Helix Sub and OBD11

after installing my sub I get errors showing speaker not working, but they are all working , also the fader control will change to just a left right slider not the car image and button, I assume a sensor thinks it is a different model amp/headunit, If I Reboot the head unit it will return to "normal" , is there and coding that would correct this?

Please tell us more about your setup. Is it just the sub? Or is it the entire Helix system?

just installed the sub, I think because it powers the "new" amp later than the head unit it errors as open circuit to four speakers, if I reboot head unit it returns to normal as the helix amp then has power.
