Can anyone tell me how to take out the trunk liner in a 03 A4. I need to disconnect the alarm siren because it's malfunctioning. the dealer wants 346$ in labor and 349 for a new siren. So if you can give me a part number I would appreciate that as well.

thanks in advance

 

dont kn ow the part number but as for the trunk liner check the diy on a4mods. they show u how to tap into the stock amp and the alarm is on the same side as the amp so u can just follow those instructions.
