won't need any of that. i'm not saying a sanctioned event because those i know take time and money i'm saying making up your own rules. just plain and simple "what sounds good to norm" or whoever wants to do the judging. All you do is just sit in a car, play your favorite track, then go sit in another car play the same track and repeat for all the cars in sq.

Car that sounds best wins. No metering or "official" judges just plain and simple, what sounds best. You can take install somewhat into consideration. Not an official sanctioned sq event, just a single category sq with your own rules and your own judging to what works the best and easiest. Only extra cost would be one extra trophy and some time from whoever wants to play judge that day but you'd get plenty of sq cars and it would pay itself off in no time.
