what wires do i use to bridge subs together?
Use 12 gauge speaker wire, anything else will cut down the signal. The bigger the wire the cleaner and stronger signal that will transfer from one to the other. Besides, subs are not like compnent speaker or 6X9 speakers, they need a good signal to produce a quality sound. Use the 12 gauge wire to wire up your voice coils, and run 12 gauge wire from your amp to these subs as well.
12 awg twine is superb....yet i do no longer understand your question. Are you attempting to parallel or sequence the voice coils? Paralle. tie the two together. constructive to constructive. detrimental to detrimental. which would be a 2 ohm load. sequence. in basic terms run the bounce twine from constructive of one coil to detrimental of the 2nd coil. which would be a 8 ohm load. Assuming the coils are 4 ohm..wish that enables.
