Okay guys, help me out with wiring

[DaJe]

You're right, it's there. It's 9V though.

[Bucko]

Ok then. It was just I had an idea to power it from the speaker.

Actually, it may still work. You were using LED's for the sub lighting weren't you?

If so a change in resistor value could have you tap into that 9V supply and power the lighting from there. You could then run the sub speaker wiring and the lighting power wires inside some sleeving down to the sub and keep it neat.
You'd need to check how much current the power pack can supply (it should say on the power pack itself) and if it's not enough, you could get a better one from an electronics store like Radio Shack.

By doing that, it would keep it all neat and it wouldn't matter where you have the PC placed in relation to the sub, as it will all be coming from the speaker.

4 4inch cathodes, not LEDs.

[Bucko]

Ahhh, ok then. They'll need the 12v then.

Let me have a think about a good way to set up the wiring and get back to you.

[DaJe]

Alright. And it's two seperate cathode units. Two dual 4 inch cathode things.

[Bucko]

Right, if I have this correct, all you need going into the sub box is the speaker wires and 12v power for the 2 lots of cathodes?

I would set up a power socket in the back of your case to supply power for the cathodes.
If you used a 3 pin microphone socket like this:

And a plug and cable to run down to the sub box.

You could even have another socket in the sub box if you liked, so the power cable could be changed depending on how far away the sub is from the computer.
By having that socket in the PC case, you could wire the molex up to it inside the case and have the sub easy to connect or disconnect when needing to move it.
At the sub split the power up into two between the two cathodes.

[DaJe]

How could I wire it so I only need one plug for both cathode sets? I suppose I'd need to wire two male molex together, and then wire a female to them. Would that would fine?

[Bucko]

I guess it depends on whether you want them to be switched independantly or not and where you want the switches.

Do you want them independantly switched on and off from each other?

Do you want the switches on the PC case, or on the sub woofer itself?

If you can tell me those two questions it will help a lot.

[DaJe]

I'd want them on the subwoofer. And even if they had the same power source, they each have a switch. I have two sound activation modules. which also each have a switch. They're what are in that picture above. I guess I'd like the switches for the cathodes on the subwoofer. I wouldn't need the switches for the sound modules on it though.

[Bucko]

Ok, just a couple more questions then.
Do the sound activation modules only need 12v? I can see they say 12v on top, I just want to make sure that is all they need (ie they don't need the 5v feed off the molex).

From how it looks, the molex connector from the PSU plugs into the sound activation modules and then the wires coming out of them plug into the cathodes.

Sorry I'm asking so many questions, but i want to have as much info as possible to get the right set up for you.
