10w3v2d4 powered by 250/1 in a 4080 box (or Zenclosure) in my 05 6mt coupe...would this be enough power for everyday listening? nothing too obnoxious, and definitely be able to hear the boom...any input would be helpful.

 

Yeah, that's enough for what you say you want. It's what I have in my G (w/ 4080 box). I have the gain control set pretty low on my 250/1 and I get plenty of bass. I opted for the D2 wired for a 4ohm load which provides a little cleaner output, but probably not that noticeable.
