SOURCE: my amp earthquake ph d2 output mosfet number...rfp 40n10

Hello luistecnico2,

Those cross-reference OK. Go to www.mouser.com and do a search on both numbers. You'll find that one of them was manufactured by STMicroelectronics and is currently obsolete. The other is manufactured by Fairchild Semiconductor and is available at a cheaper price than the original.

Hope this helps.

I would go with a 40 or 60 amp fuse, this should be ok, you will hardly every run the amp to full capacity so its better to be safe than sorry.
