Mosfets keep blowing while amp is in protection
I got a kicker zx650.4
I got the amp with blown fets(power supply).
I ordered all new ones and put them into the board.
When testing the amp as soon as i give it power it goes into protection.
However the first time i left it in protection it blew fets. So i removed them all, tested them individualy and there were 3 faulty ones. So i put 10 working ones in again and turned the amp on. This time it cooked a few of them without the amp even going into protection.
I checked diods, and resistors on the power supply side and they seem to be fine.
Anyone have any ideas? maybe something i'm missing?
Thank you

luke paddel :P Sup bro?
its Roman....
Ya i know of them...
I actually just found a VERY good read about the same amp.... and what they said is that output fets were messed and they were killing the PS fets... sooo gonna have to solder them out and check them all individually.
