A friend asked me to help me help him out installing his aftermarket head unit into his 2000 caravan. No problem removing trim and radio etc. Have the harness etc. all plugged in. I'm almost positive it is not an infinity sound system but it does have a connection for an amplifier which is green and black. There are six speakers in the van. Two on the dash, two in the front doors, and two in the back. The two in the door will not work. I have the ground connected to a braided silver cable which grounded the factory stereo. I've tried a few combinations with the remote wire with the amp etc. Checked fuses. Any ideas?
