This right here, highlights the problem with some of the people on this forum and all over the sound community. They don't watch voltage, and they just crank their amps up til it sounds "good" and let it go. Meanwhile, their alt and batt are suffering horrible and painful deaths, at the same time as possibly frying the amp....
I have learned, a "few" people on this forum know what they are talking about, and when they speak, I listen. Sure, sometimes they come across a little arrogant or assholish, but, when you have been in the game for so long, you expect people to already know what you know sometimes. Sometimes people forget that people are still learning. But still, I listen. If you choose not to listen when people give good advice, then you, my friend, are in the wrong place!
