The resistance of the voice coils is the same and would be the same if another amp is added. Both amps together will still se the same load you have now as the voice coils haven't changed.I have two single voice coil 2ohm twelves running on a JP8 now. I want to get another JP8 and strap them together. But I'm nervous about the final ohm load the amps will see. Anybody think I should try it or just get a bigger amp
Yes, but when you strap amps each one "sees" half of the total impedance.The resistance of the voice coils is the same and would be the same if another amp is added.
