Kicker

No sense in dancing around it — if you're looking for an affordable upgrade from factory sound, Kicker's CS Series is one of the most popular choices. These tough, dependable car speakers have a devoted following and for good reason. You'll get classic Kicker quality that will elevate your music to a startling level, revealing more detail than you ever heard from your factory speakers. Kicker's 43CSC464 4"x6" speakers feature a polypropylene woofer that delivers a solid sound with the help of a polyester foam surround that will stay strong for years to come. The 1/2" PEI balanced dome tweeter adds crisp instrumental and vocal detail. You'll get good results powering these speakers with a factory radio or an aftermarket car stereo, but they'll knock your socks off when you drive them with an external amplifier. Grilles are not included; the factory grilles should be suitable for most applications.
