Preface: have ran through several searched threads looking for answers, which may have confused me even more.

I have installed the Rockford Fosgate Fairing and Saddlebag lid speaker kits in my '18 SGS. I had the Boom head unit flashed at an audio store with the techno research equipment. They flashed me to 4 speakers, Fairings, Saddlebags, 1 AMP. I installed the RF kit per instructions, and also installed rear speaker output to amp rear input harness (https://vtwinaudio.com/product/v-twi...kit-3-2-2-2-2/ ) and switched the amp to 4 Channel mode; I feel like RF should just provide this with the kit.

Sounds great, much better than stock once tuned a bit. HOWEVER, the Fade control does not work on the head unit. The option for fade is there, but does nothing, cannot even adjust the indicator. I thought by adding the rear output harness and going to 4 channel I would gain fade (didn't work at all the way RF tech and/or instructions asked for w 2 channel of course).

What flash do I need to for the Fade control to work on my setup? OR will Fade simply not work at all not matter what flash I have as RF have informed, and I should just go back to Fairing Speakers 1 AMP flash to remove the Fade option?

Thank you.

 

We don't use that flash at our shop, but with the one's we've used you lose the ability to fade. The way "Boom" flashes work is that fade is controlled by the output at the Boom amp. With no Boom amp in place for it to control, there is no fade function.

 

That doesn't make since to me. You have the fade control on your head unit but it doesn't work? Does it move from front to rear or when trying to adjust it does it simply not move and stays in the center? It sounds like you have it wired right. Front channels from the 2 output off the head unit into the front channels of the amp amp and rear output from the rear (one connector) to the input of the rears on the amp using the harness you stated. Amp is set to 4 channel input. No line levelers in play since you have the flash done.

 

What flash do you use to enable fade? I had my boom flashed for 2 amp/6 channel at a local indy and my fade worked just fine until I switched to the sony hu.

 

The fade function is disabled with the flash. I installed my gear myself, and had the audio store flash the head unit and then tune the system. It is intended to be run in 2-channel mode. Once dialed in properly, you shouldn't need to mess with it anyway.

If you really want to run in 4-channel mode, you'll need a different flash that enables fade.

 

We never use fade.

 

The fade option is there, shows up. But you cannot move it left/right (F/R). It will be stuck at a random spot each time the bike is started. No adjustment happens.

Regarding how I have it connected. Originally with fairing and lid speakers had just the front input on RF Amp, Amp set at 2 channel. All speakers play, no fade. Then got the harness to plug from Boom rear output to Amp rear input. If Amp in 2 channel, no rear sound, if set to 4 channel, I have have sound/music at all 4 speakers. But still, the fade controls do not work. The control option is visible and not 'grayed' out. It just doesn't react to any input or move at all.

 

Which flash do I need that enables the fade to work properly? I tuned the sound stage and it sounds great, but i want the option to fade front / rear or if not possible at all, want to flash so that option doesn't show up on the head unit.

 

This behavior is normal for disabled fade function.
I have no idea. Professional audio installers will tell you not to enable it. It should be set up properly by them and left alone, else you run the risk of blowing speakers by setting the bias wrong.

I will tell you that my system sounds great at speed. I would like more bass, but you have a trade-off to accept. Bass is useless at speed. They set them up for high-pass only and then set the fade accordingly. Mine sounds very balanced even at 80 MPH. I have no need to adjust anything.

 

I don't see how fade can blow a speaker, it lowers the volume to one set, not the other way around. my dealer flashed mine for zero amps 4 speakers, and my fader works perfectly.
