Quick update on progress to date. I removed the four (yes four) amps, equaliser and a mile of old wiring, and purchased an Alpine 103BT from Ebay, complete with Full Speed iPod cable. I managed to identify the original red/yellow/black wires from the loom that I re-connected to the original ISO Connector, and that goes directly in to the Alpine ISO connector - so we have power ! I then purchased an ISO Speaker connector with 8 open ended wires from Maplins and a pack of bullet connectors (male and female) - I crimped the bullet connectors to the open ends, and then plugged these in to the eight original speaker cables on the original loom (they had previously been converted to bullet connectors before). So I now have an original Alpine connector that splits to two ISO connectors for power and speakers. These are then connected to an ISO connector for the power on the loom, and another ISO connector on the loom for speakers. Turn on, insert CD and great sound from the rear and cra**y sound from the front right - nothing from the front left. Much as expected. So it looks like I need new door speakers, and a repair to the coaxial aerial cable, but progress is being made. Any suggestions of 5.25 inch component speakers for the doors ? Photos to follow. Ian
