I was given a Rockford Power 1000... and i was on the brink of scrapping the amp in this thread because it had already costed me a set of outputs, so I ended up scavaging parts to fix the 1000. I know... bad Eric. Very bad.
In this amp's case, I actually figured out how to fix it and would actually like to fix it now... and therefore I need to replace these parts for new ones, as well as a bunch of other parts which I've already got tallied in Digikey.
I know the resistor is a 2R7 but I'm not sure about it's wattage. Also I have no idea what the cap is supposed to be. C227 and R277.
Hopefully I can put in the order and get this and future Rockford's fixed up!

I figured the 2.7ohm resistor is .5w because of the size so I put it in my cart.
Still not sure about the capacitor... Using Digikey I put the size in as 3.18mm x 2.49mm which is the closest I can measure to what is available on Digi, and it seems Digi came up with a 1uF 16v cap or a .33uF 100v cap. Is that right?

I have a question? Not to "thread jack" or nothing but I thought it would go along to this. Anyway my question was that can the power supply mosfets blow out if the amp is making double the output rail voltage or not double but just maybe 15 or 20 volts higher because I was just curious to see what my punch 40.2 would do at 2 ohm bridged and it did 35 volts max on a 12 volt supply.
With no load, the higher rail voltage wouldn't stress the power supply FETs but if you increase the rail voltage and drive it into the lowest rated impedance, that would stress them more than normal and could cause them to fail. Running it with a load impedance that's lower than the lowest rated load impedance can cause it to fail with normal rail voltage. It would be much more likely to fail if you increased the rail voltage.
Oh I see now that's how most amps fail anyway. But if i wanted to increase to make it handle alittle more could i always just change the power supply fets to higher voltage and current handling? the OG's are MTP50N06V and are rated 42A and 60V. Not that I'd like to use this specificly for bass but I was just curious because some people told me it can power four subs at once or more.
The voltage rating isn't important for power supply FETs. 50v FETs are sufficient. Generally, higher voltage FETs are rated for less current. Replacing the original power supply FETs with ones rated for higher current probably won't improve reliability much because the output transistors are likely to fail if you drive a load lower than the lowest rated impedance. If you want to use FETs rated for more current, the IRF3205s work well in most of the Rockford amps.
You can connect any number of speakers to any amp as long as they're wired correctly.
