I have googled for days and have had no definitive success for an answer or maybe I just can't seem to google properly.
I am going to gut my double-DIN and mount a 7" android tablet (custom homemade mounting and software), raamat, 4ch amp and 4x 6.5" door speakers (alpine). As far as installing the stereo and its components, I have no issues except for one: tablet 3.5mm output voltage. As I plan to not have a HU at all, I'm not sure how to get the voltage to a proper readable level for the amp to get the most out of it. Any suggestions would be VASTLY appreciated and thank you in advance.
