    • Fit perfect in my 1998 GMC Yukon
Model: 51KSC41004
Took me awhile to find out who sold this size speaker. Kinda an odd size nowadays, but I wanted the best quality. And these are one of the best speaker brands in today’s market. You won’t be disappointed at all. Very easy to install, professional quality and excellent sound. Definitely worth the money. ... show more

    • Great bolt in replacement speakers
Model: 51KSC404
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. ... show more

Used these to replace the factory speakers in my 26 Bronco. Fit perfect and night and day difference in sound. No amp need, but I would recommend. Big difference in max volume level.

This is a fantastic speaker. I have a 2025 Subaru Crosstrek Premium, and I've built and tuned my entire sound system from scratch. These replaced my Kicker CS 3.5 2 way coax, because I was tired of the phase issues of having a tweeter mounted on the pole of the midrange woofer 3.5. The plastic and PEI of the CS also just had a very fatiguing metallic ring. These new Kickers were a great compromise, because I didn't want a coaxial in the dash, and I also wanted something more capable than just a plain midrange. I run these at 30W RMS, and they run alongside my doors, which are Hertz Cento 165 L, which also have paper cones. I used my DSP to adjust the EQ on these to be more warm and less fatiguing, and wow, these are amazing. I boosted some of the highs to give a bit more shimmer before they have a hard roll off. I don't know if I would enjoy these if I didn't have a DSP, so that's something to keep in mind for potential buyers. I personally prefer a warm sound signature but if you like bright, I'm sure you'll love them. I have them band passed from 400Hz-20kHz, using LR24 slopes on both top and bottom. I love these speakers, the detail is incredible. It's no Hertz Mille or Morel Piccolos, but for a budget to intermediate, these are a killer deal. I couldn't be happier. About the compatibility, they aren't a perfect fit in my dash, I had to drill a new hole (which was a pain because of the tiny space between the dash and windshield) and screw it in using a small crescent wrench, because of the difficulty of using a bit by hand. Now that I've done it once, I can use a small phillips tip bit and do it by hand. So worth it. ... show more

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. ... show more
