Hissing sound

[Schroder]

Hi guys

 

Need help on 3 items. I am using the Sony MD-CD set with CD changer and a set of tweeters and original speakers.

 

1-- How do I stop the sound that goes ti-to-ti-to after I switch off the engine? Seems like all Sony has it.

 

2-- How do I stop a hissing sound from the speakers? happened after I changed the orginal Alpine set to a Sony set. Could it be the wiring done wrong? Seems ok to me. Sound test was ok.

 

3-- The set I am using has 2 colors but I forgot how to change them. How do I do that? I lost the menu

Ans:

1. I know the manual got instruction to turn of the sound, becoz I also using Sony.

2. It may HU's grounding not good. Seeking another expert or bring back to shop.

Schroder,

not sure if u got the ti-to-ti-to fixed.

My experience with 2 set of sony also like that. If u read the manual, its a kinda of warning beep by design. In order to eliminate it, u will need to de-activate it by hard wiring. Read ur manual again and it should say something about removing some jumper thingy at the back of the unit... thats wat i remember. Hope it be some help.

hi

 

Do not install noise filter, it is only a quick way out of the problem, the system sound will degrade.

 

Should get the installer to trouble shoot and solve the problem. A properly installed audio should not have this problem.

 

Check out the ICE forum, there are lots of discussion on this topic

 

Cheers

Hissing sound could be the he following:

 

1. +ve cable to close to the speaker

2. the box that connects to the speaker needs to move away from the speaker

 

HU s definetly ok.

 

This hissing sound once almost drive me crazy,, until I move the box but it came back.(cos the box dropped behind my dashboard and i could not bother). Until I did grounding, it all gone away.

You're right, the noise filter may degrade the sound . Delphi ICE forum will be the best place to check

I'm having a different kind of noise coming from both rear & front speaker after I installed the E-Ram . Went to my audio guy, trouble shoot & finally replaced the AMP for the rear speaker (the AMP was about 5 years old) . However, the front still have very soft 'arching' sound whenever the E-Ram is engaged . Haven't finished my grounding job yet, will most likely do it tomorrow & see whether the 'arching' sound will disappear
