I have 3 trucks with all kicker speakers good product
Good set of speakers, definitely raise some hell especially when you see how tiny they’re when you open the box. I have these a the kicker 6 3/4 in both of my trucks, even did the same set in my cousins truck. Using these series of speakers in 3 trucks tells you they’re good value for the money, an everyone comments how good my trucks sound when they hear it.

Great set of speakers!
I purchased these 6x9 KS Series Kickers for my 2018 Silverado and the included mounting hardware fits perfectly. The speakers sound great. Solid low frequency bass without distortion. The highs are very clear without sounding tinny or shrill. Overall, very happy with them. Also purchased the matching 2.75" mid ranges for the dash. Again, mounting hardware for perfectly. I have an aftermarket stereo that has an EQ with I aware about 30 bands. With the stock dash speakers, the top 10 bands did nothing, literally no difference. After installing these kickers, every single band now has a perceivable impact. So these speakers are clearly much better quality over factory (obviously), but I was really impressed that they handled all of the higher frequency bands so well. Really pleased with them.

Great for Gbody
I got these for my 1985 Oldsmobile Cutlass and I absolutely love them. They are crisp, clear, and can handle my heavy music taste. They slide right on the oem speaker brackets with no modifications and come with spliced connectors to make installation easy. I've had them for a while and still sound great blasting some metal. Would definitely get these for another vehicle.

This rock and pound! A trusty solution well made
I would give these particular KS kicker speakers 5 stars but it arrived with 2 100 microfarad capacitors that are not clear for the user to connect to the speaker and or if you should use them considering what they actually do. In my case I didn’t use them because of the amp used is rated for 4ohm and a crossover that is able to control its received frequency range. If you wanted to wire them in parallel to a single channel, then you would need to use these capacitors inline on the positive lead to each speaker thus making it operate at a 2ohm load. The mounting is perfect for many vehicles. Comes with 2 GM/Mopar brackets 2 Chrysler/Jeep brackets 2 Toyota/Subaru brackets Two 11" Lengths of speaker wire (tinned wire on one end and quick slides on the other), very important for the long run and if you live where there is any weather. Two 100 microfarad capacitors not necessary for me to use. 4 Red plastic wire caps- good quality but lacking my favorite a conductive cream called Ox-guard, when using be sure to not short out two terminals as it increases conductivity but works well in this case of crimping wires. I use it almost daily. Four 1-1/8" Screws, threw in the pile of unused screws. Quick-Start guide (English/ Spanish/ German/ French) didn’t fully help.. hope this helps and you try these speakers. I have all kinds of different speakers and so many vehicles that I’ve been building for the last 30+ years and I gotta say kicker is a brand I always come back to. For this particular client of mine they have blown the competitors away, I literally just finished one of the best soundings systems that didn’t break the bank using 11 KS speakers in a 2022 Chevy Equinox. Brackets were perfect i just reused the hardware from the vehicle. For mounting always consider considering sound deadening mat and or sound baffles and acoustic phone. It’s a cheap way to really improve the quality of your sound.

Speakers that turn my truck into a concert hall (and my nonexistent Alaskan neighbors into enemies)
The Kicker 51KSC69304 KS-Series 6x9 3 way speakers are absolutely insane. I put them in my truck, hit play, and suddenly my backseat feels like front row at a rock festival except with more potholes, snow, and the smell of old snacks. Bass that rattles your teeth, mids that make my singing sound semi-professional, and highs so crisp I can hear my GPS shouting at me in stereo clarity. Honestly, I didn’t know speakers could feel this alive I half expect my truck to start headbanging on its own. Durable, powerful, and ridiculously fun, these speakers make every drive through the Alaskan wilderness feel like an epic road trip montage. And if I had neighbors up here, they’d probably call the cops but honestly, it’s just me, the moose, and the mountains, so I crank it as loud as I want. Absolute chaos in the best way.

Kicker does it again - fantastic budget components
Kicker does it again. I added these to the doors of my small pickup to replace some low budget trash that had been installed by the previous owner. They are wired through an amplifier capable of pushing 300 watts per channel so I reduced the gain to prevent over-powering these speakers. At first listen it sounded like I had added a small subwoofer to the vehicle. Sound remained clear at high volume with no distortion heard. I have crossovers / low pass filters set through the amp to avoid sending low frequencies these speakers can’t handle to them. The sound is quite impressive for the price point. Kicker has shown once again that they are capable of producing a good product at an affordable price point. Install is straightforward - if you’ve installed speakers before; these are no different - Positive wire, negative wire. Don’t mix them up and you’ll be good to go. Overall I highly recommend these speakers if you’re looking for good sound without breaking the bank.

Nice speakers just my luck one did not work.
I ordered 2 pairs and out of the 4 speakers total, only 1 was defective. I don't believe it was the shippers fault just luck of the draw. Returned defective set and kept the other.

Beautiful upgrade over my very old and crusty OEM speakers in my 2004 Honda Element EX. The sound is rich, warm, and well-balanced, just the way I like it, perfect for classical music, jazz, and crooners, which I listen to most. They also handle electronic music surprisingly well, and the bass is solid! I spent weeks searching for the right speakers, and these definitely do a fantastic job. At this price point, it’s hard to find better! Highly recommend!

2018年式マツダCX-5 BOSE仕様車のセンタースピーカー交換にこちらを使用しました。 音の輪郭がハッキリ違います。そのおかげで前方定位感も良くなりました。 外国産スピーカーは初めてでしたがなかなか繊細な音が出て大変満足でした。

Suenan mejor que las bocinas de serie, se las puse a un Nissan Versa 2016 en la parte delantera y quedaron muy bien, tienen bajos muy decentes, tardo un poco en llegar el producto pero todo excelente con el empaquetado, sin problemas.

La calidad de materiales es buena y el audio cumple bien para el precio, el kit de instalación y adaptadores esta muy bien. En cuestión de audio no es lo mejor del mercado pero cumplen bien.
