Don't use any tapping . Get a 6 channel amp and Technic harness.
Or get a Technic Harness a forget about the rear channels.

The output of the Head Unit in the Hi Fi system uses differential outputs
which means the there is a a plus and minus signal with no common ground.

You have to have and amp capable of taking this kind of signal which is essetialy
a reduced speaker out.

You could tap the Inputs to the amp but I don't know why you would do that since
you have to disconnect the existing speaker wires anyway for the amp to feed
those locations.
