I have a Kicker 04kx250.2 amp and pushed it ta limits......It burnd 2 IR.s been replaced but i saw a problem. after i fixed the IR.s the part i need is melted so i can not read the part number to order it. some one could help me so much if they have the same model and could tell me the number. look at the part marked with the pencile On the board the Q1 is the spot on the board.

If no one else offers any suggestions, remove the transistor. Set your multimeter to ohms. If the solder pad for the left-most leg of the transistor goes to the B+ terminal of the amp (possibly via a low value resistor) and the center leg goes to pins 8, 11 and/or 12 of the tl494/tl594, the transistor is likely a 2sb631 or a 2sb649. The transistor is used to switch power to the tlx94.
If there were more than 2 of the IRFZ44 transistors (the ones most commonly used by kicker) in the supply, you need to change all of them. It's very rare that any survive. When one goes, they all go.
Did you check the audio transistors to see if any had failed?
