hey guys, so i got a vellfire that comes with a original factory amplifier that drives my home theater speakers. i think around 10 or more speakers...im not sure. the thing is im planning to change my headunit to an aftermarket. im cracking my head how do i integrate the amplifier into the aftermarket headunit? correct me if im wrong, does the rear camera signal also goes into that processor thinggy?

thank you guys for the info. From what i can summarize, i have given up trying to get this integration to work. Firstly the cost is to high and the rework is too big of a mess. Im just afraid the complication might lead to other parts of the car. Nevermind i shall just settle with the current setup. if i were to add a new system while bypassing the oem factory system which is still working fine, then it becomes redundant. Its not like i can transfer the oem system to another car or something like that. it becomes no value. anyway thank you very much for your input guys.
