so just a little update after nearly a year of use. I have had the amplifier running at 1 ohm now for about the last 6 months, set the gain the with an O-scope and it never gets hot. However I have ran into 1 problem.... the onboard fan. The fan has become increasingly louder now for about the last 3 months. It finally got so bad I opened it up to see what size fan it was and if i could just swap it out with a normal computer case fan.... you cant. the fan is only 1 or .75 inches in diameter. . . sad face. I gues 113 dollars for an amplifier for a year isnt bad. I mean the amplifier still works and doesnt get hot but the fan is too ridiculously loud now for me to seriously consider running it anymore
