I am getting ready to switch my cheap jvc with my xm pioneer head unit into my 93 4 door lx

I am just wondering if anyone can give me suggestions on how they ran the antenna through the car.

I imagine the best way would be through the back window, to the front.

Wondering how difficult it is to remove those chrome pieces that surround the back window. Yes, they are all still on, and still firmly intact.

Any suggestions, diagrams or videos would be greatly appreciated.
