Our take on the Kenwood KFC-1666S Car Truck Front & Rear Door Speakers

The Kenwood KFC-1666S is a 6.5-inch two-way coaxial car speaker sold as a pair, built for replacing factory door speakers. Each speaker handles 30 watts RMS and 300 watts peak, with a polypropylene cone and a paper tweeter on a flush-mount frame. It suits drivers who want a simple, low-power factory-radio upgrade rather than a loud amplified system. Against pricier coaxials it gives up bass depth and tweeter refinement, but owners of basic setups find it an easy, forgiving fit.

Pros
  • Pair of 6.5-inch two-way coaxials
  • Runs on modest head-unit power at 30W RMS
  • Polypropylene cone resists moisture in doors
  • Flush-mount frame fits many factory cutouts
  • Paper tweeter keeps highs smooth, not harsh
Cons
  • 300W peak rating overstates real power handling
  • Paper tweeter is less detailed than silk or dome tweeters
  • Bass is thin without an amplifier or subwoofer
  • Install kits only fit select GM vehicles
