as far as how well it sounds. I went from 6 12's in another vehicle to the 1 ten, and i am satisfied *(not to say that it hits like my 12's, but it will rattle mirrors and what not). Over sound quality is excellent.
My other ride is a helicopter, it has 420 shaft HP derated down to 317 by the tranny (thats all it can take)...I'd rather take the Z.
