My HU has a separate gain for the subwoofer outputs that ranges from -6 to 6. When I set my amplifier gain, what should the HU gain be set at?

Wait.. So you're saying that I should NOT have it set at 0? that would be like lowering my gains? B/C I was under the impression that you would want it at 0 b/c it puts a "+" infront of the number if it above 0 which makes me think that you're increasing the current power given to the sub.

I go full tilt. Set your gain to the max without clipping. Then full tilt is as loud as your allowed. I always found myself in the negatives for moderate bumping.

I say set your gain at 0, that way some songs have much more, or much less bass then others you can adjust accordingly....

I have mine set at -4, but then again mine goes from +4 to -25

I also say to set you gain at 0, other wise you will have no up adjustment for those sources with low sub content.

When setting gains you want everything to be at the max settings you are going to use.ie sub gain at +2.Otherwise you will clip the signal if you set it on 0 then adjust it to +2 later on.
