I successfully integrated the factory deck/CD changer with the EMPEG. The EMPEG was installed into the glovebox, and the factory deck is going into it. I had to change the jumper from 1V input to 4V, but it works great. I had to install the A/D/S/ P840.2 8 channel amp to run the factory HK speakers, and it sounds better than stock. I do however still have the speaker pop when turning off the car, and when I install the included grounded RCA the system doesn't sound right. So I am going to have to find a different way of taking care of that problem. But other than that, it sounds great. If anyone has any questions, you can privately email me as well.

Thanks Hugo for such a remarkable product.

Is that jumper internal?

Yes. There are two next to each other. But be warned, that if you open the empeg, you void any and all warrantee's.
