Tony You can go about this in two ways. One is to have your speaker re-coned. Here in Colo Spgs its about $ 40 per speaker. Number two is to go to your local Pick & Pull Auto Recyclers and get a speaker from any Chrysler/MoPar product. They have not changed the ohms since ~. The dash spkr is round and the spkr on the rear deck is oval in your vehicle. Caravan rear....Chrysler/Dodge 80's sumthin door spkr's are round, but a slightly smaller diam. You can make it work. The rear deck spkrs for the same vehicles are oval. They sell for $3 bucks per spkr and can be exchanged if you pick a spkr that has been in a vehicle with no windows and it may have gotten rained on once or twice. GM and Ford spkrs each operate at differant ohms. Rodger & Gabby
