hey Mario that worked perfectly at 33 ohm. I will continue with increasing the resistance until it starts to fault. do you recommend a certain wattage or is 1 watt sufficient?
Hi, I'm glad you solved the problem.
Generally, the amplifiers already have a 1k resistor that couples the primary ground with the secondary one, the reason for which your amplifier had the anomaly, could be tied to the failure of that resistor or to a problem with the microcontroller that manages the protections .
By making this change, you have bypassed the problem.
But it is necessary that the resistor is as high as possible to avoid strange noises in the speakers.
1W should be fine, but you can also use 2W.
