Ok, so even though I've been selling car audio for 8 years and been a hobbyist for 13-14 now since I was a kid, I've never heard of "the Big 3" until a few months ago. I've tried doing some research on other mobile sites but it seems that the only reviews I get are from what seems to be amateurs and a few knowledgeable people don't like it. Seeing this is hard to tell without REALLY knowing the people, I want to get some of you more technical nerds around here a shot to talk about it. What's your opinion and experience with the big 3??
