So you just put in new mosfets and expected it to work?

Mosfets have driver circuits and the PWM control IC that drive those circuits all has to be working or you will have no luck just replacing mosfets. That's not how you repair amplifiers. More to it than just replacing mosfets. Who recommended to just replace the mosfets? Rockford?? Surely not.

actually I went in and did some trouble shooting and it was only the fets on the power supply side its been working since the day I posted this but thanks for your input , not needed tho I asked for help not someone to ***** like an *******

 
You have a multimeter? See If amp is getting power,remote,and ground. Something so simple is usually over looked. Loose ground can cause an amp to not come on. A grounding out remote line can cause it to. Make sure no cuts in wires. Good ground. Fuses on amp itself.

Whatever, you got lucky that it worked, 99% of the time bad drivers and more, not just bad mosfets. People act like I don't know wtf I am talking about or something.... Misinformed to say the least. Sorry if I gave the wrong impression, I just see people try to do exactly what you did all the time, and it always = fail.
