About the Infinity Kappa Perfect 300m
The Perfect companion
The Perfect companion
Turn your Infinity Kappa Perfect 2-way component system into a 3-way system with the addition of these Kappa Perfect 300m 3-1/2" midrange speakers. Infinity uses a carbon fiber cone that weighs less than traditional materials, so you don't need a ton of power to drive this speaker, but the oversized voice coil certainly allows for awesome power-handling if you're driving this system with an amp. Infinity's Plus One+ woofer technology extends the cone right up to the edge of the basket, giving you more surface area than with most comparable speakers. A bigger cone allows this speaker to cover effectively down to 150 Hz.
Uber-Infinity
Infinity's flagship Kappa Perfect Series speakers look so good and feel so solidly built that it's a shame you probably won't lay your eyes on them again after they're installed, but it's a small price to pay to experience unrivaled audio in your vehicle. This speaker is a heart-and-soul Infinity creation, utilizing the very best technology and materials available to their engineers.
Grilles are not included; the factory grilles should be suitable for most applications.

These things are built like tanks! Great sound. Like others I had to cut off 1 mounting ear on the speaker to fit the dash of my Challenger. Worth the money.

2017 Ram 1500
I ordered two pairs of these, speakers, the instructions were a bit grey, but the tech line filled in the gaps.....:), The speakers are awesome, and the reason the install instruction's were lacking, is because you have threaded adapt for the speakers, so if the positive and negative wire colors, were identified, it would have really helped.

Perfect Midrange - Jeep Renegade
Caleb from Paducah, KY on 12/3/2018
Amazing crisp sound produced by these midrange speakers. Used these as replacement in Jeep Renegade for the front dash speakers. Definitely recommend.
Pros: Very happy with the sound produced by these midrange speakers. They came with a set of wiring harnesses, which was helpful.
Cons: For the Jeep Renegade, it was a tight fit, but not too terribly difficult to install. If the four metal tabs were just ever so slightly thinner, it would be a piece of cake to swap out. But very much worth the 15 or so minutes to swap out.

These replaced a pair of Focal 3.5"s. I have them band passed 450-3500 and EQ'd via JL Fix D8 and they sound great - not bright at all, good warm sound, very detailed. Very solidly built as well, and easy wire connections.
Pros: Solidly built, not too bright, very detailed and clear
Cons: Had to dremel out the mounting hole 1/20" to fit my '15 Mustang. ??

Nicholas from Canonsburg, PA on 3/16/2018
2014 Chevrolet Camaro
The good: - These speakers are incredibly efficient. They're running in my car with a set of Morel Tempo 602s in the front, and even with the gain turned down on these they were still overpowering the Morels at medium volumes. I had to manually adjust further - They are extremely loud for such small speakers, and sound quality is excellent. These make excellent rear fills for when you want your rear seat passengers to hear a clear high end. The Bad: - They are extremely "bright". After 5-10 minutes of listening to them I'm already "tired". I much prefer the smooth high end of the Morels, and my system sounded much better once I got these playing at a fraction of the volume of the fronts. - They seem to have some weird resonance; certain frequencies come across far too strong, and even at below the rated power handling I thought I could hear clipping (again, only at specific frequencies). The Verdict: For the tiny size Infinity did an incredible job with these guys. But I was hoping for something a little smoother. And that weird resonance really gives me pause on these. I'd definitely recommend listening to a pair before purchasing.
Pros: Very Efficient Great sound quality and clarity
Cons: Very "bright" Odd response on certain frequencies

These speakers are LOOOOOOOOOUD, when you amplify them! I installed these in my 2016 Chrysler 300c with 75 watts rms going to each speaker and they siiiiiing! The only modification that I had to make, was breaking off two of the four tabs for each speaker to fit, which was a piece of cake! Thank you Crutchfield and Infinity!

Clean powerful sound
Dan from Algonquin, IL on 2/2/2018
2006 Jeep Grand Cherokee
Replaced the factory Boston Acoustics to finish of my system with these in the dash of my Jeep Grand Cherokee and the quality of the sound improved vastly. Cleaner sound with more punch, these paired nicely with the JBL 6x9 & 6 1/2 and Kicker sub. I did have to cut off two of the corners which are metal to fit but it was easy with a cut-off wheel.
Pros: Clean and clear sound, well built
Cons: Have to modify the speaker to actually fit

