Summary: I purchased these speakers to replace a blown factory speaker in my wife's vehicle. The speakers are excellent quality and provide a fuller, crisper sound. the installation kit worked great. Once again, Crutchfield provided high quality products at great prices.
Better than OEM, good for entry level or budget level systems.

Summary: I have always had a good experience with Kenwood products. The KFC-1664s speakers are better than OEM and a good choice for anyone who is on a budget. I had no problems installing them in my 2001 Subaru Outback Wagon. They are a direct bolt in if you reuse the OEM speaker's plastic shields. I also used 2 pairs of Metra 72-9300 - Speaker Harness adapters instead of cutting and soldering wires. The speakers sounded great at high volume with the OEM head unit.
Summary: Bought these to replace door speakers in my wifes 2001 Mazda Protege. They are a nice upgrade from the factory set. Paired them with a pair of Kenwood Excelon KFC-X693 6x9's in the rear deck and a Kenwood Excelon KDC-X997 headunit. As many reviews ive seen about the bass being bad they are correct but they knew that when they bought these they are 6.5" not 15" subs.
Pros: Very cheap and easy to install, clean clear sound quality at moderate volume (not full volume), voices and instrumentals very crisp.
Cons: Very little bass but was expected 6x9's in rear deck more than compensated for it. After all they are 6.5" not 15" subs
