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?
