It's difficult to see in the photos. Are you referring to the transistors on the upper right corner of the board?
whoa hold on a minute boss go slow ,i know where you going but let me take the part out and clean it so you could advice me how to go foward

Set your meter to ohms and touch the probes to the burned area. Place them as close as possible without them touching. Does the meter ever change from OL (or whatever it reads when the meter leads are not connected to anything)?
ok like you see in the picture not all is burned and by the way sorry to sound like very desperate i get really nervous when it comes to fixing car audio,
anyways you want me to turn my multimeter to ohms and test the burned part ?
If no part of the blackened area caused the meter to change from whatever it reads with the probes not touching anything (no matter how close together the probes were), you don't have to cut the burned area away.
To replace the SMD parts, you'll have to use discrete parts as shown in the photos I posted. You'll need two 1N4148 diodes, two 220 ohm resistors and two MPSA56 transistors. You'll have to scrape the traces and wire the discrete parts as shown. The collector legs (leg 3) of the MPSA56 transistors are soldered to the ground plane on the other side of the board.
