Infinity Kappa 6X8"/5X7" 300 Watts Max (100 Watts RMS) 2-Way Coaxial Car Audio Stereo Multi Element Speakers with UniPivot Tweeters with Oversized Voice Coils - Pair Bundled with Alphasonik Earbuds

The Infinity Kappa 6x8"/5x7" coaxial speakers sound excellent, exactly as you’d expect from the Kappa line. Sound quality is the standout here—clear highs, strong mids, and overall very clean output even at higher volumes. They get loud without sounding harsh or distorted, and they handle power well. For coaxials, they deliver impressive performance and noticeably improve clarity over factory speakers. Build quality is solid. The materials feel high-end, and the speakers have the durability and fit-and-finish you’d expect from Infinity. Once installed and powered properly, they really shine and bring the system to life. One important thing to note is fitment. While these are advertised as 6x8"/5x7", they fit like true 6x8s, not 5x7s. If your vehicle is set up specifically for 5x7 speakers, you’ll likely need adapters or minor modification. They are not a true drop-in 5x7 fit, so that’s something buyers should be aware of before ordering. That aside, performance makes it worth it. They sound amazing, with clean detail and strong output, and they absolutely live up to the reputation of the Infinity Kappa brand and line. If you’re looking for high-quality 6x8 speakers and care more about sound than strict plug-and-play fitment, these are an excellent choice.

Love these, sound great and were a good value! I recommend buying the factory wiring adapters here on Amazon, it made this install super easy! I know you don't "have to have" the adapters, but it was so nice!

So, after a USPS delivery mishap that amazon made right, I finally got my delivery. These are really nice. I read a lot of reviews before choosing these to replace the stock speakers in my 2007 F150 supercrew. I already had some Kicker KS for the back doors, so these went in the front. Install was...not complicated but took a litte extra work. I had to dremel off some of the mounting brackets that stick out from these kappas or they would not fit into the space in the front doors. Kind of a pain. Oh well, no biggie. Also, I ordered the wiring harness for these, but because the kappa are screw type connections, I had to strip the end of the wiring harness to make it work with these speakers. Again, not a huge deal. Once in, they sound great, a major improvement over the stock speakers. I am currently using the stock radio but that will be upgraded next and I assume these speakers will only sound better. Everything I researched said to get an amp and sub with these. I won't lie, they do sound really decent for not having an amp or sub, but if you really want to rock out, you can just tell these things are screaming to have more power from an amp that my stock radio can handle. If you don't want all that, these are still really great solid speakers, you will not be disappointed because they are still way better than stock. I may swap out the kickers in the back with these as well . I haven't decided. Over all, I am extremely satisfied with this purchase. I don't think you can do any better for just simply swapping the stock speakers out.

Nice speakers that handle some power without popping off.Great sound and price

After a solid year of use they are still going strong. Have been running them on 150 watts RMS for months now. On Deck power (~18 watts RMS) with tweeter boost circuit off they sound pretty nice and smooth. Once on a dedicated amp they are way too bright however. Had to turn boost circuit off (it is not actually a boost circuit, it is a -3db filter). Still very good all around sound and do surprisingly well down to about 40 Hz.

The Infinity kappas proved to be a good decision on deciding which 6'8 door speakers to buy. It was a hard struggle between alpine and kappas. Both had the specs I needed but the kappas only won because of the 2ohms power handling. Very pleased with the purchase and will purchase again if need be. 5 stars. Update - 10/5/2019 This update is inform anybody wondering about the true performance of these infinity kappa speakers. i bought the kappas over JBL, Alpine, Skar, Rockford, kicker, and any other brand that sold 6x8 speakers. i did this based on specs alone but the audio quality of the product was riding on just a gut feeling. It has been about 4 years since my first purchase and let me tell you the audio quality ended up over shadowing the reasons why i chose the infinity kappas in the first place. The specs are just a side dish, the quality of the music production is the main mean. i highly recommend these speakers to any music lover who loves true audio quality in their car and who is not trying to shake everything from here to the airport. Well here i am again buying another set of the Infinity KAPPA 682.11cf speakers i could had bought the newer version but these right here are special. the only infinity kappa 6x8 speaker that is 100 watts rms at 2ohms and a sensitivity rating of 94dbs. the newer version is only 60 watts rms, that cant work for me. The next best option would be the JBL GTO Stadium 6x8 speakers when i absolutely cannot find these infinity kappa speakers anymore.

Definitely are a improvement from stock even with a amp or sub they are very clear and sound great

Had them Installed on my 2013 ford f150 with an amp that ran 80 watts rms to each speaker. The shop that was installing them then informed me that the speakers sounded like they were blown. They said no smoke or nothing came out of them. Went to look at them my self, and sure enough no burning smell nor was there any blackened voice coil. Seeing as I was short on time I had them put a set they carry. A return will be attempted but I’m not sure if they will allow as it’s a speaker and sometimes they say it’s user error

In a word. Impressive! Only being driven by a 50W head unit currently & still sound amazing. An amp will only improve them.

If you want sound quality speakers get these... I've ran a few pioneers in the past and can say that these kappas are different and surpases pioneer when the volume increases,once my volume knob goes to 25/35 on my kenwood head unit my ear bleeds that's how loud they get for real lol.The bass is ok and punchy but not great like the pioneer D-SERIES TS-D68f give you some lows feeling like you got a mini sub but that thing was missing some mids and highs and was focus on bass .You will only hear the difference once you add an aftermarket 4 channel amp to give these speakers the power they need since these are rated at 100 watts (Rms). Keep in mind that aftermarket Head units like kenwood/pioneer etc usually give about 22 clean watts each before distorting so once you give them the 100 watts you'll hear some notes in songs you've never heard before

Excellent sound quality

It's an absolute banging speaker. You want a club in your car? These are it. Can't see me? You can hear me dw. Crashing out with these speakers

Awesome product ... Best quality ... Awesome clear sound ... Buy them with confidence !!! A+++
