Hooked up my head unit today, its some cheap no name unit, not too bad. I soldered all connections to the harness and ran the power to the wiper fuse using the metra harness.
Everyhting works fine, but i have this wierd ticking/beeping noise comming from the speakers.

No idea what is causing it, i held the wire apart to see if it was some kind of feedback or something, but it still does it.

any ideas?

 

Fixed it, just had to reset the unit.
