 REF-8602cfx 6Designed 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-8602cfx 5"x7"/6"x8" speakers. Infinity's UniPivot design allows you to aim each textile, edge-driven tweeter toward your ears, so you enjoy excellent stereo imaging even if the speakers are mounted way down low in your doors. Each tweeter features a level control switch so you can boost the brightness to your taste.

Larger woofer for more bass

The REF-8602cfx appeals to bassheads too, with tough polypropylene woofers and durable hi-roll rubber surrounds that deliver strong low-frequency 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 60 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.

Product Highlights:

  • 6"x8" 2-way speakers (pair)
  • Plus One+ polypropylene woofer cone with hi-roll rubber surround
  • 1" UniPivot edge-driven, textile dome tweeter
  • True Four Ohm Impedance technology: speaker's 3-ohm impedance combines with speaker wire impedance for a 4-ohm load
  • compatible with virtually all factory or aftermarket car stereos
  • power range: 5-60 watts RMS (180 watts peak power)
  • frequency response: 49-21,000 Hz
  • sensitivity: 93 dB
  • top-mount depth: 2-7/16"
  • warranty: 1 year
  • Our 60-day money-back guarantee

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.

Product Research


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 (UniPivot Design): Each speaker uses an edge-driven textile dome tweeter for smooth, accurate highs. The UniPivot design mounts the tweeter at an angle and pivots, so the tweeter can be pointed at the listeners, optimizing the stereo image for a more uniform response. The tweeter housing can be turned approximately 315 degrees.

Tweeter Level Control: A switch on the front of the tweeter allows you to boost the tweeter output to +3dB, useful if the speakers are mounted low in a door where high frequencies are easily absorbed.

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 8602cfx speakers at 60 watts RMS (continuous average), they also recommend amplifiers with a power rating from 5 to 125 watts RMS.

Infinity reference speakers

Written By Rlarson, Juneau, Alaska on Monday, March 23, 2015

Crutchfield Customer Review (What's this?)

Very nice product. I decided to purchase Infinity again, first purchace nearly 20 years ago for Infinity 152's for my home speakers. Quality is still there. These have completely upgraded the audio in my 99 F250. Looking forward to replacing the head unit to get the most out of them. I already had an amp and a name brand subwoofer installed and these stepped it up a notch. My money was well spent!

Pros: Ease of installation

Cons: None

very good upgrade

Written By Bill K, Illinois on Monday, March 09, 2015

Crutchfield Customer Review (What's this?)

Have a new 2014 Ford F-150 Super cab........ and I don't know when Ford will get the message that their $8 china made speakers are absolute crap! After paying that much for the truck, I expected better......... however, after installing these Infinity's's a world of difference. I did not upgrade the standard receiver unit because of all the integration that comes with it and I am unsure of how to do it. But these speakers easily place at twice the volume with clarity and NONE of the boominess that the original speakers had. Installation was very easy with Crutchfield's instructions and their install kit. Just be sure that you hear the "click" when connecting the Crutchfield wiring adapter to the original Ford speaker cable harness. I had to take off the door panel one more time after I installed it the first time, (because I didn't full seat the speaker wire harness adapter connection). But once that was done, the second door took no more than ten minutes.......what a world of difference...... and they can crank pretty loud too, with just the original Ford head unit.

Pros: Super easy to install in with no mods and you just can't be the clarity of these things! Tilt the tweeter up and push in the 3db button on the front of the speaker before you install them and you will wonder why you waited so long to upgrade from those horrible things that come with the original truck.

Cons: None, but you may want to put on the foam rubber stick on pads (on the back of each speaker, takes only seconds) that come with them, just to keep any unwanted vibrations from happening. You don't really need them because they tighten up so good against the door, but I did it anyway just for insurance.

Crutchfield Customer Review (What's this?)

Outstanding speakers. Very nice highs without getting tinny. Being used with a sub so speakers are crossed over at 120 hz, so it makes very clear mids.

Pros: Installed very easy. Incredible sound

Cons: Sorry, none.

Great quality speakers!

Crutchfield Customer Review (What's this?)

