Was the mirror in direct sunlight on your ride there when the mirror was moving a lot? My mirror likes to pivot with ease when the sun has been on it for a few hours to loosen up the ball on the mirror where it moves around. When it cools down the mirror is harder to move and slight hits from like my mids wont really phase the mirror as it would if it was super hot from being in direct sunlight. I never play with my mirror much other than when i get the feeling to crank my sub up i take the screw sitting in my center console and unscrew the mirror, take it down and slam away. I have broken 2 windshields already from keeping the mirror on and having it take a chunk of glass off with it when it breaks free and then spider out a bit from there.

No not at all it was much quieter, I noticed as soon as the bass kicked in. The mirror was just more that made me wonder. I just went out and played them for a little while with a buddy and they are back moving my mirror down after a while with it being much cooler and night time. These subs legitly like to be warmed up I guess? It's really weird to have them quiet down a bit then be back loud.

Same thing with what seems like every setup I've ever had. Its weird and dont really make sense, but I just need to play them medium to loud volume for like 5 minutes and then they are good to go but if I just go and crank it to the max it doesn't seem no where near as loud.

Theoretically subs need to wram up before overpowering them (such as amplifiers also) so that you have a smooth transition in temperatures and protect their voice coils (metals obey the law of shrinkage-expansion). In practice, we have seen that you can hit bigger numbers in sound pressure levels while overpowering your voice coil when it is cold than when it is warm. That's why there is a difference in official and unofficial term lab measurements (has to do also on how charged are your batteries and how cold are your amplifiers and we are talking about a tone). Also, practice has shown us that you can overpower your voice coils several times without damaging it when it is cold for very shot time (damage comes when overpowering on the same watts for much time due to high temperatures). This is against theory.

So to sum up, I am a person that believes in theory and.

a ) If I am to play music I overpower x2 (and after a while could wo to x3 but not for too much time) having my amps and speakers-subs warmed up.

b ) If I am to play a tone I overpower x4 with everything cold.

i have a truck like yours and my mirror flexes like crazy when the sun is on it for a while or when it gets hot out. maybe you parked in the shade but try it again when its hot and it might do it.

The density of the air in the sealed enclosures might have something to do with it?

Once warmed up the density decreases and that might allow for more travel and with that more bass?

^^^ This is just a guess.
