The 4" factory speakers in my LC76 Land Cruiser were murky and lacked bass. These KIckers bolted in directly. They include 4 mounting tabs. My installation only required two and the remaining two were easily removed with pliers. The sound is noticeably more clear. I am getting more volume. While bass remains limited as is to be expected from a 4" speaker, it is more controlled and crisp. Very oleased with the swap. Recommended.

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.

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.

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.

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.

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.
