I'm very sorry for wasting your time with such a stupid question, I deep down know it's fine, but I just wanna be sure, I'm a little OCD, as you can probably tell.
I live in Melbourne, Australia. I drive this car: https://www.carsales.com.au/cars/details/2020-mg-mg3-core-auto-my20/SHRM-AD-6089752/?Cr=1
I put it in the boot, which I believe is called a trunk in America. I didn't take it out of the box, or the bag. I did some other stuff after, so it was in there for about four hours. It seems like a fairly hot day today.
After doing a tiny bit of research, it seems like heat can damage a speaker. However, I'm too lazy to read the details, I'm sure it has to be in circumstances very different to this.
But just confirming, there's no chance it will make even a tiny difference to the sound, right? I mostly got it for the music.
