[QUOTE="Spooney, post: 7208918, member: 584130"] You probably need to replace more than just those burnt mosfets. I would check the gate resistors(the ones connected to the first leg of each fet) and the power supply driver transistors. In an amp this small I would probably just replace all of them just for the hell of it. There are a few reason why those parts from the alpine didn't last. The gate resistors need to be the right value for the fet. If you just had some random fet in there with the wrong gate resistor the fets will fail. Also even if the gate resistors were good enough if the power supply driver transistors were defective they would cause the fets to fail as well. Always a chance that the power supply driver IC is damaged as well. I don't see that happen a lot but it is possible. As far as reading the part number on the fets try wiping a bit of that white heatsink compound across the face of one of them and then wiping it off with your finger. Sounds weird but sometimes it does the trick when the fets are hard to read. [/QUOTE]