Smooth, clear, balanced mid range, treble, adequate base for the size of speaker. Easy on the ears, very little strain. Nice details in the music even though they are in truck b most of the [offsiteUrl] down back roads

Pros: High quality product, always seem to buy Infinities, never a bad experience. Easy install, piece of cake with the supplied cables.

Cons: Wish the Ford F150 could hold a larger speaker for a little more bass, no cons for the Infinities

Crutchfield Customer Review (What's this?)

I have used Infinity speakers for many years on various vehicles. I finally got around to replacing the stock speakers in my 1999 F-150 Supercab. Night and day difference. Not overpowering with bass or low tones. Crisp clear sound! Love them!

Pros: Quality product at a decent price. Usual Crutchfield top notch service

Cons: None

Crutchfield Customer Review (What's this?)

These speakers are awesome. They are extremely clear. I love the way you can hear each tap on the hi hats and the sound of a drum stick on a ride cymbal. The bass is good and its clean. The factory speakers had excellent bass but they were muddy sounding, but the infinity are so clean sounding.

Pros: Excellent highs, good clean bass.

Cons: none

Written By Schalk USN, Shawnee Kansas on Thursday, December 11, 2014

Crutchfield Customer Review (What's this?)

Purchase the speakers just after Thanksgiving 2014. I bought one pair and got another Free Crutchfield sent all the necessary paperwork speakers installed with ease. You can install the speakers without taking the door panel completely off. Just use a prop at the bottom of the panel to hold it open. This way you don't have to disconnect all the cabling for the door handle.

Pros: Speakers do sound very nice. They are 5x7 in and all doors.

Cons: None

Written By strongarm, Sarasota, Fl on Thursday, December 11, 2014

Crutchfield Customer Review (What's this?)

Got these to replace my OEM speakers without the factory sub of my '13 F150.

Installation was simple (be sure to use plastic pry tools!)

So far, they Mid's and high's are great. I have basic EQ control with my sync head, and you can't beat these. I got them on black Friday (BOGO!) but was going to buy them a month earlier even if they weren't BOGO.

Will be installing another set in my other car and perhaps adding an amp to give them more life with a small simple sub.

Pros: Quality, look, sound

Cons: None

I bought these to replace the poor factory speakers in my 2011 F150. The Infinity speakers produce a rich, full sound.

Pros: Easy install. You can aim the tweeters where you need to according to application.

Cons: None. Wish I would have bought them sooner.

I now get clear crisp sound. Easy installation with the instructions provided.

low price high performance

Written By rude dog, Charlotte,NC on Monday, October 13, 2014

Very impressed with these speakers for the money they can't be beat.I've had expensive speakers and cheap speakers these are without a doubt the best performing speakers I've had they even out perform some that cost way more!If these sound horrible to you always double check phase I've made that mistake myself crossover and tune properly you'll be satisfied!

Pros: Clear,directional tweeters,efficiency is good enough to be ran off a head unit but amps are always better to reach full potential with clean amp of course.Easy hook up

Cons: ANY speaker should come with grills this could be a selling point for some people. 2ohms would be better if pairing with amp however 3 is better for a head unit.

Sounds Great

Written By DarronsDad, Iowa on Wednesday, October 08, 2014

Crutchfield Customer Review (What's this?)

I have put these speakers in a 95 Mustang, 99 Ranger Extended cab, and now a 98 F150 Extended cab. I purchased all from Crutchfield. If you like your tweeters the +3db setting should be depressed to take advantage. It really brightens the sound and that is something I like.

Pros: With the exception of the Ranger They all sound incredibly better than the stock speakers. They were easy to install and the hardware sent with them connected perfectly. The install instructions are fairly easy to follow and you do not have to drill any holes or make any modifications.

Cons: The only problem with the Ranger was with the rear speakers and that was not the fault of Crutchfield. They really rattled the rear doors. I should have purchased the recommended boxes or inserts to dampen the spaces. I know that will make the bass not have as much punch but would probably stop the rating.

Great Speakers

Written By Damon, Naples, FL on Sunday, August 24, 2014

Crutchfield Customer Review (What's this?)

