12 jl w3 airspace - Jl Audio 12W3v2-D2 Car Subwoofer

SOURCE: trying to find out wat the watts are on a jlw3 12 and a jlw0 12

The JL 12W0 needs 125 watts RMS. Sealed box it needs 1.5 cubic feet. Ported it needs 2.5 cubic feet.
The JL 12W3 needs 300 watts RMS. Sealed box it needs 1.25 cubic feet. Ported it needs 1.75 cubic feet. I wouldn't suggest running these subs together.

Take an OHM meter and measure the resistance on both the positive and negitive leads. It should read 2, 4, or 6 OHMS. This depends on the model either a D2, D4, or D6. If you read that reading correctly then see if there is a capacitor located on the the cone itself or in that area. If it is not visible then that would mean that it is located inside of the magnent area.

wire the sub in series it will give you best bang

SOURCE: is a 15 w3 d-4 better then a jl audio w3-d2

Hello,

All of the JL W3 subwoofers are essentially the same. The "d2" and "d4" suffix refers to the voice coil configuration. "d2" = dual two ohm coils, "d4" = dual four ohm coils. Depending on the number of subwoofers in your system and the amplifier(s) you are using to power them, one or the other of the configurations may be "better".

Generally, you want to have the load on your amp to have the lowest possible impedance consistent with the amps capability to operate properly with that load. It's normally referred to as "impedance matching". Greater power (watts) is produced, and louder sound, when the amp can deliver power at a lower impedance.

If your amp is only capable of supplying power at 4 ohms, you want to make sure that the configuration of your sub(s) represents a 4-ohm load. If the load is higher, say 8 ohms, then your amp can only deliver about half the power of which it is capable. It would be OK to run them a 8 ohms, but they would not be as loud. On the other hand, if the load was lower, say 2 ohms, your amplifier would soon overheat and go into protect mode.

So the trick is to first decide on how many subs you want. Then choose an amp/sub combination that "matches".

The DVC or dual voice coils just gives you more options in selecting and configuring. Say you want 2 subs and you are going with the 15w3 d-2. Your amp is the JL Audio G-MAX monoblock. The amp puts out 1200Wx1 Chan. at 2 ohms or 600Wx1 Chan. at 4 ohms. You would wire both of your subs voice coils in series making each sub 4 ohms, then wire the 2 subs in parallel to your amp making the final load 2 ohms, the best "match" for your amp.

Hi their the best link ever to wire up subs is this:
