So bought a double din (Panasonic Strada) to replace my single din on my '94 Lexus GS300, spliced into the old harness and connected them color to color but for some reason it does not want to work while the engine is running, it sometimes works in ACC and the audio is fine, othertimes I get an error message saying weak connection (picture below) it senses a weak connection and just mutes itself. I've had numerous electronically inclined friends look over the connections to see if the solder points are solid and they approved so I am lost on what is happening. When i start the car and the headunit there is a little noise that comes from all the speakers but I know they are connected, then when it fully boots up there is a somewhat loud pop (headunit muting itself/disconnecting from the speakers) and the error message pops up. Any help would be appreciated before I end up letting some hack at Futureshop try to fix it


Not sure what these brown wires are for but guy who installed the single din had these wired to ground