Great sound, but cutting is required for 2014 Ram dash
John from Albuquerque, NM on 12/11/2017
2014 Ram 1500
Sounds great but installation in 2014 Ram 1500 DOES require some cutting. I had to notch the inner edge of both factory speaker mounts, as well as remove the outer back leg of the factory grill. These two modifications were directly attributed to the fact that the speaker is in a cast metal frame with 4 mounting ears, the factory enclosure only accommodates 2 ears. Additionally, once you have cut and are ready to place the speaker, make sure your wiring is finalized as the speaker will seat quite firmly (wedged) into the enclosure and you might have difficulty getting it back out. It seats so firmly in fact, mounting screws are not needed.
Pros: Awesome sound, got rid of high end popping I had with JBL and Kicker dash speakers.
Cons: Cutting required for dash install 2014 Ram

Sound is excellent and clean
Matt from Prescott, AZ on 12/3/2017
2015 Jeep Renegade
I start by saying the sound is amazing. I installed these in my 2015 Jeep Renegade Latitude (dash location). My Jeep has the six speaker setup with no amplifier. I'm not sure if I'll amplify or not but wanted to be prepared just in case. I also did the front doors with the 5 1/4 Polk Audio which I've used before. Installation was somewhat tedious with these Infinity Kappa's. For the Renegade, these pop up on the Crutchfield search as the only option which was disappointing as there are other 3 1/2" speakers on the market. Regardless, I ordered these. Out of the box I could tell these would present a challenge as the speaker surround and tabs for screw down are hefty and although you need only two, these have four and cannot be trimmed off (a grinder might do the trick but alas, I did not have one). I had to manipulate these into place with considerable effort. Also the supplied wiring harness fits the factory but the actual speaker connectors need to be cut off as the wires are screwed directly into the speaker. I did get them in and was able to replace the factory grills. I give the sound 5 stars but install 3. One other criticism I have with regard to the vehicle specific search and in particular the Renegade is the search says you can put 5 1/4" or 6 1/2" in the rear doors (I have not changed out yet) but be advised, the front and rear doors both have factory 6x9" speakers so keep this in mind when you're shopping as you have more options than what's listed.
Pros: Great Sound from a small package
Cons: Install in the Jeep Renegade is not as easy as directions say but possible.

Great sound
Marc from Florida on 7/5/2017
2010 Dodge Ram 1500
Well, I needed midrange help for a 3-way active front set up.. I paired these with boston acoustics pro60 SE woofers and tweeters.. I have them bandpassed at 5000hz to 500hz @ 24db xover.. 100 watts rms a piece running to them, and they sing in the stock dash location of my 2010 Dodge Ram.. the only negative was that it was a very tight fit (had to trim some dash + two of the speaker brackrt tabs off), however, the increase in vocal clarity, strength, and sound stage height, was well worth the mod.. I should have put midrange speakers instead of tweeters in the dash way earlier than I did.. A+ to these speakers..
Pros: Great sound, power handling, sturdy construction..
Cons: Extremely tight fit.. (Not really the speakers problem)..

Thanks to the online chat team for the help. Fits great in a 2015 Renegade. I suggest you cut one of the 4 mounting tabs off. Easier to install. And a better fit. Next I'll be replacing the front side speakers. Have them in my cart already.
Pros: I was amazed on how great they sound. Disappointed with the factory speakers I pulled out. Very cheap.
Cons: None really. Just cut off one of the 4 mounting tabs.

Infinity Kappa Perfect 300m
Mike from Virginia Beach, VA on 1/10/2017
2016 Jeep Renegade
Really good speakers. I placed these in the dash of my 2016 Renegade. As I was replacing all 6 of the speakers, I did these first since they were the easiest to get to. After swapping them for the factory speakers, they were louder and better than the remaining factory door speakers. While these speakers "fit" in the dash, you need to either cut the dash bracket that holds the speaker OR be very patient and work it into place. I was able to get it at an angle and kind of force it into its spot. The only bad thing is that the factory speaker is 2 holes to hold it in and the Kappa is 4. So that makes 1 bracket stick out and gets a little in the way when you replace your speaker grill. 4 of the clips in the grill will snap back in, but the rear one does not. I will leave it like this for now (it is not too noticeable), but may eventually go back in and file down/saw out the part of the dash that is in the way.
Pros: Good sound.
Cons: It is a tight squeeze in the Renegade.

More details on the Infinity Kappa Perfect 300m
Product Research
Features
Midrange: These drivers are midrange, designed for use with the Kappa Perfect 500, 600, or 900 2-way component sets (all sold separately). The crossovers included with the component sets can be set to 3-way for use with these Kappa Perfect 300M midrange.
Mounting: Unlike typical 3-1/2" speakers, the 300M has four mounting tabs. (Most 3-1/2s have two.) When mounting in many factory speaker locations, two of the tabs will need to be removed.
Plus One Cones: The Plus One midrange cones offer more surface area than other speakers that fit in the same size opening. This is accomplished by using a new basket design and hi-roll surround. The result is greater bass output and a significant increase in efficiency.
Terminals: The wire terminals are set screws that will accept up to 14 gauge bare wire.
