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

I have these installed in my son's Ford F250's front doors running off a Stinger 4 channel amp and they sound crisp and clear even at higher volumes. I have always been a fan of Infinity and when I saw these could handle the power of the amp my son bought I was like "that will do Donkey, that'll do!" I like that these have screw down terminals for connecting speaker wires since we ran 12 AWG to the doors for maximum power handling. Overall I am very happy with my purchase.

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.

I purchased 2 sets of these speakers, a 4555a amp and a kappa 12 inch sub to install in a Masada 3. Overall very pleased with the set up except that only 3 out of 4 speakers worked. I’ve tested the speaker and I just can’t get it to work but still very please with system just need to get the 4th one replaced

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 - 10/5/2019This 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 rmsat 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.

Sounded great when they worked. Had no more than 200 watts combined (100 watts per speaker) driving these and the components around the connectors melted ruined the speakers. As soon as it happened I didn't make any changes to my amplifier and checked the wattage output when I got home to make sure I wasn't overpowering them. I tried to contact their cutomer support and did get a response.... That they would pass the word on and see if they would honor a warranty replacement. Didn't receive a response back. A week later I emailed them again. No response. Just gave up with that because I knew it was gonna be a bigger headache.

I replaced the front door speakers in my Ford Flex. The original ones served as woofers in the system. The Infinitys are coaxial which adds an overall fullness to the sound up front. They're very efficient so the bass has more impact. The silicone baffles and sound deadening mat also helped. The entire package really improved the front seat listening experience.

i installed these to replace the rear speakers in my 1998 ford ranger regular cab.After adjusting the sound on my pioneer head unit the sound was amazing , loud and crystal clear. I highly recommend these speakers.

It fits and works really good A++
