I noticed that a little at low volumes... but past 50% they are a little louder than stock and substantially clearer. Like was mentioned earlier, maybe need an amp?
Ordering from Crutchfield they came with plug and play harnesses that used the factory connector. Along with mounting brackets, although I didn't need those for my install.
I installed these Kicker's in my 2020 and they sound awesome. Impressive amount of bass for not having an amp.

Glad its not just me. I top off the oil every fill up, by the next fill the oil isn't even touching the dipstick.
Have never seen any blue smoke and there are no leaks.
