How to wire 3 JL 12w3v2's?

[SirSteve 10+ year member]

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

Amp - a JL Audio 1000/1.

Go with the first setup I listed

Is this in series? 2 ohms? Sorry, I am new to wiring...

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.

ahh.... so true. I used my words incorrectly. Thanks. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
