I just got my 2018 Silverado 1500, Crew cab, Z71 with Bose speakers, brand new. The speakers are terrible man, go with a better option. I’m planing on swapping them out ASAP. They distort super bad, I am confused as to why Bose would even put their name on such a janky setup. Let me put it like this, when I replace my Bose speakers I would not even GIVE them too you lol! They belong in the trash and I wouldn’t give them to anyone that wants a good sounding stereo.
