I-Got-Shells wrote well from what i have read the xbox only takes 175 watts but 2.42 amps so yeah...

ohh, mine says 1.74 amps
ill stop and by a new one at best buy

There you go

I know it only uses 175 watts but i would get more than one with 200 watts also.
But thats why it was making that noise it had enough watts but not enough amps, The more the better.
I also would not use it while the car is not running!!!
