3-way. Component systems are often referred to as "separates" because the tweeter is not attached to the midwoofer (main speaker driver) and mounts separately in a location such as a door post. Component systems typically come with an external crossover so you can easily adjust the high and low frequencies sent to both the midwoofer and the tweeter. Center channel speakers are great for those looking to have surround sound in their vehicle.
Tweeter Design
Designs such as cone, dome, semi-dome, balanced dome, and whizzer are most popular. Cone tweeters are simple, efficient and typically are the most reasonably priced. Dome tweeters are used in most home speakers, and provide a smoother and more accurate sound. Semi-dome design is one with a dome placed inside a cone. A Balanced dome driver is a semi-dome with equal reproduction area given the cone and dome portions of the driver. A whizzer tweeter is a separate tweeter cone driven by the voice coil of the woofer.
Tweeter Composition
Materials such as polypropylene, silk, cloth, and paper are the most common, where as many more recent tweeters are now manufactured with composites such as Aluminum, Titanium, Mylar, and other materials.

PEI is an acronym for "Polyetherimide" which is an amorphous, amber transparent, high-performance thermoplastic.

Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Injection Molded Polypropylene (IMPP)
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
135 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
45 watts
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
92 dB
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
67 - 21,000 Hz
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
2 ohms
Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
3-7/8 x 3-7/8 
Speaker Grilles
A grating or screen of metal or plastic bars or wires, mounted in front of a speaker as protection. If yes, the speakers will include matching speaker grilles. If no, there are no grilles included.
Number of Speakers
This is the number of speaker that is included in the package. Each purchase will result in receiving the number of speakers indicated here. Please note that some items will have multiple woofers in the same enclosure. For sets of component speakers, this number will refer to the number of sets of speakers (For example, 2 would indicate the purchase includes 2 woofers and 2 tweeters).

Please refer to the product image and description for further details about the speaker.

Great sound quality

Great Mid-Range!

September 5, 2013

These will go great as an upgrade from stock speakers. The integrated amp in most aftermarket head units should be just about perfect for these. I have an outboard compact amp but can't get too crazy with the gain just yet. The sound quality is beautiful but can benefit from an additional sub. Well worth the money but I plan to upgrade to the Kappa series soon or something similarly a bit more power hungry. Installed in a regular cab pickup in two pairs.

clean and sharp

November 15, 2013

sound really nice installed them in my 2000 jeep wrangler, in the head bar which i realized after installing them i could of gotten a larger speaker like a 6 or 6.5". Like i said there crisp and sharp but defiantly need a mid woofer or sub woofer to get your low hits, but they defiantly have the mid to high output. and its very convenient that they have directional tweeters and a switch to go from 0db to 3db.

Good Sound, But Low Power Handling

April 26, 2012

I bought these to replace blown factory rear speakers in my Ford Probe. They sound good but I wish they could play a little louder. Using an in-dash 20 watt CD radio, these speakers will pop on transients when pushed a little (I listen to classic pop and rock).

I kept them and am using them daily, but I faded the sound a little to the front speakers, which are stock, to get a few more dB of level out of the system. I also rolled off some of the lows to these rear speakers. Looking back I probably should have gotten the next Infinity's up, which have better power handling.

However, these have very nice highs and sound good up to their limits. Most people probably don't listen as loud as I do and these would be good for background-level listening or as rear speakers that don't have to carry the whole load.

Clearest sound for the money!

February 16, 2012

Had these in my old '94 civic 4 door. Hugeeee improvement over stock and fitment was almost perfect. Just needed to purchase a spacer to clear the oem housing. The speakers themselves are fantastic, lack bass but thats what subs are for! Thinking about getting them again for my new civic.

niles, OH

scored for half price!

August 12, 2014

I picked these up because they matched the 6x9s I bought and because they fit in the existing holes of my mini cooper. They just happened to be on sale for 57 dollars. I couldn't be more satisfied with the purchase. they sound fantastic.....with or without the value. Id buy em again even if I had a lot more to spend.

will my amp see 2 ohms or 4 ohms with these speakers?
taylor y on Sep 7, 2014
Best Answer: Apparently these speakers claim a 2 ohm load but actually present a 4 ohm load by including the resistance of the speaker wires themselves. I connected them to a Pioneer head unit that said to NOT connect 2 ohm speakers but I did anyway and it works just fine.
