Anyone familiar with these amps? I have 3 of them and I am trying to figure out what the switch on the bottom actually does. It has an "H" and "L" which I thought would be high/low pass filter, but it doesn't seem to make an audible difference.

Also, Is the Remote and ACC relay on these amps known to go bad?
