So I recently hooked my xbox 360 to my alpine headunit, but small issues that are bothering me. I don't think it's my power supply, I got a 300Watt modified sine wave inverter and it powers my xbox legit, connected to my battery and everything, I have weird lines that run through my video, it's someting i can live with, but if it's something small I can fix that would be good to, also for the first 15 minutes on it makes a buzzing kind of a noise through the speakers but it goes away. Is their a better way to hook my xbox up in my car?
