First up is a Rockford Fosgate T10001bd..

Story: was left in a cellar for over a year, a little damp down there.. was hooked up to 1 alpine type r 12 @ 2ohm for about 10 minutes, was hitting hard.. then started smoking and wouldn't turn back on.. Pics show one corner something got blown out, black $hit and such...

I plan on changing the FET's and Output Transistors.. what are these other transistors?

The left 3 question marks (marked with 337 and 317) are voltage regulators. The right 2 question marks are the rectifiers for the power supply (U1620, etc). None are transistors //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Thank you sir!!!! Do i have my FET's and Output Transistors mapped out correctly!?

 
Man if you don't know what your doing, most likely you are going to fry those amps even more. The amp with the cooked power supply your probably going to need to replace the gate resistors and diodes, when the power supply goes it usually takes out the gates, and sometimes the power supply transformer could also be shorted out, you also need to check the power supply IC also.

Sorry. I'm upset that they placed new specs in. You know, the degree.
