You put some good bass in your car, but now your speakers just aren't hanging with your subs. Kicker designed their KS Series speakers to deliver the performance you need to bring that "live music" experience to your ride.

The KS40 4" 2-way speakers use heavy-duty polypropylene cones supported by Santoprene rubber surrounds. Each speaker sports a 1/2" balanced dome tweeter that broadcasts plenty of high-frequency sparkle, so you'll hear all the sonic details that make your tunes exciting.
