Kicker 51KSC2704 KS-Series 2.75" Midrange Speakers, 4-Ohm, Pair

No joke, it’s been over a year since I bought and installed these into my 2011 Nissan Altima coupe, and they are still as good as the day I bought them! Will definitely keep buying from Amazon and this seller! Very very satisfied!

Installed to replace factory speaker with new head unit.With factory radio didn’t sound good because it puts out 2ohm vs 4 which is recommended for these speakers. Once I changed the factory radio. Boom! Sounds awesome.

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 brackets2 Chrysler/Jeep brackets2 Toyota/Subaru bracketsTwo 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.

I replaced the OEM speakers in my 05 Miata with these and they pretty much dropped right in. I did have to replace the head unit with something that had a bit more power to it, but all in all it is wonderful. These things are LOUD. With the top down and at 50% volume you can hear my music from down the road. Really great build quality. Has tons of power. They look killer once installed. All in all, wonderful speakers for the money.

Perfect fit for Gen 6 Camaro front dash corner speakers. Even came with metal mounting bracket that was exact fit and comes with bass blocking caps. Sounds great.

Put these in my 4430 John Deere and they sound great!

Extremely clean and clear sound
