During the SEMA Show in November, Chevy’s exhibit was pretty much dominated by the subcompact Sonic. Yes, there were a few other notables like the COPO Camaro Concept, but there was a Sonic for every day of the week, one of the most notable of which was the Sonic Boom concept — with its enormous audio system, which I like to refer to as its “bass cannons”. And having just finished a week of living with the Sonic, I do have a few things to say about its standard audio system (but you’ll have to wait for the review and our pretty pictures for that).
Interestingly, there is a new rumor that involves possible production of the Sonic Boom concept, which is backed by a recent U.S. Trademark filing by General Motors. The trademark has been reportedly granted final approval.
If true, then we may see something unprecedented in terms of factory sound systems in small cars, but probably not to the extent of the concept. Hopefully it is true.
