I understand your suppost to turn any bass boost off on your HU when you have a sub, but was wondering if the setting goes from -8 to 0 and on to +8 if it would be better to but it at the bottom setting (-8) of nuetral (0).
It is a subwoofer level control..... setting the gain with it a 0 gives you room for adjustment. You can also set it with it all the way up to make it impossible to clip the amp by changing the setting.
