They're going to charge me to flash again and I want to get it right next time.

I agree here. My system is setup fine sound wise. I did the install myself and had my buddy who knows the audio side from years of installs get me dialed in on the amps/gains/etc. Had the car audio shop with the Rockford flash equipment do the flash. I believe they set me up with the incorrect flash (makes sense logically, based on 4 speakers 1 amp) but the particular flash I have disables fade apparently. It's more annoying that the option is there and it doesn't work. I'd rather it work or be hidden.

i suppose if you just played the same song over and over under the same conditions it wouldn't matter...

I would suggest that if you got to have it flashed again, then be sure the fade works before you pay for it. Like I said, I had fade on my HU after the flash so it my opinion it has to be the flash you had done wasn't a flash that emabled the fade to work. I like the idea of having fade and use it for different songs going down the highway.

I am simply inquiring into which flash setup, for other people with similar or same audio systems that have working fade, works for them, or which flash I need to have the fade option hidden if it will not properly function with any flash w/ the Rockford Fosgate setup.

The purpose of the RF flash is to flatten out the eq curve of the hu so you dont have distortion at volume. Some flashes will allow fade and some will take the option off the screen but not all will flatten the eq. If you change the flash make sure the sound quality is good before leaving.

I'll preface this post by saying I have limited flash experience.
From what I can gather from experience and reading posts, the 0 amp, 4 speaker flash is one that enables fade. The flashes with amps added eliminates the fade because the fade control is done from the Boom amps, not the HU.
That said, 0 amp 4 speaker flash gets you fade, but you'll then have to address the eq curve with a BT355 or a dsp.

If fade is ur thang, ditch the RF flash. Get the HD Ultra flash of 0 amp 4 speakers and add the BT355 Line Levelers.

I will add that after having the indy flash so I could have fade and not need any line levelers, the SQ suffered. The signal was so flat that the lows just didn't pound like the 4 channel/0amp flash with the LL in play did. All the lows were there but it just didn't pound and SQ was not as good. With the flash for 4 channel/0 amp, you will have full fade control but need the LL to curve the boom signal. After tuning the line levelers, you can achieve a good SQ from the boom HU. If I had to do over again, I would just kept the 4 channel/0 amp flash and tune the LL's. I opted to go aftermarket and installed a sony 5000 and glad I did. SQ is 10x the sound over the boom HU and with the 10 band equalizer, I can adjust all the signals for that perfect tune.

I don't have any personal experience with Rushmore head units, but I read an article somewhere that made me THINK I understand what is happening.
There are internal audio amplifiers on the Boom head unit, just like the pre-Rushmore HK head units. The fade function is "toggling" the two internal amplifiers inside the head unit. Now that gives you fade, but it also gives you "speaker level" outputs instead of "line level", "low level" or as some would say is a more appropriate description "preamp" outputs, meaning you are picking up the audio signal BEFORE anything amplifies it.
This is why aftermarket and pre-Rusmore HK head units with preamps installed by IC sound so clean. The BikeTronics line levelers can account for the EQ curve of the Boom head unit somewhat by using their internal circuitry, but they cannot "un amplify" the signal that was just amplified in the head unit. It is still dirty compared to a true "preamp" signal. That is why guys like Haze and others that want the cleanest signal possible go with the flash that ditches the fader because it picks up the audio signal before it makes its way to the two internal amplifiers.
The end result is a cleaner signal but it is picked up before the fade function so it is only two channels instead of four.
