Okay first of all, smack some sense back into yourself and chill out.
Secondly what do you mean by "everything is connected thru the center console". More directly are you connecting your laptop through the Ciggarete lighter. Ifso DONT. Wire that sucker directly to the batter with a fuse.
If a GLI (ground loop isolator) doesn't work then it is probably not a bad ground loop. Your power lines are probably filthy. I get mad crazy noise when i run anything through the ciggaret lighter. You need to power all of you componants directly wired to the battery. Make sure that the power cable to you laptop doesn't cross any of the cars wiring and if it does then cross it at a 90 degree angle.
Also you need to isolate what componant is causing the noise. Is it the amp? is it the carputer? is it the lilliput? try different test to see what componant is noisy.
