Hi everyone I'm new on the Forum And Comment My Problem:
I Still Have This Orion amp And I Conect to the amp at 8 Ohms My Kickers L7 4 Ohms DVC first day work fine but second day it blown, so i open it and find 4 irfz44n transistor burned, so i replace the four transistor and check the 100 ohms gate reistor and they are fine,so i power un the amplifier with a 10 amp fuse and 12v bulve for proteccion, but when the amp turn on,it put itself on protecion mode and the bulb blink and the green led of power blink to, i check the transistor diodes and are good anybody some ideas can help me?

An externally hosted image should be here but it was not working when we last tested it.

I see that nobody is interested my post, but just as I put an update.
apparently damaged 3 output transistors which caused the burning of the 4 irfn44n
then
4 IRFZ44N replaced, 3 output transistors by replacing
checking resistance of door and look good.
I hope some recommendations or tips if it does not matter anyway

Hey Please, a moderator move this post to the righ place i' think im in the wrong section
maybe car audio section thanks and im sorry!!

no sir, I ordered the parts on Digikey and yes i buy the exact replacement you think i need replace all the 8 of channel or the damaged lot only?
This is a 4 channel amp. It appears that you removed all 4 FETs from the defective channel.
I don't understand what you wrote.
Are the new FETs installed (yes or no)?

Before applying power (after replacing the FETs), set the bias pot for that channel fully counter-clockwise. Also clamp all transistors and insert a 15 amp fuse in the B+ line to provide additional protection.
I put all the new fet's also clamp,I power up the amp but it get hot only on the side i replace the fet's. Some ideas
ok i set it on the way you show me and the dc amps are at 1.88 amp and the transistors not get hot, only a little bit passed 15 min or more.
a question, is correct if Iconnect the amp on series with the b+ of the amp?
