Mel, load one of those 800s up for the roadtrip down as well ;\)

I think the 500 would be enough sub to add to the sensation and even out the sound as it reaches low enough and has good power. I was surprised when I heard icehawks 500. It has more power/feel/sonic presence than I thought it would have.
