Review: Great speakers, Fit like 6x8s which actualy helps sound - 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.
Review: Great speakers, don't forget to buy adapters to the factory wiring. - Love these, sound great and were a good value! I recommend buying the factory wiring adapters here on desertcart, it made this install super easy! I know you don't "have to have" the adapters, but it was so nice!

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!

### ⭐⭐⭐⭐⭐ replaced stock speakers-07 f150
*by S***Y on September 28, 2018*

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.
