i recently bought a 92 740 wagon and upon installing a aftermarket stereo noticed there is no wires to the door speakers but a lead from the factory radio for an amp i have searched the whole rear of the car and under the seats and im not able to find it and only having the 2 speakers in the dash is rather crappy anyone know where the elusive thing is located trying to avoid running new wires to each door if i dont need to.

 

delete plz
