    Kicker sound system

    I got 4 of the Kicker KS series installed in my car to replace the factory speakers a couple days ago. The sound quality is great and is very clear. They hold up very well when the volume is maxed out. I also got the 12’ down firing sub paired with the CXA400.1 mono amplifier installed. They blend very well together and are all add up to a great quality sound system. This was my first sound system upgrade I’ve had on any of my cars and it’s blown away my expectations
