Bronze Member Username: Jandrew007Suwanee, Ga United States Post Number: 12 Registered: Dec-07 | I am just getting back into car audio after a 10 year lapse and I used to buy jl audo 10 and 12w6's with the dual 6 ohm voice coils. How would I get to 1 ohm load on the amp with 2 12" DVC speakers and how do you figure the impedence? I don't even know if it is possible but am asking. Thanks! |

If you wire them in parallel (pos to pos and neg to neg), you'll get 2ohms. If you repeat the same process on the 2nd 4ohm DVC sub, you'll end up with another 2ohms. Now if you wire the 2 subs in parallel again (pos to pos and neg to neg), you'll end up with 1 ohm load. The rule of thumb is, every time you wire the VCs in parallel, you half the resistence, if you wire it in series, you add the total resistence. |
