Default Trying to help a friend with info - 2011 GMC Acadia with Bose

My friend has a 2011 GMC Acadia with the Bose system. He thought without spending too much he could upgrade the speakers for a better sound. He bought some decent Focals (I don't know the model). The problem is the small separate tweeters that are on the a-pillar keep blowing. There just is not any information online about the Bose amp so he has no idea the amount of power it is putting to the tweeters and what frequency the crossover is set.

Does anyone know how much power and over what frequency range the Bose set up is driving the tweeters?

Any recommendations on different tweeters that could be used as factory replacements in this application?

Is he running any sort of external crossover or did he just wire them up To the factory tweeter wiring? The factory tweeters probably have a small capacitor attached acting as the high pass filter so if he just wired them up then he would be playing them full range which would blow them fairly quickly.

Trying to run different speakers off the factory Bose amp is really a waste of time and money. He needs to run an aftermarket amplifier at a minimum where a crossover can be set, this will sound better and keep from blowing the tweeters. The factory tweeters are wired in series with the door speakers so there is no crossover in the factory amplifier.
