I used the supplied RCA cable of the TV plus and wala naman ako na-experience na speaker humm, although for isolation try ka na lang din ng ibang cable.

Power source ko is tapped at the second 12V socket though, ymmv

Sir, When you say second 12v socket, What do you exactly mean?

Ako kasi ang ginamit ko is yung lighter plug-to-power i got from Lazada. Then bumili din ako ng 2-in-1 lighter socket para share sila ng dashcam.

Inisip ko din na baka nag co-conflict sila ng Dashcam so ginamit ko ng unplugged yung dashcam pero meron pa'din.

The speaker humm i'm hearing from the speakers eh lumalakas while driving kasabay ng accelerator. Kay din na try ko yung sa Youtube na ground loop baka kasi kinakapos sa ground kaya sumasabay sa alternator.

i have two front power sockets kasi,

one power socket is plugged into a 3-port splitter:
2 x micro usb chargers for the second row seats
1 x dashcam
I soldered the tv plus power wires inside the splitter

i use the other power socket for the usb charger of the front seats or for a tire inflator

possible sa grounding nung head unit mo ang issue, do you still hear the humming noise on other inputs (radio, video, etc?)

Ah gets so almost the same pala with what you did,... So eliminate ko na sa suspect yung power source cable.

Kaya medyo sure ako na sa RCA cable galing yung problem is kasi sa AUX lang sya may humm, zzzz sound (Normal ang USB, Radio, SD Card)

Maybe the best move for me is to really get a good RCA cable then try ko ulit i-gound ng mas maayos this time.

Will update this thread ASAP para sa iba pang forumers having the same problem.

Thanks alot Sir!

Get a regulated power supply for your TV+ instead of changing the audio cable (i presume is a RCA to headphone jack)

Voltage on the lighter socket varies from 13.5V to 14.5V when the engine is running

If nagpepersist pa rin yung humming sound mo kahit nagpalit ka na ng RCA, bili ka ng ground loop isolator.

Malaki chance na solve yang issue mo.

Got the cable na and try to install bukas. If hindi pa din ma solve will get that ground loop isolator na.

Thank you pap!

Update: a more expensive RCA cable did not work ganun pa din. Maybe next step is to use ground loop isolator.

Question: iba ba ang isolator for audio at for video? Kasi tried to search online and on youtube may recommended sila yung Mpow na brand maganda review & price is okay naman at P650. Kaso baka pang audio lang ito? O pwede din to sa video usage like TV plus.

Sa ngayon ang remedy ko is to lower the treble ng HU sa settings. The higher the treble the more iritating kasi the noise.
