hi bro,

me no pro and have no knowledge at all in ice..
recently i changed my car hu to oem china dvd/gps, for the sake of look.

i discovered, when i on the unit and while i did not play any music or video, it will have psssssss sound from my front speaker. are those sound called as noise?

if i mute my speaker, the psssssss sound gone. when i play music or video, the sound is not noticeable.

so, issit common? or setting, wiring or unit problem?



thanks!

check ur grounding 1st

what issit? the hu is plug and play

Not grounding issue but the hu itself if according to ur explaination

is amp installed?

nope nothing installed..removed the stock hu and replaced new..no install other thing.

Should be HU problem.

if so need back shop to check later..
could it happen if i set my treble too high? max.
bass only +2..

Irrelevant

just now i tested..
my bass was earlier +2 and treble +7

try to lowered down, still got sound but getting softer as the adjustment decrease.

the only way to have no sound is the default which is bass+0, treble +0.
either one +1 will also cause the sound to appear.

is this common?

You tested yourself it is HU problem.

hu problem or not, i google and i found it quite common. ill just set it to default then.
thanks a lot for those who share their expertise of showing me root of the problem.
i will be glad if i can get a solution.

I second that.

TS, it's your HU for sure. I'm owning one China HU too, same issue.

yes it is common for that kind of HU...dont worry.
u can try noise filter though.but since the noise is not noticeable during playing music then just leave it la hehe

I kena like this before.4-5 players tried on my car.all not cheap players.got japan double din,alpine,etc.but all the same.
so i straight suspect my car wiring.but then,until now tarak settle..give up liao.

ya the sound is very very soft and not really noticeable..
if aircond or engine on cannot detect at all..so i guess i either dont increase the setting or increase it and let it be

ty ty

you could always bring to howie. you have the dough to spend on "not cheap players", why cant you just spend a bit more on labour charges? (in some cases, he also dun wan charge me for very minor stuff, feel bad la )

U think i'm rich ah buy all 4-5 "not cheap players"? all borrowed laaa..want to pay for labour charge also can't afford.

he also got used HU/test unit HU i believe. point is you never really asked/tried.

I agree
