I’m not too sure this will work, at least with the stock speakers. There is a capacitor in series with the dash speaker to protect it from lower frequencies. As the multimeter applies voltage to take a resistance reading, it will charge that capacitor which will cause the capacitor’s resistance to approach infinity - this effectively removes that speaker from the circuit. Since the door speaker does not have a capacitor, I believe you may have been just reading the 4 ohms through that. Once the circuit is running under AC from the amp, it behaves much differently though and should be closer to 2ohms impedance.
