My friend is installing his eclipse avn52d headunit in his 05 hyundai sonata.
I've had a little more experience with it so I was helping him. We got everything squared
away and now came time to turn on the car and test it. The headunit came on
but there was no sound coming out of the speakers. I double checked wiring.
Still nothing. Went to the biggest audio shop around town and they told me to check
a few things and I did that still nothing. They said the car might have a factory amp
and that is why the speakers arn't working because the amp isn't see power, which made sense
but when I did what they told me it didn't work.

I am trying to search the internet and see if anyone has had this problem.
Any input is really appreciated. Thanks

 

I had the bog-standard kia/hyundai am/fm/single cd unit and I did not have any problems when I switched to my current Kenwood unit.
