I have 2 10 dvc Image dynamics subwoofer and got a 4 channel kenwood amp just to use for now. I wired The power wire back, (4qauge) Ran a turn on lead from head unit to the amp, grounded it out. The amp turns on and i hooked the subs up and no music? I don't understand i think i ran the wires wrong from the sub I seen on here to run the neg to the postive, Postive to postive on the amp and neg to the amp and still nuthing?
