They are correct. The car uses a CAN (controller area network) bus. In addition to supplying audio signals to the amp, the head unit talks to the amp over the CAN bus. Without this communication, neither head unit or amp will work. Even if it could work, it would be less than optimal to use with the type of unit you've put in. The speakers might not be matched that well either.HEMI4ME? said:OK, quesion, is anyone running an aftermarket deck with the factory amp and speakers? I mean not using the power from the new deck... If so, can you tell my how the shop or you wired it to work? My shop is saying that they can not use any type of adapter because it is some sort of "data buss" system, and there is nothing made to integrate an aftermarket deck.
Thank you for you rreplies!!!
