Hi there. I'm Rick. I own a 2014 Silverado and want to mount tweeters in my A-pillars. I saw in a thread that you mounted Audiofrog GB25s in the stock speaker locations with the tweets close by. Did you mount them in you A-pillars or sail panels? If so, was it difficult? Depth, angle, etc? I haven't seen many builds with similar vehicles who did this so I'm anxious to hear any info you might be able to provide. Thank you kindly.
