    How to wire 3 JL 12w3v2's?

    I have 3 12w3v2's (4ohm) that will go in a toyota truck (extended cab) in a sealed enclosure firing down. What is the best way to wire them?

    Thanks in advance.

    What amp?

    For a mono amp, your options are:

    Subs in series (8 ohms per subs), parallel to amp: 2.6 ohm load
    Subs in series (8 ohms per sub), series to amp: 24 ohm load
    Subs in parallel (2 ohms per sub), parallel to amp: .6 ohm load
    Subs in parallel (2 ohms per sub), series to amp: 6 ohm load

    You wire the subs in series for an 8 ohm load per sub, then wire them parallel to the amp for a 2.66 final ohm load. Remember:

    Parallel wiring = impedance of coil / number of coils
    Series wiring = impedance of coil X number of coils

    So the for subs in series you get: 4 (ohms per coil) X 2 (# of coils) = 8
    Then parallel to the amp you get: 8 (ohms per sub) / 3 (# of subs) = 2.66

    Hope that helps

    Thanks. It's becoming clearer. So even though this is a 4 ohm sub (that's what's on it), it can handle the 2.66?

    Subs don't "handle" the load, they create it. The amp is what has to be able to handle the ohm load.
