2013 Volt volume not loud enough and being inconsistent

I've tried messing with the autovolume settings to no avail and I'm stuck. Basically, even at 45 the volume is often not as loud as I want it to be. What's more, sometimes the volume does get louder and fit my expectations. When I turn the car off, the volume will lower to play the sound effects, but then it will turn the volume up to where I'd have wanted it to be, but refuses to get that loud normally. I'm really confused here. Help?
