We just bought a 2018 SG CVO and absolutely love it, but we have very low volume. Doesn’t matter what media we use, FM, XM, AUX or Bluetooth. We have checked every volume setting on the Boom Box radio and nothing works. Any ideas?

 

i'm assuming you are blue toothing with your phone, did you also turn up the volume on your phone?

 

Just spit-balling here.....Does it have the stock audio system, speakers etc? Could the previous owner have had it flashed and removed the amp? Flash and no amp means low audio.
