Ok I run my firebass at 12:00 gain and 12:00 Volume for 2-3 hours twice a week, @ 2 ohms. The red protection light lights up only on hard hitting notes. and only for a short period. Ive ran it this way for about a year now with no problems. Last practice it cutt out during some really hard slapp'n. Is this common on firebass's ran this hard? I am considering biamping just to take the load off the firebass and run it at 4 ohms... insted of 2 ohms. any input by anyone with a simular experiance.
