    Re: Max gain?

    What volume are you setting gains at? If you're up at .25V, you are getting low voltage from your HU. Should be higher than that.

HPF is 80hz constant and my speakers **** at mid bass so I had to take it out of them. I think my equipment is just weird because my sub can beat. Even the guy at my local audio shop could not believe it was a 10" and my amp never gets hot. Maybe I just got a frankenstein amp :/
    You NEED a DMM or 'scope. If your HU has 5V preouts and your gain is at max you're probably driving the amp to full power at 1/4 volume. Above that the amp just clips. Not getting hot is meaningless.

    Op buy a dmm, they are cheap.( Less than 20$) and set your gains properly.
