Well this morning I decided to challenge installing my new speakers in my front doors. I am impressed that I got it all done without breaking anything lol! It's quite simple really with the correct adapters and mounting brackets. I am super happy with the sound improvement as well. I bought the infinity primus pr6512is. I have the fronts installed and I bought the rear door speakers but am afraid. I have the roller shades in the back and don't want to break them lol.
