What is the difference between a subwoofer of one coil or those with two coils? My brother is donating me an amplifier with five channels. In the car audio forum recommend me to buy a sub with two coils. If my amp has only one channel available a double coiled subwoofer could be used? If so how can I connect it? If I connect only one coil of a double coiled subwoofer, the sw could be damaged?
Best regards :)
