I have an audio control 3.1 in my TL-s and I was wondering if anyone had advice on how to set the volume and gain vs the head unit volume. Right now I have the 3.1 volume set almost at zero and I use the stock HU control the volume. I have the gain set at 0 (it ranges from -12db to 12db).

I'm running an eclipse 4ch amp to focals all around if that makes any difference.
