Must be that you are using the old speaker wiring that is COMMON GROUND wired. Aftermarket Radio will not like that sort of wiring for speakers. You need to run new wires at least to the rear speakers or I would do all 4 just cause the wiring is old.
Please visit my bio for access to my Saturn help site. here you will find a diagram of the factory wireing to assist you in installing your aftermarket radio.

To wire the steering wheel controls for a Mazda 3 after installing an aftermarket audio system, you'll need a compatible steering wheel control interface, such as a PAC SWI-RC or similar. Connect the interface according to its wiring diagram, linking it to the aftermarket radio's remote wire and the vehicle's power and ground. Follow the instructions to program the interface, allowing it to recognize the steering wheel button signals. Finally, test the controls to ensure they function correctly with the new audio system.
