Wiring subwoofer Audio connections

Hey guys I’m new to this whole “new car” and the modifying of it. I’ve got a 2023 Volkswagen Jetta S and I was wanting to put some subwoofers in the trunk I’ve wired many subs now but all I’ve ever used is an after market radio for the audio signal and I want to keep the factory radio in this car and I want to be able to make the car stock again if I go to sell it so I don’t want to cut into the factory speaker wiring to get audio signal. So I’m wondering if the their are any adapters or anything out their to make it so I won’t have to splice into those wires

thanks in advance 😁
