As per the title really, Is Dudu7 a bridged amplifier?
I ask because I have bought a 2nd amp (16pin in and out to suit the android head unit, from Aliexpress) to provide plenty of power to my new car speakers. I would like to check the final output signal to speakers, when the gain is increased on either dudu, 2nd amp or both, that the signal frequency isn't clipping badly.
I have an oscilloscope and probe with ground connections. I will play a test 1000Hz WAV file from dudu to 2nd amp and out to dummy load resistors (4 ohm 100W). But, I'm not sure where to connect the ground on the probe - to the dudu chassis perhaps? Could depend, though, whether the amp(s) are bridged or directly grounded... I understand the dudu has the ground wire from the 16pin connector, does this mean it isn't bridged?
