humming sound when accelerating

[4x4dotPh]

help,

my stereo sounds weird...
the humming sound goes with the acceleration.

what will i do?

[ssaloon]

baka electrical problem yan... shorted alternator or power supply kaya?

[ARB]

its called static. try to check the ground of your sounds system. may mga amps ka ba?

[Ungas]

Or the power cable is closedly placed inbetween with the speaker wires...

[Kicker15]

static tawag dyan. the worst enemy of car audio enthusiasts - try getting a ground loop isolator to help minimize or remove the static

[OTEP]

On my rig, all the power wire run along the passenger side while all the speaker wires run along the driver's side.

This is the proper way of doing it.

If your installer just placed the power and speaker wires alongside each other the you will get static.

or put a FILTER on the power supply, since sabi mo sabay sa acceleration ang frequency ng interference. i suspect that the interference is coming from your alternator. here's how to do it...

simple lang yan, just connect a 1000mf 16V capacitor across the positive and negative supply terminals of your HU. just remember that connecting a capacitor is (+) to (+) and (-) to (-) terminals. you need a 16 volt capacitor because the output of the alternator is around 15.6V, pag mas mababa ang voltage rating baka pumutok yung capacitor.

this solution is worth trying first since a 1000mf16V capacitor cost only less than P20. you can buy this from any electronics store or repair shop.

tell us if it works. may nag-post na dati nyan dito sa tsikot, i gave the same advice. he said he wil try it and posted that he had already bought the capacitor and will install it next day. then he stopped posting, so i suppose the problem was solved.

mukhang ako ata yun a nawala yung nabili kong capacitor, kaya hindi ko pa na try

[odell]

yaman.. may capacitor na siya..hehe/.. penge naman....

[boybi]

P6.00 lang cost ng capacitor

[odell]

ha?. haha..

akala ko un capacitor.. i mena un mga 1 farad.. 1.5 farad...

iba ata un pinaguusapan natin.. san mo pinalitan un sa capacitor..hahaha

[revoGSX]

naging hobby ko kasi electronics pero hindi naman ako engineer... at hindi ko rin alam ang mga computation ng mga voltage at iba pa...

guess ko lang po ito
hindi po ba dapat at least 25volts yung capacitor.. parang ang lapit kasi ng 16volts sa 12v power ng car lalo na at meron din mga power surge from alternator or from the engine? .. konti lang naman siguro price difference nila...

[Dakila7]

it doesn't matter if it's 16 or 25, basta higher than 12V.
