Hi everyone ! I have a Taramps MD 5000.1 amplifier that works fine on the test bench! The output off set is precise and does not give any problems! in the car, on the other hand, with the volume of the car radio set to 0, the amplifier moves the subwoofer back and forth, as if it were oscillating, then the oscillation disappears when the volume is given!

do the same thing! and it does so only if the amplifier is installed in the car! On the test bench I don't have this problem
hello Perry! Checking with the tester between RCA ground and GND of the battery gives me a value that should be the decoupling
I don't understand. Do you read 0 ohms between the head unit's RCA shield and the case of the head unit?
between GND RCA and battery ground I read 1.002

What are you using for a signal source in the shop, where there is no problem?
Did you check the head unit in the vehicle or did you check the one on your test bench?

Did you test the head unit that's in the car, where the amp has the problem?
Was the shield to the case of the head unit (in the car) 0 ohms?