I purchased these speakers for installation in the doors and rear deck of my 2014 Ford Mustang. The speaker wire harnesses provided by Crutchfield were a perfect match, and the Master Sheet instructions were informative. Installation in the doors was easy. The rear deck was more difficult, but simpler than I imagined. Once installed, I did not use the +3dB Tweeter Level Control on any of the speakers. Originally, I installed these speakers without an amplifier. They sounded clearer to me than the stock speakers, but the bass response I was hoping for was not there. My car stereo was, and still is, the stock unit. Afterward, I installed the JL Audio XD700/5v2. Once the Infinity Reference X speakers had the power of the amplifier behind them, they sounded incredible to me. The bass response is definitely there. I can place my hand over the "grill" holes in my plastic door panel, and feel the air move during kick drum hits in rock music or bass notes in hip-hop, etc. The frequency of the speakers are quite good and they reproduce a lot of the bass frequencies quite well. If you purchase these for a vehicle, I highly recommend matching an amplifier to them. The difference is night and day to me. I also installed the JL Audio Sealed BassWedge (CS112-WXv2) to compliment my setup, and it's perfect for my needs. Even with the subwoofer in the trunk, I don't use the high-pass filter (on the amplifier) for the door speakers. They just sound great to me, and I'm completely happy.

Pros: Easy to Install, Great Sound

Cons: None

They Sound Great as Expected

Installation was a breeze with the included instructions. The sound is a big improvement to the factory speakers. Well worth the money paid.

Proper sound

Written By Chris, Glens Falls, NY on Monday, June 02, 2014

Crutchfield Customer Review (What's this?)

These aren't going to thump your crappy sub-compact car down the street, but they will give you a very broad spectrum of accurate and pleasing audio. I'm a recording engineer by trade and these are as good as you can get unless you're willing to use an amp and spend a lot more $$$ per speaker.

Pros: Accurate, non fatiguing, smooth

Cons: For BEST results, they really should be amped. Not bad at all from factory deck/amp though!

Cons: NONE

Terribly disapointing

Written By Virgil, Texas on Thursday, April 17, 2014

Crutchfield Customer Review (What's this?)

I have read the other reviews and I just don't understand them. The factory speakers on my 2010 F150 sounded much better than these. I am using the stock Sync head unit and these speakers just sound horrible. I have had them about 4 months now so they are definitely broken in, but they just sound like trash. There is little details to the highs and mids and the bass just washes out everything. I have tried turning down the bass all the way, but the upper ranges still don't sound clear. I drive an 2008 Chevy at work with one blown speaker and the one working speaker still sounds better than the 4 of these I put in my truck. Installation was a breeze, but I just feel like I threw my money away on these garbage speakers. I spoke with the advisor and specifically said I didn't want a bass heavy sound. I've tried satellite radio, terrestrial radio, CDs, input line and it is all the same. Just awful. I do not have a problem with Crutchfield - the people are nice and professional, but I just can't get over the feeling that these speakers are refurbs or defective junk.

Pros: None. Zero.

Cons: Awful sound. Muddy bass competing with flat highs. Just absolutely the worst sounding speakers.

Crutchfield Customer Review (What's this?)

great sounding speakers with a perfect fit in my ford F250 and with the included wiring harness adapters no need to splice anything,just plug in,stick em in the hole, and crank it up. Crutchfield delivers once again with fast delivery,packaging,and even the master sheet which was emailed to me before the speakers even arrived so I had time to check everything out about removing the door panels. it was perfect. install time was about 30 min. I am going to get another pair for behind the seats. thanks Crutchfield

Pros: quality built speakers with easy installation

Cons: no cons about speaker themselves but next time I will also get new speaker wire, factory wire in my truck is very thin and cheap better wire will improve the sound even more

They sound great, so much better than the factory speakers, easy install. Great information from Crutchfield on how to disassemble the door panels. I have always had Infinity speakers, both for a vehicle and home systems. Nice and clean sound, clarity is great, bass is good as long as you don't push them. I do not have external amp which may help the system. In any system, if you want bass your are going to feel, you need a sub, period. Well done Infinity as always.

Pros: Good clean, crisp highs, bass is tight.

