I want infoon adding a suba nd amp to OEM setup alsooo, please!!!

you can do it quite easily. I'm pretty you can just wire it in without anything special. I would put my sub and amp in my s4 but i think it will overpower the bose speakers.. 1000rms :)

check the DIY section - the info is in there on getting the interface for the OEM system (although you'll lose your changer), and on how to tap the OEM amp's signal to feed to a sub amp.
