As far as I know it's whole purpose is to power the factory Bose system so that you are not having to start over from scratch.

I installed that the PAC box and while it's not great, I don't think it's any worse than the factory sound. I also adjusted nothing on the box.

I've read a few articles online and on YouTube with suggestions on adjusting the PAC box and it does sound like a total PITA to get right.

You may want to double-check if the BLUE-WHITE wire from radio was connected to the BLUE wire on the PAC ROEM-VET1. If it was wired "blue-white" to "blue-white" instead, your door subwoofer amps will not turn on, resulting in no real bass.

Also, take a look at Fuse 28 and Relay 45.

This is the video that I followed to build my wire harness. It has a ton of great information in it on this very install.

As I mentioned above in Post 3, the correct wiring is BLUE-WHITE from radio to BLUE on the PAC ROEM-VET1. You probably meant you got blue-white to blue-white and that's why the subwoofer amps were not turning on, right?
