you must have some diagram b) must test some around components like capacitor+diode+resistor+ic+Trafo , that will be in short circuit this will provoke the short in your MOSFET transistor.
First of all is the mosfet your talking about in the output section or in the power supply section? Most car amps use mosfets in the power supply section, some use them in the output section. To test the transistors in your amp, take a digital volt meter and set it to diode check. Then take the leads and put them accross the first and third legs of the transistors. Usally the red test lead on the first leg and black test lead on the third leg of transistor. If you get a reading of 000 then transistor is shorted. If you get a reading below 600 then transistor is on it's way out if not allready or it's next to a shorted transistor that is it's complimentry output transistor. comonly you will have 2 transistors working together, one NPN and one PNP per a channel, or 4 of them in a bridged type output circuit depending on the watts and how man channels your amp has. I was just looking at the specs of this amp and it's got me confused. It says it's a 2 channel but looking at all the info on different pages it says at 4ohm:200wattsx4 and at 2ohms:300wattsx4 and 1 channel mono 600watts into 4ohms. weird for a 2 channel. anyway that is how you test your transistors. Same way for the power supply section but, you will come accross a couple or more switching diodes that look like transistors and you will get a 000 reading when you test those like I specified. They rarely go out and most of the time there is only 2 of them. They will have a diagram like a diode on the front showing you which way the power flows. Let me know what you find out. Your amp should have went to protect mode if you smoked a mosfet.
