I have an amp (Boss 1500W) thats been acting weird. I recently started using it after not using it for a few month. It worked fine at first but now its going in and out randomly. Ive checked all the connections even with a multimeter and everything has power and its grounded. Power level is around 11.3V. Im wondering if any/most amps need 12 or more Volts to even turn on? Or maybe my amp is going bad considering its 3 years old.
