I am going away to Wales for a week in a carravan in my car with four mates. I have given them strict orders to keep their weight down. I have sent them all on strict diets of cabbage and lettuce and if they weigh more than 9 stone they are not allowed in my car. However I am thinking about taking my amp and speakers, is this madness? I just find the sound of portables and computer speakers hightly offence.
