I recently had the original radio in my '65 Fury III convertible rebuilt with FM, aux input, and Bluetooth capabilities. I replaced the old cracked speakers at the same time with new speakers designed for stereo sound. It sounds amazing, but the car won't start with it hooked up even when the radio is turned off. I'm not getting spark at the ignition coil, and I'm getting about 7.5V across the coil when trying to start it. When I unhook the wiring harness for the radio, it starts right up. Has anyone has this experience or any ideas on how I can address this?
