I assume you have a GTS because you won't be happy with a sub in the trunk of an RT. I ended up putting my sub in the passenger foot well. But to answer your question, I think you can trace back the electrical from wiring that goes into the trunk and use the same hole. I had a stereo amp in there (that I believe was stock?) and I went through the same factory looking hole that it used.
