It's time for an upgrade
Upgrading the old factory speakers in your car will give you a huge bump in sound quality, and Kicker designed CS Series speakers to get your sound system rockin' without breaking the bank. You'll enjoy your music even more when you hear all the details that your muddy-sounding factory speakers couldn't begin to reproduce.
Built tough
Kicker's 40CS684 speaker set provides low-end from a tough 6"x8" polypropylene woofer, with a polyester foam surround that will stay strong for years to come. The 1/2" PEI balanced dome tweeter takes care of the vocal and instrumental details that'll really bring your music to life. These speakers sound great powered by a factory radio or an aftermarket car stereo, and they'll really rock when connected to an external amplifier.

I installed four in my Expedition and they sound great. Plenty of bass and no need for the sub I was planning to install. Crisp and clean highs, highly recommend if you like classic rock.
