in my 2013 (with bose) even with original CDs the sound was not loud enough event at maximum volume.
with the 2017 (with bose) the same tracks are now playing loud enough and I never had to reach the maximum volume to obtain enough amplification. On the quality side the 2017 is better too. the tiny 4" subwoofer in the 2013 was mediocre.
