Our verdict

For a simple, affordable step up from factory door speakers, the CSC65 is an easy recommendation: efficient, shallow and ready for an amp later. The honest limit is that a coaxial design will not image as precisely as a separate component set, and some cars need a mounting adapter or wiring harness.

Factory door speakers are usually the weakest link in a car's sound system. KICKER's CS Series CSC65 is a 6.5-inch, 2-way coaxial pair with a polypropylene woofer and a 1/2-inch PEI balanced-dome tweeter with a neodymium magnet, rated at 90 dB sensitivity and 40 Hz to 20 kHz. KICKER recommends up to 100 watts RMS of amplifier power, with 300 watts peak, so they suit a factory radio today and an amplifier later. A shallow 1-11/16-inch top-mount depth and included steel mesh grilles make them a straightforward swap in many doors.

Why you’ll like it

  1. 01

    Upgraded parts in a drop-in size: a polypropylene woofer cone and a PEI balanced-dome tweeter with a neodymium magnet.

  2. 02

    Efficient: 90 dB sensitivity gets good volume from factory head-unit power, no amp required to start.

  3. 03

    Grows with your system: rated for up to 100 W RMS of amplifier power if you add an amp later.

  4. 04

    Fits more doors: a shallow 1-11/16-inch top-mount depth, with steel mesh grilles included.

Great for

  • Drivers replacing worn or muddy factory door speakers
  • Budget car audio upgrades
  • Systems that will add an amplifier later

Maybe skip it if

  • Your doors take 6x9 or 6.75-inch speakers — KICKER sells those sizes separately
  • You want a high-end component system

Questions people ask

Do I need an amplifier?

No. With 90 dB sensitivity they run on a factory or aftermarket head unit. KICKER recommends up to 100 W RMS of amplifier power if you want more volume and headroom.

Will they fit my car?

They need a 4-13/16-inch (123 mm) mounting hole and 1-11/16 inches of top-mount depth. Many vehicles also need a model-specific speaker adapter or wiring harness, sold separately.
