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.

Really Surprising for the Price Point
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!

純正からの交換で音質アップ
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。

Buen sonido
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.
