That metal bar I think you are talking about is the rails or the windows, you cant move or cut it unless you want to leave your windows up.

If you ABSOLUTELY must get those speakers in, go to http://store.autotoys.com in the dash kit department, SPEAKER ADAPTERS and get a 1/2 inch space. This will space it out for you slightly. Your door panels may not sit as flush but at leasy your magnet of your speakers will fit.
