Rocksford Fosgate Amp

[Elvis R]

I have a RF 5002 car amp. I changed one of the output mosfets, now it powers up and plays, but the audio cuts out and comes back on at a frequency of 3x 5secs. The power stays on - visible by the LEDs, but you can hear the blips.

I suspect the regulator circuit. Any idea where I can get parts for this?

I hate to be the bearer of bad news, but rockford fosgate has a tendency to use parts available only from them and do not sell them. Your only other recourses are to send it to rockford fosgate, or experiment with parts that may have close parameters to the ones you need to replace.

You are absolutely right. The regulators are all on one board, that requires you change all four, when one goes bad. I had that problem with the mosfets: I had to make my own heat sink to replace to one bad one.
I will work on the amp this weekend. Update pending...
