Jishnu, do not add this sir thing next time buddy. Call me Yashik/yb/paddleshifter etc. Well, Emotion pack can be AMPed as well. You can take speaker level input for a 4 channel amp from the front speakers. Then you can connect front comps with amp while allowing rear co-axs to be powered from the HU itself as in stock situation. Rest 2 channels can be bridged to power a sub as per your liking. Problem is that we need to feed some input to the amp so that it knows when the car is being switched off so that it can switch on-switch off along with the car. If not done, it will keep itself switched on 24x7 leading to battery drain. I think Viny and Jayadev had once discussed a solution for wmotion pack and a wire can be plugged into the same aux in socket along with the blue and me connectors. Another option is to take power from ACC but no one here in Chandigarh knows how to do that without splicing or cutting a wire.
