So i'm going to put a sub in my car, already got the amp and the amp kit. However how do you run the power wire to the trunk? I can't find any holes. How did you install your amp? Let me know thanks.

I have the 1st gen TL 2.5.

 

With questions like that, I would highly recommend that you take it to a professional to have it installed. They will be able to run the wire properly, make sufficient connections, and set everything up correctly.
