I want to put in new radio

Make sure you have the correct wire harness and all speaker wires are hooked up. If so make sure your ride doesnt have a factory amp. Some bose or infinity factory sound systems have a factory amp that you may need to bypass

I need the wiring diagram for a infinity model h285jcbl 2003 car radio and amp

everything depence of system you putting in your car if u have no amplifire you connecting the speakers to radio as they marked i you putting one in, your speakers wires goes from amplifire to speakers there is no diffrent way of connection. also the diameter of your wires have to be adekwate to power u going to have in your system for optimizing the sound quality let me know if this help ya

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.

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.

You most likely need a new radio. They go bad all the time in the Chrysler/Dodge/Jeep. Don't know how many of them I have replaced.

Did you use a special wire harness? GM connected some computer system wiring with the stereo system, so if you replace this, there will be no chime when you open your door with the headlights on or keys in the ignition...and some other warning stuff. This special harness can be bought, but it is expensive (around 80-150$). Go to electronics store and ask for one. Anyways, hope this helps.

HI there... It would be a wise idea to get the special wiring harness for you aftermarket radio. There are several reasons for this. 1 is that it will make your installation a lot easier because it will plug right in to the factory plug and all you have to do is wire the radio to the wires on the new plug.
2) the newer vehicles have the radios wired for lights when you turn your headlights on. aftermarket radios don't always have that. also your stock radio probably stays on when you turn your ignition off and goes off when you open a door. the aftermarket radio is not set up for this and could cause electrical problems if not hooked up. to avoid any nasty electrical headaches I would advise getting that special plug. Hope this helps you out

Try halfords they do a lot of car audio conectors.You give them the name of of the product your fitting and the car you want to fit it in.usually a universal plug is offered.plug it in your radio then into your loom and away you go.No additional wiring no mess.Usually costa around £7.Hope this helps.
