Hi I'm installing a tablet to replace the cdr-220 so far I found all the pinout connections that I need but have a question:

The Ipad 3.5mm audio cable has 3 wires (left +) and (right +) and a common ground, the stock nokia 4x40w amplifier has 5 wires to feed audio: (right front +), (right rear +), (left front +), (left rear +) and a bunch of grounds joined into a common ground, do I connect both left + to the 3.5mm audio left and the two right + together to the 3.5mm audio right and the ground to ground or do I only use one of the left and one of the rights and ground, I have been reading and people that tap an aux into the stock systems only connect to 3 wires and not to all 5?

I hope the above makes sense

Thanks for any help
