I have noticed that when turning on my amp I must "kick" the volume up so the LFM-2 will sense the signal. Since I find this to be a pain (especially at night when folks are trying to sleep), and enjoy the sub even at low volumes, I have turned the sub to the on position instead of auto detect. I don't mind leaving it on all the time unless it might potentially harm the sub or shorten it's life expectancy. Also, it is too dificult to reach behind it to turn it on and off all the time.

Feedback please???
