audi a4 b5 woofer + fix







If subwoofer and rear speakers not working (avant version):
While radio is ON check if ther is 12V as red marks show. If so, check if there is a short like yellow marks show, if there is no short while 12V is in place, that means, relay is not working, change it or make permanent short between yellow solder joints.

  1. if you look at the last image, above the "t" in "Skrat" there are two pins coming through the board that have been bridged with solder. Can you explain what you did there because my board doesn't have a soldered connection there and I was wondering the purpose of it. Thanks

    1. I DO NOT REMAMBER I TRY PROBABLY SOMETHING ABOUT SHUTING DOWN OF WOOFER 15SECONDS AFTER RADIO POWERUP, BUT IT DIDNOT HELP, PROBLEM WAS AT RADIO DIAGNOSTIC CIRCUTE, WHICH DETECT SHORT TO GROUND ALWAYS AFTER 15SECONDS ALSO WHEN WOOFER WAS DISCONECTED FROM RADIO SOCKET
