One of these aftermarket Android system with screen, do they properly connect/power to my Bose speakers (have center speaker) and sub? I really don't want to lose out my Bose sub or having to add a separate amp to power crappy Bose sub, it isn't great by far but better than zero bass.

Anyone installed one? I hope they can at least last 3yrs before it stops working.

For my own knowledge, which unit feeds power to all the speakers? I know Bose sub has an amp in the trunk that I had to replace when it went bad, I assume the AV unit just have a signal feed to the Bose amp.
