Don’t know too much about car speakers, but after installation these are pretty nice as far as I can tell. I have a 2017 Kia Forte LX. Watched videos on YouTube showing how to install by disassembling the door panel, taking out the old speaker and rigging the old bracket so the new speaker can fit, but I skipped the rigging and just bought new brackets and harnesses from Crutchfield. Got one new speaker in and compared it to the old speaker on the other side using the radio balance, and the new Kicker is definitely better. Much more clear and just a bit louder, since I don’t have an amp yet to boost it to full potential. Unfortunately, I broke a couple of the door clips and also the handle mechanism allowing me to open my door from the inside. *sad emoji*. Just be careful if installing yourself.

Very easy install with a harness and speaker adapter to fit my door speakers in my Acura RSX. Note: 6.5” will not fit the rear speakers, used 5 1/4” for the rear, also with a speaker adapter and harness. Both sizes of this speaker produce a very high quality sound. Perfect addition to an aftermarket head unit. Best bang for your buck to upgrading your stock speakers.

Great sounding speakers for the money. These were installed in a 1987 Buick Grand National. Absolutely no modifications necessary. It is a fairly shallow mount speaker that works great for doors or tighter locations. Overall sound performs better than expected for a speaker at this price point. I would definitely recommend these budget friendly all around good quality speakers.
