I have had this amp for about 2 years and about a year ago it stopped working because a resistor inside came off. It took me forever to find the exact resistor needed and when i finally recently replaced the resistor, it still doesn't work. It just turns on, clicks, then goes into protect. I have kind of gotten out of the car audio game and i am wondering if it is worth it for me to send it to get fixed then sell it, or to just sell it as is. The board looks flawless and i just don't have enough knowledge to diagnose what the problem is.
