Never have found good wiring diagrams for stereo's. Bought them and color codes didn't match. I have mitchell and alldata at work, they don't match. I wire them in with a volt/ohm meter. I find B+, Then hook ignition the the heater control wire. Ohm out the speakers. Thing is, you have infinity. You'll have to find the amp and cut the speaker wires and patch them there also, first. Just a note.. All speaker wires are twisted/paired wires. Cut the tape back 4 to 6 inches to find them. Another note. The speaker wires from the stereo to the amp will be a set of colors. From the amp to the speakers will be different colors.

You can use the amps if your replacement speakers have the same or higher resistance as compared to the original speakers.

Sounds like your Gr Caravan has the premium sound package. You likely haven't hurt anything - but you may need to modify the wiring a bit. The speakers have a tweeter speaker in the center of the main speaker and the wiring goes through that. However, it only worked with the premium package. Go in to the speakers and move the wiring connections from the tweeter to the main speaker. Your other option is to replace the speakers.

I had this same problem. After reading other ideas and some trial and error, I finally got it. Most Caravans have an Infinity system (the speaker grill will say Infinity on it) ,which uses an amplifier to run the door and rear speakers. I had to ground the clip wire that was originally attatched to the strap ground on the factory installed radio. Then I also had to hook the wire on the new radio for power antenae (blue and white on my unit) to a blue wire on my new harness. This wire came from the last wire of 7 wire harness that had the other 6 wires for speakers. The original wire appeared to be green/red on my vehicle. After I connected both, the speakers cameon and sound great again

Hi,

Either the radio's output ICs are fried or speaker/wires needs to be checked.

Incidentally, there are some higher end versions that has an Infinity Amplifier (P/N: 56038407AD) powering the speakers and not the radio (alone). If so, this amp needs a trigger on from the head unit to work and therefore, the trigger wire/connection must be checked. Otherwise, it may likewise require an internal check.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.
