M5 a troll? This forum tiny? People don't like coming here? No one said you were an idiot, but if you want to run back to a forum to bash this site instead of making an effort to work with the people who are offering you assistance, then it shows why you're on that forum and not here. Not trying to start anything, but on this forum, we try to take an intelligent approach to problems or questions, and usually that entails starting out with the most information possible before just tossing out answers. As for how your setting your gains, good luck, I continue to see topics showing up across the net with blown sub woofers from installs using that tool. If you want easy answers with minimal information provided while not really making the most of what could be, you were in the right place before. If you want to do it with a little more planning or preparation though logical discussion, then this is the correct forum.
