How to wire a 12V DC set of CCFL lights, into my car audio system

[Gobble45]

Hello Everybody, this is my first time here at Electronics Point.

My question today:
I want to wire in some Cold Cathode Lights, to my Sound system in my car.
The diagram is here:

And is also uploaded with this post.
What i want to be able to do is where the "?" (question mark) is on my diagram.. i want that to somehow wire in with the subwoofer/amp circuit. and again but just simply to the Head Unit power. ( i have switches etc for power on/off)

currently the 2 CCL (Cold Cathode Lights) connect to a power converter box (about 1" x 2", very small so easy to hide) and then that connects out to either a "Molex male" OR "Molex Female" OR (forgive me as i dont know a correct name) what looks to be 2x 2pin female. (see this image for verification: http://www.google.com.au/imgres?q=2+pin+connector&hl=en&safe=off&gbv=2&tbm=isch&tbnid=4EHAZkcguvHc9M:&imgrefurl=http://www.cmsnl.com/products/2-pin-connector-set_31107/&docid=D_Th_UajeS3QhM&imgurl=http://images.cmsnl.com/img/products/2-pin-connector-set-type-250_big31107-01_5f45.jpg&w=1024&h=768&ei=yZGWTuT2GKbWmAXrouGfAg&zoom=1&iact=hc&vpx=176&vpy=151&dur=3034&hovh=194&hovw=259&tx=172&ty=108&sig=104887078416351946204&page=1&tbnh=142&tbnw=174&start=0&ndsp=45&ved=1t:429,r:0,s:0&biw=1886&bih=958
)
My god that URL is long :/ anyways...

I cant really give much more details, but dont hesitate to ask specifically, and i may be able to answer.

These are the lights:

Yes i realise these are meant for a computer..

THANKS IN ADVANCE, James

EDIT:
The 2x 2pin cables that i was unsure about.. they connect to the switch provided.. so basically i need a molex to something?

hi James
welcome to the forums

I havent played with that style of lamp other than for LCD panel backlighting.

I assume you want to have the light from the tube pulsing in time to the music ?

Yes, this is correct.

I have spent hours searching for a solutioon.. and i cannot find anything :/

How to wire a 12V DC set of lights, into my car audio

Hey guys, similar to my last forum post, but a different question.
I want to wire in 2 ColdCathodeLights into my Subwoofer/amp circuit. so that when the music plays, the lights flash.
the circuit goes like this:
yellow cable (not connected to anything at one end)
to
switch
to
red cable
to
inverter box (which sends power to 2 of the Cold Cathode's)
to
black cable (not connect at one end)

The black cable is GROUND
and the yellow goes directly to a 12V DC outlet.

but i want this to be wired into my subs :/
how can i do this?

 

[Resqueline]

It all depends, on conditions (music type), items, and desired results. I won't claim to be able to provide the best answer.
Why don't you start with defining your electronics skills/experience? Are you comfortable soldering, making small transistor circuits for example?
I merged your two threads btw., since I was unable to distinguish the difference between them.

 

[Gobble45]

The conditions: Hardstyle, Heavy Bass, Dubstep, Trance, Dance - Basically anything with bass
My electronics experience: not much, i installed this whole audio system, with little help from my dad. but am comfortable Soldering.
I have now a new question.
i have worked out my previous 2 questions, and this is still in relation, but more electronics than the installation of electronic equipment.

That, is a diagram of what i have currently. but because the subwoofer AND lights are on the 1 circuit. the sub is not as poweful. and if i turn the switch OFF the sub stops..
is there anyway to keep the lights "Flashing" in time with the subs, AND make the sub as powerful as it was without the lights.
??

Connect the output of the audio amplifier to a full rectifier diode bridge and feed the lamp with that, observing polarity.

If the audio signal will be very loud, insert a resistor in series choosing the proper value that at full volume will not produce more than 12 VDC.

 

[Gobble45]

Could you possibly explain that a little better, maybe even a diagram?

 

[Externet]

Hi.
Am unable to post diagrams.
Done it a dozen times to play with and show kids. You would have to learn what a bridge rectifier is :

OR:

Like RadioShack part number 276-1152

Connect the audio amplifier output to the pins marked ~ or 'AC'

Connect the lamp + to the pin marked +
Connect the lamp - to the pin marked -

Play music and connect a DC voltmeter to the + and - terminals; keep volume under 12Volts reading.

This is sort of an schematic; the zigzag line will be your lamp. The ~ symbol to be your amplifier output.

The problem is that CCFL-s operate at a very high voltage, not 12V.

The inverter may not be happy to run from the output of an amplifier. And, I suspect, he also wants to drive speakers.

 

[Externet]

Perhaps am wrong, but I assumed these type:

They work fine even in parallel to a subwoofer.

Came across another site :

Or can be used with a dedicated small audio power amplifier, around 10 watts