Cons: None

The sound quality paired with Pioneer AVH-X3500BHS is pretty amazing. Did notice distortion at higher volumes with music with a lot of bass though. Overall I don't think you'll be dissatisfied with this purchase.

Second set of Infinity Reference speakers I've owned. As such I knew what kind of quality to expect from the product. Great mids and highs, bass could be slightly better, but short of having subs I don't know that I've had a set of speakers perform this well, and who can argue with a buy 1, get 1 price?

Pros: Great, smooth sound, pivoting tweeters, decent midbass

Cons: Low end response(easily corrected with a sub if you feel the need to have that kind of rumble

Awesome speakers. Picked up on Black Friday sale. Glad I did. Sounds way better than my old stock Ford speakers.

Pros: Sound great. Aimable tweeters. Fit great.

Great soundstage for the price

Written By BW, New Orleans, LA on Friday, December 13, 2013

Crutchfield Customer Review (What's this?)

These speakers surprised me by how well they performed, particularly for the price. They're not perfect, but they do a fantastic job of faithfully reproducing the intended sound.

The (not so) bad: At upper volumes there exists some distortion, particularly in the upper vocal range (picky ear). Lower frequencies normally found is lacking.

The good: Very clean, accurate sound, which allowed me to hear much more of the soundstage, with greater detail and fullness.

The notable: These 2-way speakers might not even need distinct tweeters. I've had a 6.1 channel setup with Polks and separate tweeters (+sub) for a year until this upgrade, and the sound was okay. These Infinity's do the job better hands down with just a 4.1 channel setup.

Also, tweeters have additional +/- 3 db settings to play around with. I have mine ON (4.1 rig), but I will probably disable that feature if I add Kappa tweeters because at present they sound distressed at louder volumes, and, with elevated upper frequency EQ settings you'll get a background hiss.

Sound is really fantastic for the price, particularly when paired with a powered subwoofer. Very pleased, would recommend.

Great speaker, great customer support!

Written By Jim S., Palm Coast, FL on Wednesday, December 11, 2013

Crutchfield Customer Review (What's this?)

I had a problem with one of the speakers not being glued properly to the speaker frame. Crutchfield was excellent and got out a new pair to me. The sound is fantastic! I'm using the stock Ford Nav/Shaker system. Note: as others here have noted as well, you have to cut off two metal tabs on the frame for it to fit.

Pros: Fantastic sound from the stock head unit. Great speakers for a great price!

Cons: They don't install themselves!

Written By S308, Trenton, NJ on Tuesday, November 05, 2013

Crutchfield Customer Review (What's this?)

These were used to upgrade Ford factory speakers which were poor at best. They were a nice drop-in upgrade for my Ford system with Sirius radio. The stock speakers sort of made Sirius radio a waste of money, now it will be much more enjoyable. The improvement in sound quality is just amazing. I enjoy a wide range of music like 50's, 60's, 70's, Rock, The Blues and Smooth Jazz. After testing it today I think I'll be enjoying the factory radio with my new speakers for a long time to come. These were a Crutchfield Support Rep recommendation.

Pros: Crutchfield provided the excellent support documentation and nice wiring harness adapters to make it the upgrade very easy to perform.

Cons: None

These are GREAT sounding speakers. The highs are crisp and clear, the bass is rich and full. I replaced the original factory Infinity's with these because of extensive research into every spec.

Replaced both front door speakers in my 2009 Ford Escape, which had the standard 4 speaker factory speakers. Could not tell much difference before and after, the speakers did not make a lot of difference (although they are slightly clearer than before).

Crutchfield Customer Review (What's this?)

SO, my wife's factory BOSE speakers decided to start rotting in her 2007 Mazda 3 Hatchback so I was on a quest to fine the best ones. Now, the BOSE factory system does have an external amp, a tweeter in the door, and a small subwoofer, so I knew my work was cut out for me.

I had to: a) find 2 ohm speakers (these are 3 ohm, FYI) to replace the door speakers so the impedance load wouldn't screw anything up and I could draw enough power from the amp b) make sure they fit without needing extra brackets, etc etc c) make sure there wasn't going to be too many "highs" since we now how a door tweeter AND the tweeter on this.

