Hi Thanks for reading. I have a 4 ohm sub with a dual voice coil. With both coils connected in parallel the nominal impedance is 2 ohms and the minimum impedance is one ohm.
My amp can handle a 4 ohm nominal speaker, so can probably go down to a minimum impedance of 2 ohms.
Can i place a high power one or two ohm resistor in series with the driver to make sure the impedance is not too low which may damage the amp
I was told years ago that resistors add resistance and not impedance, so do not raise the total impedance the amplifier sees, what do you think
