I'm two weeks into ownership of my LC and need to do something about this "Premium" JBL system. Based on what I've read so far the Beatsonic seems to be the first step with minimal cost and effort.
I know there are 2 versions, one with a connection for a subwoofer that requires a separate volume knob. Is there any reason I couldn't use the version without the subwoofer connection and still add a powered subwoofer later if I feel it's needed just by hooking it up like it were a system without the Beatsonic?
Hopefully I'll be satisfied without the subwoofer, but if I decide to add one later I'd rather not have another volume knob. Haven't played with car stereos since the late 70's so subwoofers weren't even a thing yet.
