I just installed my subs and they sound great, and everything is good, except for these two options.
The manual for the amp had a guide for setting the input gain, but it made little sense to me, and it didn't explain the reasoning behind the steps. So, I'm not really sure if I did it right. If I remember correctly, it's set about one third of the way up (120mV-6V.)
As for the subsonic filter, the manual has no guide at all, so I'm quite lost. It goes from 20Hz to 50Hz, and my box is tuned to 42Hz, if that helps.
So, anyone know how I should set these options?
