just to close this out, i found out my bluetooth adapter wasn’t HD and the sub signal wasn’t coming in strong. when i replaced the adapter to a higher end, the sound came in beautifully through the line in port. thanks for all your help here.
Are you sure the cable from the Peloton is damaged or miswired? If the L&R were wired out of polarity it would certainly kill the bass output.
I don’t have a setup here I could use to test/compare, as I use the Sonos Sub, but I do recall a year or so ago, some users in the community here reported a similar issue about the Amp’s low-output for the .LFE port to a couple of different ‘brands’ of 3rd party active Subs and IIRC those matters were resolved sometime later with a firmware update - I think in those cases the issue was across all audio sources and not just the line-in audio.
I’ve not seen the issue reported here recently, but in those earlier reports/threads, users were asked by Staff here to contact Sonos Customer Care, so that the matter could be investigated further. Anyhow my thoughts are to perhaps report your findings to the Support Staff, but to first take several system diagnostic reports whilst playing from the different audio sources and make a note of the playing source and the diagnostic reference number.. and see if they will look into the matter for you. You can contact Support Staff via this LINK.

i totally understand that but at the same setting on the sub, the inputs from the amp change the amount of bass that comes through. it’s uneven.
Just to add there is no way to control the output level of a 3rd party sub aside from any manual controls on the sub itself. The sub output on the Amp is not variable, outside of the volume control itself.
it’s already at 10 and changing it up and down doesn’t have an impact. but also, changing that level doesn’t isolate more treble or bass, it just modifies the entire stream to be higher or lower sound.
Yes, appreciate the source-level purpose, I just thought if it was set low, then increasing the level may have helped a little.

Does increasing the Amp’s line-in ‘source level’ to a higher value, like 9 or 10 for example, help to solve the issue for you? Goto ‘Settings/System/gAmp Room Name]/Line-In Source Level’ in the Sonos App.
