Fader controls
Ultra... could I just splice into my front speaker leads and run those wires to my amp's rear inputs to power the rear speakers? I know I wouldn't have fader control, but I should at least have some sound in the back. What do you think?

Damn, why does something as simple as turning on rear speakers have to be so difficult? For all the money I paid for this bike I should have some control over what my sound system sounds like. I'm getting extremely disappointed in Harley management and their products. I've purchased 4 new Harleys in the past 12 years...this will probably be my last one...sad to say, but I can't cave in to company exploitation any longer. This is getting ridiculous, to say the least. I'm not going to purchase any more gear...guess I'll ride around with rear speakers that don't work, and I'll let every one know the reason why!

it's never been standard practice to combine a single high level head unit output to feed 2 inputs on the same amplifier. Whether or not it's technically feasible, I'm sure it is but you're then screwing with voltages being divided, increased THD, and decreased impedance on those outputs. IMO, you would be better off using something like a PAC SNI-35 to convert those speaker wires to RCAs then Y off the RCAs into the front and rear inputs. This keeps the left and right signals balanced and isolates front and rear from each other. Just my .02.

SunPilot what bike is this by the way? If pre 14 then the rear outputs on the head unit are already active, you just need to tie into them. You can either wire your own female pins and insert the pins onto the mating side of the radio, pins 1,2,24,25 or you could grab something like this that makes it easy for you

Usually 5-5.5 and which ever setting sound better and distortion free. It all depends on the speakers.

Local dealer let me in the back today to try some stuff. This is what I learned about 135_OFF.BIN. On a 14 FLHTK if you turn off amp1 and amp2, then select 2 amps installed and 8 speakers you get 135_OFF.BIN.
This flattens the EQ, retains AVC, retains Bass and Treble control but kills the fader.
It's more involved trying to set gains on the ARC amp, but in the end... I am beginning to understand what others have been saying all along. It gets way louder than I care to get without distortion now.
