mosfets IRF640

[teebee101]

I have a Rockford Fosgate Punch 800a2 that I replaced some MOSFETs , and my question is it came with 10 mosfets IRF640 five per side and I replaced all 5 on one side with an IRF640N, should I replace the other five 640's with 640n ?

Many times the N suffix parts can cause strange behavior. Try to replace non-N's with non-N's.
