Do a search on the basslink... personally it sounded very nice with it's 200watts power. Doesnt take up alot of room and can be placed vertically or horizontally. Randy have you even heard of the basslink in a car before you made your opinion?

As for components that would sound great using your HU power...I recommend some Rainbow Dreamlines from ampmanaudio for $129 shipped. They are very efficient and sound great for Rainbow's entry level component set.

If not those then I would suggest the Type-Rs.. they do need power for them to sound their best.. but for temporary play I've heard them off of a pioneer DEH-4400 which give about 15-17 watts.. and the speakers sounded nice. Depth will be an issue..so be forwarned.. you might have to invest in some MDF to space them out.
