Hi,

I got a new stereo in my 9-3 arc.
It is great-great sound.

except... so many problems.
Maybe it's the stereo installer- maybe it's the saab.
New head unit, speakers and amp. There is a hissing noise. There is a whining through the audio system when i accelerate. I lost my parking assistance and blinker sound- he says they went with the stock radio. And the beep when my top is finished moving? Gone. [&o]
i am sad.
Help?
Comments?

 

Amps have a noise filter in them that blocks out the alternator whine. The kicker amps do not. You can purchase a filter just for that purpose at any car audio specialty store. I have also used a bigger cable for the ground wire for the amp. Going from 8 to 4 Gage will make a noticeable improvement.

For the parking assistanceI am guessing something got unhooked but not sure.I can not see the radio controlling the sensors for the parking assistance.The blinking sound does come from my speakers in my 06 so I am guessing it does have something to do with the radio.

Depending on the new deck, some pioneer decks use the antenna line as a 2nd ground. So you can use that line as a ground. The radio is grounded throught the same line as the alternator. As for the amp there could be a grounding issue between the pre outs (rca's) on the back of the deck. Another thing is to scrap a little paint from where you grounded the amp to increase better conductivity.

 

im getting a headunit put in my car on the 4th of february I hope nothing happens to my car...they told me they are going to have to do alot of stuff to my car to get the headunit to work

 

Sounds like a bad ground or termination somewhere. The should be able to fix that.

 

update! they did something wrong then! i have a headunit installed and a amp/sub box and nothing is wrong with my car.r.sound wise or anything
