Proposal for a sticky in this "Off Topic Tech" subforum.
What's your infotainment setup? What plans for modding or replacing your setup do you have?
Your setup/plans do not have to be "eco" for this thread. Maybe you added a huge subwoofer. Maybe you UPPED the electrical draw of your car stereo in general. Or maybe you deleted all or part of the OEM system to save weight or power. Got an arduino wired in somewhere? Or you might have added or deleted sound deadening. Maybe you decided to carefully design a modest but good-sounding system. Maybe you made an Android tablet into your car's headunit. Maybe you added an aux port or bluetooth by janky wiring or proper wiring.
Tell us about it. How did you do it? Share pictures.
