yea,,, no need for plugs,,, just start from one sub,,, dual voice coil, start at one voice coil, postive to other postive on that voice coil,, same as negative... 1 sub done,,, now run the postive from the first sub over to the first postive on the 2 sub, then run the postive to the 2 voice coil. same as negative again, then on the last voice coil, run wires to your selected source
