What are the locations and respective sizes of the speakers used in a 97 Grand Caravan with Infinity Audio ? Thanks in advance...

you have 2 in the dash that are 5 -1/4,2 in the door that are 6x8 and 2 in the rear that are 6x8.i just replaced the the 2 in the dash and the doors with pioneers-5-1/4 for the dash and6-1/2 for the doors.F.Y.I.if your keeping the stock radio be sure not to disconnect any wires other than the ones directly attached to the speakers -you have to unsrcew the wiring harness for the e/q
from the back of the old speakers and find a way to mount the on the old ones.what i did was use the tie strap provided with the new speakers and tie the harness to the mounting bracket on the inside part on the door.
