2011 s4 b8 multiple speakers blown?

[Geneahn]

So I know for sure the passenger front door sub is blown, at certain low frequencies when I push the volume it sounds awful like rattling. I went to a dealership and they agree that it's likely the speaker and not the door cause when we push on panels and the grill of the sub, there's no change in the rattling noise.

That being said, the tech said he believed the two left and right speakers near the front window were starting to die

When I took it to another tech, they agreed that the door sub was definitely blown, the window right and left were fine, but said they felt like the two tweeters near the rear view mirrors were going out because they were sort of quiet compared to the other speakers, in my mind they're going to sound quiet because they only output high frequencies right?

Obviously I don't want to replace anything that doesn't need to be replaced

Can anyone give me sort of a definitive what the window and tweeters should really sound like? Or heck, can someone sort of give me guidance on what all speakers should sound like under normal circumstances?

The only way to be 100% sure is to take out every speaker and play it on the bench individually.

I wish someone would come out with an adapter for the harness so you do not have to cut it to add aftermarket speakers. OP good luck and they are right best way is to remove them and look for damage to the speaker. Hard to believe the tweets are going, usually have to over power them to kill them and when they do go the sound they make makes you want to rip your ears off or nothing at all. At least that has been my experience.
