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. 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 assistance I 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
