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 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.

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 recently installed these in all four doors of an F150 Supercrew, and they are a huge improvement over the factory speakers...although that's not a huge hurdle for any aftermarket speaker, given the cheap speakers most stock stereos employ. I can only compare these to two previous installs I did on other cars, one with Polk Audio 2-ways and one with Alpine Type-Rs. I would rate these as substantially better than the Polks, and on par with the Type-Rs. The Type-Rs probably had better high-range and tighter mid-range response, but these Infinitys put out better low-range sound that the Alpines did. I still supplement with a stout subwoofer, but the sub was an absolute necessity with the Alpines, whereas it's more of a bonus with these Kappas.

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.

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

Best speakers for clarity in your truck.

These speakers sound incredibly clear and are non-fatiguing. I was looking to upgrade the speakers in my F-150 and chose two pairs of these Infinity's and although they were a little more than what I wanted to pay, they were totally worth it. Tons of detail, the highs aren't piercing or painful and they offer a deep soundstage that really sound great in my truck. I originally hooked them up with no amp and there was a small gain over the factory setup but once I added a 4-channel amp these speakers really sing. A did a lot of research as well as speak to crutch field reps several times and ended up with these. I was not disappointed once I amp'd them. If I was going with no amp I would go for cheaper speakers cause there's just not enough difference for the 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.

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
