    Got this in literally a day and a half and I live in Minnesota. When i first installed this amp, the gain was all the way down and my radio was at the volume I like to have it set at and it was already loud AF! I turned it up about an eithgh of the way and damn is it loud. You dont even need good electrical with this thing, it does rated at 13.8 volts. Thank you!
