power question, i need power for my cooling fans Options

[whitefuzz]

FINALLY i have a holiday! (3 weeks)
so now i have the time to take care of the setup of my trunk i've been planning for a while now

still have a question:

my amps come under plexiglass
that will look sweet but that way they're also in a little box witch will get filled with hot air once the music starts
that air should get out so i got some nice pc casemod cooling fans

now i m wiring these

they should start spinning when the radio starts to play but i can't put em on my remote cable
so i m now looking for a cable in the car that has power when i start the car
en goes back to nothing when i shut down the car...
that way the fans will start spinning when i start the car & stop when i shut it down...
that should give the amps a nicely cooled "box"

now my question : where can i find that wire?
doesnt really matter to me wich one
but it should have power when the car starts en return to nothing on shut down...

i thought about the cig lighter cable (cuz i'm removing the cig lighter and replacing it with my remote bass control button) would this be a good idea?

mmm my head unit is a sony cdx m700r
those sweet blackpanel thingys

my antenna goes up with the radio but not with a cd...
so that ain't an option...

i just hooked everything up on the cig lighter power...
at once i removed the cig lighter and put my remote bass control in that spot
looks really nice

tomorrow i'll start making the second mdf floor for my trunk
this is the one i'll attach the coolers too
so in a few days (maybe a week) they should be working
