I was tryin to sell mine for 350... I was unfortunate enough to have two other guys selling theirs for 230 at the same time. Which I asked em why their were soo cheap. They retail at like 550... My gain has always been set all the way, their is no need for more its running at ****ing .5 ohm daily its a ridiculously loud system but craves power. I get tired of people telling me their shits louder than mine when I broke the ceiling to my truck with my system. Im thinkin bout upgrading my system to two 15 XXXs god knows im already going deaf now. But im gunna run ma audio again. First amp Ive never had problems with. Overheating, or repairs. ****ing **** is amazing for the money. good luck to you n the sell... im pumped i just bought giovanni 22"s today.. .got hooked the **** up too..