A and B, easy to research. C? Not so much, because i couldn't find any info on whether the bose system uses a crossover on the midrange speakers.

I am also a person to ALWAYS listen to speakers before I buy them. ALWAYS. These I did not, only read the reviews.


Bottom line, buy these beasts. The audio replacing the factory BOSE is AMAZING. Absolutely amazing. I was worried the amp wouldn't be able to power them enough, but turning the system all the way up causes distortion on the rest of the system before these speakers. And they harmonize WONDERFULLY with the rest of the speakers. You can hear things on these speakers we never heard in songs before, like subtle little tones or guitar riffs. We like heavy metal, acoustic, hard rock and all of it is VERY clear.

Anyway, love the speakers. Simple as that.

Good clean sound

Replaced factory speakers in daughter's '04 Ford Explorer Sport Trac. Powered with Pioneer AVH-X2500BT and Alpine MRP-F300. Great end results with a very pleased 18 year-old who listens to classic rock, hip hop and pop. Paired with a Sound Ordnance B8-PTD to handle the low end. The system work well together and the directional tweeters in the Infinitys make a difference. Opted not to use the high end boost in the speaker.

Pros: Sound quality, ease of install, directionally adjustable tweeter

Cons: None

Infinity Reference X 8602cfx

Written By ATY, Southern MD on Wednesday, May 15, 2013

INCREDIBLE!!!!! Bought these to replace the OEM speakers in my 2012 Ford F-150 Supercab. The OEM speakers were just awful. I am extremely impressed with these speakers. As someone wrote in another review they sound much better if you select the +3db option which is a nice touch. They have plenty of good clean, clear sound with plenty of punch for a 6x8. Install time was about 40 minutes total and was very simple, even for the first time installer. I have these mated with a 10" MTX Loaded Thunderform. I also installed a remote gain adjustment to select how much thump I'm in the mood for. At a later date, I will be installing these in the rear doors as well. The sound is that good!!! After that I will be replacing the tweeters with FOCAL. To really hear the clarity of the Infinities, music from an ipod or stick is best. FM also sounds much better, but lacks the clean digital clarity. You will not have any regrets with this product.

Pros: The Audiophile in me lives again. GREAT super clean, distortion free sound.

Cons: Absolutely none.

Infinity speakers will always set the mark of excellence.

Crutchfield Customer Review (What's this?)

Replaced the horrible stock speakers in my 2013 F150 STX with these speakers. I can't express how much of an improvement these made in the otherwise stock sound system. I had no problem whatsoever dropping these in with no mods of any kind. The adapters for the Ford wiring harness did not fit tight on the speaker lugs so I soldered them to the speakers. Probably a good idea regardless. Then I placed plastic tie wraps around the wires and speakers. Anyway, These speakers sound GREAT! Cristal clear. The highs are sharp and crisp. The mid-range is separate and highly articulate. The bass is nice and tight. You will not get a lot of bass with these (or any 6x8), but what is there is well defined an responsive. Additionally the tweeters are adjustable with two settings. I found that the -3db cut some harshness out of what some recordings have and better defined the mid-range. But that is subjective and that is why the are switchable. These speakers are also very efficient. Clear at low volumes and even better when driven. Even with the stock head. Overall these speakers sound great and are a huge improvement over the original equipment. I highly recommend them.

Pros: Adjustable tweeter. Drops right in with no modifications. Great sounding. Tight bass.

Cons: None

These Speakers sound so much better than the original. Vocals are much crisper and the bass response is exceptional even on the stock radio. The sound got better when I did change the radio though.

Pros: Very close t o direct drop in as you can get from the aftermarket.

Cons: None

Great speakers, if you plan on adding a sub. The mids and highs are very clean, but they definitely lack bass. I hooked mine up to an old 50 watt alpine that I had and they sounded very clean, but not as much of that deep rich bass, my stock speakers had much more. Overall great quality though. After I installed a set of 10 in. infiniti reference subs in back the system was perfect.

Pros: Great mids and highs crisp sound great quality

Cons: Lacks bass

Crutchfield Customer Review (What's this?)

