You're welcome. Yeah, one 12 should be enough for sure. I would go with the Solobaric, personally, but that's a matter of sound preference. How much power are you thinking of running to the Solo? They are kind of inefficient due to their small enclosure requirements, so the Solo is probably going to require more power than the Polk. The upside is that the Solo (when properly powered) is usually quicker, making it a more versatile subwoofer than the Polk. This is all my take on the matter, of course.

And just to clarify, my roomate took out the headunit in his car, and his trip computer still works fine; he's just missing the part about CD track number, radio station, etc. The rest still functions as before.

Oh, and no one should ever apologize for NOT listening to country. Those that do listen to it, on the other hand...

For the Avant, I don't know. If the sedan has rear door speaks, it's news to me. HTH.
