My setup is :
Ugreen usb sound card (with rca output) -> ground loop isolator -> rca volume knob -> 2x Y rca splitter -> 4-channel amplifier -> car speakers.
Or you can use :
usb sound card (with 3.5mm jack) -> 3.5mm jack ground loop isolator -> amplifier with 3.5mm jack input. In that case you will only be able to control volume with key press on the touchscreen
i just made my setup like you said in my car : usb sound card (with 3.5mm jack) -> 3.5mm jack ground loop isolator -> amplifier with 3.5mm jack input
but i don't get the 3.5mm jack ground loop isolator yet. I got a lot of parasite noise in the speakers. Does the 3.5mm jack ground loop isolator solve the problem ?
thats almost the last problem i've got to resolve to finish the problem.
thanks for the reply
