Yes I noticed that it increased with the latest iteration of the sound system. Previously I was using high level inputs and didn't notice it as much. Gains set using SMD-DD1. 0db 1000Hz for head unit, -5 db 1000Hz for the PSM and Amp gain settings. It is only really noticeable at low or no volume.
Thanks for the input.

Fronts and Rears at + 5.5 (where the SMD-DD1 shows distortion at -5 db 1000Hz), then very little gain at the Arc 600.4 amp
Horns set at -10 (Small kenwood amp had no gain control) still has some small gain hiss at low/no volume
BTW I have all of this crammed in the fairing of a 15 Road glide (except for the VO-M6x9s that are in bag lids) so getting to the gain settings of the Arc 600.4 is going to be a nightmare again.

It could be a factor as well but I don't know much about the DSR. If the things mentioned above are not in sync then the DSR could very well be the culprit.
I'm no DSP expert and throwing darts here but based on what I have seen in the DSP world is a simple scenario where the amp gains are high and the DSP is having to pull everything down or vice versa where the amp gains are too low and DSP is working too hard. Find a balance seems to mitigate some of the exposure.

I have a ton of floor noise with my ARC. Tried a few different settings. So I thought about it for.......about 2 seconds and just decided to crank up the tunes and leave it! I don't hear it then

Prob 1000 ways to break the code but I'm enjoying tinkering with and learning the various strategies.
