The LC-1 can't amplify the signal (assuming we're talking about the same LC-1, the thing that goes on the RCA cables). It just lets you reduce the signal that the HU would normally send the amp.Aight.
I have another q for you... I am using the LC-1 bass knob and it goes from -8 to +8. Should I be having it +8 or can that cause clipping of the HU signal?
