I have a Bose system in my Escalade. It sounds really good for a stock system. At least it drowns out the sound of the Caddy guzzling down premium fuel like drunken sailor! Lol.
Buddy of mine has one of the complete cube systems for movies. Does not sound too bad watching movies. When he plays music it’s bad! Like real bad. He thinks it top notch stuff. I just nod my head and agree. Haha .
