2. There are 4 pairs of RCA connections on the back. Sub, Rear, and Front
plus a "Fixed Out". What's this for? The manual shows it in drawings but
never references it in text.
They are "deadouts"... they are line level signal outs that would go to an
external amplifier if you had one... Make sure you dont have one before
installing the unit...
