I have a consistent slow clicking, low volume. that I hear through all speakers.
All used equipment except the PVR.
Kenwood Head KDC-BT645U
PRV DSP 2.8x
Alpine MRP-M350 (bass Amp) Chinese 4.5 inch subwoofer
Sony Xplod XM-SD46X Driving infinity 2 ways and separate tweets.
US Acoustic usx250 Driving rear single cone infinity
Total possible high usage voltage is roughly 50 amps per unit. I will never turn it up loud enough to
strike anywhere near that draw. 60 amp has been feeding fine for testing purposes.
The system will be used mostly via Bus main Batteries and alternators when driving,
which is a completely separate power path from the 48v to 12v/
I was looking to add a noise filter after the 48v to 12v converter.
Suggestions please.

Do you have an oscilloscope?
If you disconnect everything but the head unit and connect speakers to the head unit, do you hear the noise?
Do the lights on anything flicker when you hear the noise?

Have an oscilloscope, don't know how to use it.
I have not tried head by itself. Will now.
Lights do not flicker.
Thanks

I purchased one of the USBs connected to a PC from China... If I manage to see the signal, what does it tell me about click?
Set it to 5v/div, DC coupling, the lowest timebase setting that will let the trace run without a break (2ms?) and touch the probe to the 12v terminal of the amp/head unit, whatever. Do you see anything other than a perfectly straight line? If not, do any changes coincide with the noise?
