Reference Quality Sound from Infinity

Never has getting high-end sound in your car been easier. The Infinity Reference 9633cf 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 9633cf.

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.

if you are looking to upgrade your sound these are the speakers. They are clear and crisp. For the price you can't get a better set of speakers. Well worth the money. I would recommend these speakers.

Currently running them on 220 rms each and they sound super crisp. I wouldn't recomend doing this but for the matter, they have been ran like this for about 6 months. Awesome sound and good power handling.

These speakers sound very good. I got similar sets for my F350 and sets for my wife's 2007 Sienna minivan. I compared them to the components (individual) separates mid/tweeter and I think these sound better than the more expensive speakers. Regardless, they sound so much better than the oem speakers that came with the truck/car, it is silly to keep the original crap in the vehicle. Great price, quick shipping. a no brainer!
