hello everyone. am replacing the front and rear speakers and adding a 10" sub under the passanger seat (TS-SW1041D pionner, yes it should fit). powered by 2 separete amps located in the trunk. I would have to run speaker wire from the original deck (as I have navi and definatelly want to keep it) to amp #1's speaker level input in the trunk, then back to all 4 speakers. The sub will be powered by amp #2 also in the trunk which receives audio signals from amp #1 through an RCA pass through connector.

my concern is, will this mess up the ANC??? or anything else? what else should I be aware of? any ideas? suggestions?

lots of wiring to do, has anyone done anything like this to a hybrid with navi and voice activated commands and replies?

also, where can I find detail instructions on taking the dashboard apart, door panels, etc?

Thanks!!!!!!!!!!!!!!!!!!
