I am about 1,000 miles in on my new 23 Turbo, and loving it so far. I was happy to see that it came with a capable Bose 10 speaker system. I am still getting used to the settings, and trying to fine tune the best possible sound from them. I know that the sound quality from Sirius XM is seriously lacking, but I do still use it for convenience, and some news and talk radio. For music I prefer Apple “Lossless” plugged in via USB. I am struggling with the Linear options and the different settings under that. For some types of music it sounds pretty good, then for others not so much. The system seems to lack the richness and fullness at lower volumes. It is only when I get about 35 that the system seems to kick in. While I am a fan of Bose products ( all of my BT speakers are Bose)this one seems to be a little lacking. I am just wondering if there is an ideal setting that will help at lower volume. Jazz, classical, & big band do not seem to sound as full as pure rock music. On the other hand rock music really makes this system sing, and the clarity is pretty darn good for a factory stereo.
