I have bought the above and am trying to fit a double din tv screen.

A local fitter has said the reason i cant find any speaker wires is because there must be an amp somewhere and the fibre optic plug from the original stereo is going to it.

It seems i will need to run new wires to the amp for all the speakers then bypass the amp and pick up the original speaker wires there.

Does anyone have a better idea? and more importantly where the amp is located in the car??

It's in pieces in the garage right now so any help would be much appreciated.
