How do you hook up 2 15 inch cvr to 1 ohm

Hello juanelreypla,

If your CVR's have dual 2 ohm voice coils, they can only be wired for 0.5 ohm, 2 ohm, or 8 ohm final loads.

If they have dual 4 ohm voice coils, they can be wired to a final load of 1 ohm. Wire the voice coils in parallel and then parallel both subs. Like the diagram in Wiring Option #1 shown here.
