Review: 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.
Review: 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.
