Thank for all the replyes...
so..
I get the 12v to the BUMP (NOBUMPHARDWARE) with the YELLOW wire (and this its the only things i have get it)
After i give to the BLACK of the BUMP the GND (i bring the 12v and the gnd direct from ATX POWER SUPPLY)
(my amp dint have any switch to turn ON and OFF)
After i connected Orange/White to + ofe the ampli and the GND to the - of the amply....NOTHINGS HAPPENS no 12v
I had cheched all the output (included orange) and no wires provide 12v
I feel soo stupid...
but this is the simple wire connection.....
