I installed a

Pac SOEM-4
Axxssess ASWC with all steering wheel contols working
Pioneer backup camera.
Scoche wireing harness

Everything works great. It took me awhile to get everything properly installed( did some dynamating too) but can be done. Was able to fit the PAC under the HU and the Axxess to the side of the HU. tight fit all in all.

I think it sounds much better than the Bose. I have much more control over my sound stage adn my EQ settings. I would say night and day differencees in sound quality. granted I'm not the best audiophile out there, but I know what I like.. I now also have Nav, DVD. adn rear view camera
Without the PAC The volume is very hard to adjust. turning the radio to 7 would blow you out of the car. With the PAC you can adjust the outputs and the volume becomes much more controllable. I did not use the RCAs in the PAC setup. you have the choice of RCAs or just direct wire. While I had the Soldering Iron out I just soldered up all the wires.

I plan to put details of my install up later. If you have any questions jsut reply to this post or PM me

Above is what I'm planning on doing in a couple of weeks, but I'm confused about how all the wiring fits together. It's always been HU -> Scoche wireing harness -> factory wiring for any previous install I've ever done. But where does the Pac SOEM-4 fit into the mix? Does it connect between the HU and the Scoche, or between the scoche and the factory wiring? Thanks for the clarification.

Other Wires from HU: HU ->Scoche Harness -> Factory

Also keep in mind, some wires from the PAC (like power and ground) will connect to the Scoche Harness.

I think someone in this thread said it was not important to have the PAC. I would have to disagree. When I originally had the pack installed I did not tune the PAC(line outs) adn sound became very distorted with alot of white noise in the back round. After I "tuned"the line outs the sound quality is great ( I think much better than factory )
