humming sound

**coiter** · April 1st, 2009 04:52 PM

ano ba dapat icheck ko?

ganito kasi, pagmatagal na kong nasa daan, nagloloko yung radio ko. bigla na lang nagkaka humming sound na lumalakas pag tumataas rpm or bumibilis takbo. then may mga parang static, yung tipong sound ng nagsspark na wire, pero galing sa speakers. pag in-off ko yung radio, wala nang mga tunog. pero pag on ko uli, andun na naman. pagnapahinga na yung sasakyan (off engine), pag start uli, nawawala naman yung abnormality. ano kaya ito?

TIA

Static sound yun sir, ganyan din sakin dati. newly installed ba ang sound system mo?

may ganyan ding sound yung sentra namin dati. ang narinig ko lang sa papa ko, static sound nga raw. pero nabenta na kaya hindi ko alam kung paano na-solve, or pinabayaan nalang ng buyer.

Its coming from your radio. Try to ground properly your radio.
Separate your signal wires from power wires.

may ganyan ako naririnig pag naka plug ang cellphone charger ko, humming sound galing sa radio, am lang naman.

subukan mo tanggalin kung ano man yung nakaplug and observe.

how do I know which is the ground wire? I'll try to trace the power and signal wires to check if there's contact.

wala naman akong pinuplug na kahit ano sa cigarette lighter. during daytime radio at aircon lang naka on. ang weird nga kasi pagmatagal na kong umaandar lang sya nangyayari.

hindi sir. lumang luma na (11 yrs). I think stock pa sya save for 2 additional speakers sa rear na tinanggal din ng dating owner. simpleng HU + 2 front door mounted speakers + cd changer lang ang setup.

thanks for the replies guys! keep em comin'!

sakin ang naging solution nilipat ko yung location ng ground

Minsan kailangan lang kabitan ng relay mawawala na iyon. May kaibigan ako nakabili sa Blade ng grounding kit. Nakatulong din iyon.

sir...try nyo na mas malaking gauge ng wire sa negative and bolt nyo sa body ng oto. lihahin nyo muna ung surface bago i-bolt para malakas contact.

hmmm para syang alternator noise.. usually nangyayari sya pag magkadikit yung power cable and RCA (signal cable) ng amplifier..

try to fix or unclutter your radio wires baka nagkadikit dikit na kung wala naman po kayong nakakabit na amp.. HTH
