I have an "original sub" with factory installed dual voice coil speaker and related crossover network purchased in 1995. I want to remove the crossover and wire the voice coils together so it can be driven by a single dedicated amplifier. Labeling on the back states that the "original sub" has an impedance of 8 ohms but doesn't say anything about the dual voice coil option.
My question is, are there two 4 ohm or two 8 ohm voice coils? It would be nice to know whether I need to hook them up in series or parallel.
