Hi all - sorry I don't mean to bump up a dead thread. I just bought a 2015 Yukon Denali and trying to learn what is an easy upgrade and what's not worth it... Coming from a Ram 1500 where I always upgraded the factory speakers (have had 4 of them), one thing learned was the factory audio was always crossed over and really limited what you benefited from - especially the front door speakers.
So, the question is on the Yukon (or at least 2015+ models), are the front door speakers truly 3 way or are they already crossed over and limited on what sound is actually sent by the factory unit?
