If you have any problems with it let me know I have fixed 100 fosgates, the biggest thing you might have problems with it soldering the fets to the heat sink board.

here is my email joesch_1999@yahoo.com

thank you very much for your help! I tell them I'm not an electrician. but with the help and guidance of you, I will encourage me to fix it.! there went up as an image diagram which are the components, the number "r 20" is? mosfet is next!

cambiare all IRF9540 and lm337sp, and two others, ie the two sides.

it uses irf z40 in the n channel, check those, check the regulators lm317 on one side and the lm337 on the other, but there has to be a bad p channel fet as well n channel 95 percent of the time blows because something is wrong in the p channel it uses a h bridge in the p channel which means p and n channel fets 9540 is the p channel fet 540 is the n channel fets check those and when you get the bad ones replaced make sure you check the zeneers off the power supply and the caps before powering it up rockford amps are not forgiving if you don't make sure everything is good it will blow them again and it takes time to solder fets to the heat sinks, don't let your hard work go to waste by powering it up before everything is right

if you don't understand what I mean by p channel and n channel, N Channel is the front of the amp where the power converter is it's the thing that looks like a spider with leads running to the fets green and red leads, p channel is the back of the amp where the big capacitors are and backwards basically the power chip is behind those caps that also needs to be checked, but most likely is good.
