first off it wouldnt be a good idea to turn on your system too much if you havent already, having only one vc of a dvc sub is not good for the sub.

This is how you should have you subs wired.

Also I hope you have your power wire and ground wire run to the amp and fuse correctly

wiring it that way, is the correct way, using only one of the two voice coils on your subs with damage the subs. But yes this should effectively give you a 3db increase (aka double your sound)
