I'm thinking of hooking up my subwoofer to my receiver, but have run into a little conundrum. The subwoofer I have is passive and has only a double wire for a connection. I found this amp, seems decent...at least for what I'm wanting to do.
I have a few questions. First question, this amp shows a gain switch. What does it do and what should it be set to? Second question, the freq knob doesn't have any numbers on it. What should I set it to? Third question, my receiver has it's own subwoofer volume. What do I set the amp's volume to?
