RE: Truck
take a look at the 10" mtx truck box speakers if they will fit behind your seats. they also have a built in horn-loaded tweeter so leave yourself some extra speaker wire (about 10 feet) and you can bring one of them out at the parties and set it on your tailgate. your have thumpin bass and pretty much a full range speaker. you can get them at crutchfield.com if you are interested.
