Does anyone kow how to tell whether your subs are dual or single 4 ohm dvc? I know my subs are 4 ohm but how do you tell if they are single or dual voice coil
single or dual coil makes no difference to the sub's performance. it's strictly a matter of convenience for matching the speaker load to the amplifier you choose.
you just need to figure out the following: how many subs you want to run per amplifier what options you have for coils on the subs how much power each subs needs
then you can match that information to the proper amplifier
