I normally have my Non-Fader phase set to normal and the Output set to Mono.
What actually happens when I set the output to my sub to Stereo? Does the Eclipse unit attempt to send stereo signals to the mono amplifier or does it synthesize stereo signals to the amp.
All I know is if I set the Non-Fader output to stereo the sound changes to a louder, less tight output. It sounds more like the sub is in a vented enclosure as opposed the the sealed box that it is in.
Any ideas ??

The non-fading output is most often used for sub applications. In your case, it can also be used for MONO or stereo and perhaps is filtered too. (Sub MONO, Rear fill, M/B only in stereo)
In MONO mode, most HU's automatically sums A+B channels and feeds both stereo signals to a MONO output device like a sub amp. There may also be a filter in that part of the circuit to direct HP or LP signals to the attached amp.
In stereo mode, you may have Sub/MB/Full Range signals off these channels. If MB/Full Range is the primary setting for the filters, (HPF or full range) the subs will sound sloppy, poorly defined lows and a tad louder in the upper bass region.

This is likely to be a function of a HU filter that is passing more than bass signals to your sub amp. It will sound louder and a bit more muddied if the bass amp/sub are getting signals above 120 Hz. That's why we normally choose the non-fade output for MONO Sub only and use any LPF's in that circuit, set to about 80 Hz.
Use the settings that sound best for your subs. MONO setting and LPF for this channel, set for subs only. (~80 Hz.)
