2005, Chrysler Grand Voyager Limited, 2.8 L CRD
In diesel models here, you cannot find a Name Brand Speaker (NBS) relay in the fuse and relay center. On the contrary, in gas models, there is an NBS relay there. And; you can easily bypass that relay, if so equipped. There are forums here explaining how to bypass the amplifier. It's the easiest way for gas models. When I had a 2001 Chrysler Grand Voyager Limited, 3.3 L; I took the advantage of mentioned forums and bypassed the relay. In other words, amplifier. In diesel models, you have to do some cabling work to bypass the amplifier. By using the service manual, you have to find the related speaker cable colors already coming from the factory plug, as well as amplified outputs from the amplifier. Just connect the relevant cables to and from the amplifier by means of a hand made harness and that's it!. You can connect dash speakers from the relevant door speaker cables like you will do from the rear side panel speakers to the rear tweeters. Some may prefer installing new speaker cables out from the aftermarket head unit instead of jumping the cables but, since it's too much work, I don'take that...If you go to aliexpress and type "chrysler voyager android", you will get them, but seller says "if navi and amp oem system, do not buy"
