It works great now,, I HATE when something like that happens, after you've done other maintenance, But the problem is coincidental... (I really don't think I disturbed those connections when I hooked the LL up,, the OTHER end of the RCA's hooks to them, and I've got zip ties on the loop of excess)
So, I have one other question now for those who are in the know with the "Flash" (or lack of one) and LL..

Does anyone else who has bass and treble adjustment have a video of how much it changes? Mine seems to be quite flat still, barely any audible difference in minimum bass to full bass.
