You can connect it to the PC's power supply.

PC audio --->FM modulator~~~~~~Car radio ---->speakers.

Allow me to rephrase.

You have power to the PC right? (yes)

Your sound signal goes from the PC sound card to the FM modulator right? (yes)

if the PC is on the PC power supply outputs 12v power, use one of those 12v lines to power the FM modulator.

That means if the PC is on the modulator has power.

but the thing is i cant hook up modulator because I dont have my stock radio anymore i replaced it with an indash LCD from www.digitalww.com

If you don't have a radio then a FM modulator is completely useless. You need to buy an amplifier.

PC_Soundcard ---> Amplifier ---> Speakers

OK, then why were you asking how to hookit up if you are not going to have a headunit in the car?

if you still need (in your mind) to use an FM modulator.... maybecause you have one, The first step will be to instal a headunit

have fun

I have no clue here, so let me just sum this up cause its kinda funny.

you want to know why your FM modulator(which sends out a FM signal for a radio to pick up and play) isnt working with your (non existant) stereo?

if you remove your stereo what would be playing the music?

you have plenty of options
-power supply of pc. since it does do 12+
-car cigarrette lighter another 12+
-or any place on the car such as HU wire, fuses, steering column bolts, ..i can keep going.

the only problem with pc power supply is the fm modulator is only on when the pc is on. But I suppose if you are using the modulator to get sound for your pc, then this is fine.

other options, the problem is if you accidentally leave it on when you turn your ignition off, then you can sap the battery. Ofcouse oyu can use a ignition live only source. But the problem with this is now you can only get sound when the ignition is ON. =)..

I would saw connect to thte pc.
