2016 vw jetta gli with fender system. Stock is very very clean and moderate loud. Good mid bass presence but muddy overall. Tweeters are sharp and beam easily at high volume.

Currently running it with a SI 12, on 650watts. It will easily overplay the front stage

Yeah absolutely this. There is a way that everyone wins here. I will say, I lean more to the side of “it’s my place and I will play my music how I want” but there is a tactful way to approach it. Obviously avoiding quiet hours, and decoupling your speakers as much as possible is a logical step. But it’s impractical for them to expect silence too.
