my au111 has factory in dash 6stacker, bought amp for car with av conection to stereo only. f**k ford stereo doesnt have that type of connection.any other way of wiring it up?
any direction would be good

only way is to use line level convertors

to go from teh speaker outputs to the converts = rca leads then to amp

i have done this and sounds quality was fine for me but for others may not be
