Summary: This application was for my 93 s10 standard cab. Not the best acoustic friendly environment, to rate speaker fidelity, not to mention physical limitations. But the main mission was to replace defunct OEM speakers, so anything was an improvement.
Pros: Good bang for the buck.
Cons: Although their claim of direct replacement, modifications were needed. Because of the offset of the speaker mounting surface due to the center cone (thicker), the mounting tabs on the original rear interior panel had to be removed because they were too short to accommodate the spin nuts. Conseque...
Summary: I bought these to replace the rear speakers in my 85 GMC K1500, and they didn't fit. My bad on that one, not docking any stars for that, but it's more of an FYI. The sound quality, however, left much to be desired. Quality wise, these aren't even as good as the $40 3.5" speakers I got for the dash.
Pros: + If your only other option is some 1980's era stock speakers, these are noticeably better + If you're not an idiot like me, these might be a straight bolt-up to your vehicle
Cons: - Not only devoid of low end sound, but it also makes the mids sound tinny somehow - For being seemingly designed for retro vehicles, the mounting depth is such that I don't know what this would actually fit cleanly
Summary: 4x10" speakers are a very odd ball size that make quality sound difficult. Knowing this going in to the purchase I thought that kenwood did an excellent job at creating a quality product that produces good sound at a fair price.
Pros: Great option to replace old factory speakers. Good quality sound
Cons: No fault of kenwoods just a horrible factory decision in speaker size
