sry man, but if you have a dvc sub, then when you run near half power to it on a good hard hitting song, the sub wont last long, it really depends if you wire you speaker paralell or other ways when it is dvc to make it 2 or 1 ohms from a 4 ohms setup. if you really have any questions you can always go to crutchfield.com for specifics on the wiring bc they have diagrams there. i persoanlly have a kicker compvx4dvc12. i have it wired down to 1 ohm and on a 1k amp it hits so hard i can't stand it, but its wired to its peak ccont. running power