After installing these speakers for both front and back speakers in my F350, I can say I am very pleased with the quality and sound these speakers produce. The only flaw was Crutchfields instructions, it was minor, the socket size to remove speakers and door panel was different than what the instruction showed.

Pros: Quality/Construction and sound great

Cons: None so far

Crutchfield Customer Review (What's this?)

Installed in my 2009 F150 Super Crew Cab, and thought the mids and highs were very good, but they lacked even the amount of bass present in the stock speakers. I wanted to install something where I could just replace the speakers without adding amps or subs. I returned these to Crutchfield, and bought Kicker KS68 speakers instead. I was much happier with the Kickers. The Infinity speakers would be a great choice for someone who is looking to add subs later on. I was very pleased with the clarity, but wanted a little more low end.

Pros: Clear Mids and Highs

Cons: Lacked Bass on stock head unit power

Pros: Simple Install, Fast, Awesome Sound

Cons: None

Written By DougVK, California on Friday, January 18, 2013

Crutchfield Customer Review (What's this?)

I installed these in a 2012 Escape with Premium sound - replaced all 4 speakers (front and rear doors). The overall sound is better, but the improvement isn't as dramatic as you might expect. They are much better than the single-cone rears and somewhat better than the 2-way front speakers that come with the car. However, there are a couple of issues I discovered: 1 - The Infinities are not as efficient as the stock speakers. That's a problem because the Ford "Premium" system includes a subwoofer and (as far as I can tell) there's no way to adjust the level of the sub. So you need to turn down the bass at the head unit to stop the booming in the back, which is not ideal and probably the reason these don't sound as rich as I was expecting. 2 - After a few weeks, my speakers started cutting in and out. After some trial and error I discovered that the problem was the wiring harness adapters that Crutchfield supplies. Although they were correctly connected to the Ford harnesses, the electrical connections were not solid. I cut the connectors off and spliced the wires directly and they work fine now. Strangely, this only affected the front speakers; maybe the connectors were slightly out of spec.

Pros: Very clean sound - extended highs. Great build quality.

Cons: May not be best choice for Fords with Subwoofer - recommend finding more efficient speaker; Connectors did not make reliable electrical connection.

Great sounding speakers, 100% improvement over the factory speakers Ford Installs. Be advised if your NAV system includes a tweeter in the door panel, it will need to be disconnected to use, with the great sounds produced from these speakers there is no need for the factory tweeter.

Pros: Great clear and powerful sound

Cons: None

Crutchfield Customer Review (What's this?)

Great speakers and a great price. I am very happy with the sound quality of these speakers. I am running these as rear speakers through an Alpine KTP 445U amp off a Kenwood deck. Front speakers are a pair of Rockford Fosgate Prime R1682. Comparing the two I am more impressed with the sound of the Infinities over the Fosgates. The Fosgates tend to distort at higher volume long before the Infinities. After adding the little Alpine amp these speakers really came to life. Crisp highs and great sounding mids. I'm using these strickly for my highs and mids as I'm also running a Sound Ordnance B-8PT powered sub that I must say, I'm also very impressed with. All this is in an 05 F-250. It's not going to rock the neighborhood but it will definitely deaden any noise or voices that may be along for the ride with you.

Pros: All good so far!

Cons: none

Good speaker for the money

Written By JonathanG, College Station,TX on Thursday, November 29, 2012

Crutchfield Customer Review (What's this?)

Installed these in my 02 mustang not long after installing a Pioneer head unit. The install was a breeze thanks to the detailed instructions that Crutchfield provides. Seemed to get better highs out of these speakers, but as far as bass I cant notice much of a difference from what i heard i would. Maybe i am just not fine tuning my head unit to this right, very possible. The only downfall i had with these is that the spade terminal on them are very brittle and i almost broke one off when trying to plug in my harnesss. also had to use some nuts and bolts when reintalling since the factory screws were not getting these speakers snug.

Pros: Good quality, good sound, good price

Cons: brittle spade terminals

Very Happy with these in my 2012 Ford F150 XLT

Written By Rich, Omaha, NE on Thursday, November 22, 2012

Crutchfield Customer Review (What's this?)

