are you talkin about derricks teg? his stetsom 7k at slamology was hot as fuck. it was like 95+ outside and the car was in direct sunlight...no shade anywhere, i still have wifebeater tan lines from june lol. but when he opened the hatch of his car it was probably 40 degrees hotter by the rear of the car from the heat of the amp. it didnt miss a beat and he did consistent mid 150s demoing all day. very impressive imo
