Ding ding ding! I'm extremely happy with my current set up. The 6X9's handle my bass pretty damn well for being 6X9's. BUT, a sub will let me reproduce my highs and mids more faithfully, and I won't have to drive my speakers as hard to get them to be louder and clearer at the same time. That's what I want the sub for. To take the load off my speakers, and maybe so I can thump once in a while. I don't care for having 2 12's in my trunk trying to rattle my center tail light and spoiler off. That ain't me.