Replaced garbage factory stock speakers on F150 with stock H/U (not Sony), no AMP, no Sub. The speakers were easy to install. Mounts with screws that held the factory speakers in....this is a big deal as I had to return a nice pair of Pioneer TS-D6802R speakers that would not mount with the rather large pan-head factory screw because of the very limiting plastic bezel around the speaker. If you use a different screw, as I tried, you strip to plastic ford fasteners because a standard 8 x1" screw that comes with most aftermarket speakers has a thread that is too tight.

Pros: Sound quality, even with weak factory H/U.

Cons: Little tough to get the wire harness connections the speaker leads...but patience prevailed.

I bought a 2011 ford escape new last summer with fords "premium" sound which is a joke. After having the car for a few months the speakers started rattling as if they were blown already. Ford would not replace them because they said there wasn't anything wrong. I bought these speakers and it took care of the rattling and also gave a much better sound. I only replaced the front speakers but after hearing how good they sound I will be buying them for the back also.

Pros: Great sound, high quality

I'm a longtime customer of Crutchfield and these aren't my first Infinity speakers. I hadn't really made up my mind about new speakers but when these went on sale I went ahead and bit. Glad I did. Even without a deck upgrade the sound quality is so much better. As always you get everything you need and the install was very easy. I put these in a Mazda 4 door pickup and they fit perfectly.

Pros: Great price, great clear sound and easy install.

Speakers took less than an hour to install on my Mazda 3 hatchback. The car specific master sheet and included wire harness allowed me to install the speaker using only the included parts. The sound is much improved but I feel an amplifier would be needed to reach the speakers true potential.

I installed these speakers in the rear of my 98 F150. They are powered by by a 40 watt external amp ran off my JVC KD-AHD59 Arsenal HU. I had no problems installing these. The included instructions were very helpful. I opted not to run a sub woofer and have no regrets. The bass and highs from these speakers are very impressive. Ifinity hit it out of the ball park with these speakers.

Pros: Probably the best sound you are going to get for the money.

Cons: I have a hard time not really cranking up the volume.

Great upgrade to stock speakers

Written By JohnJ, Indianapolis, IN on Tuesday, July 10, 2012

Crutchfield Customer Review (What's this?)

Purchased these speakers to upgrade the factory units in my son's 2002 Taurus. These are a vast improvement over the stock speakers - much better bass response and overall sound. Installation was easy in both doors and the rear deck, with one exception. Both door speakers caused an interference with the power window mechanism which would not allow the windows to go all the way down. We removed the speakers and added shims to the mounting tabs along with a thicker gasket around the basket. All is good now - no interference and much improved sound quality.

Great upgrade to stock system

Written By Andrew, Denver on Monday, June 18, 2012

Crutchfield Customer Review (What's this?)

Installed in a 2003 Mountaineer with the "Premium" audiophile package. Off the factory head unit and without an amp, these speakers were still night & day better than the stock "premium" speakers. Great clarity and just sound better as they get louder. High & mids are great, and the bass is surprisingly good. Took out the factory amp/sub for a couple days to replace the sub, and even without the sub in the car (just the new infinitys) I still had good full sound. These speakers are a no-brainer upgrade to any stock Ford system that takes 6x8's.

Pros: Easy install, sound great in stock system without other aftermarket components.

Cons: None

Product is just as advertised. Easy installation in an 06 f150 supercab. Has turntable tweeter and 3 db gain button to get the most out of your highs. Would do well with a "system" or just by themselves with a factory HU. As a matter of fact, makes the lights dim a little on my HU... If that gives you an idea of the output. Can't go wrong.. Affordable quality.

Sound great. Very nice highs, clear mids, and decent base for a 6x8. They fit perfectly in my 2005 F150. I did have to clip off the extra metal install holes for the front pair but that was very easy. Back pair just fit right in. Only took me about an hour and a half to install both pair. Well worth the price, especially the sale price of buy one pair get one half off. They sound way better than the factory speakers. Be sure to push the button on the tweeter to get a better high range if needed.

Pros: Much better than factory sound. Easy install. Good price.
