60amps for this amp??? seems awful small to me.. what model is this?? i would guess it needs a whole lot more than a 60 amp fuse...

nevermind i saw it in your sig... man this amp needs a whole lot bigger fuse than a 60 amp... prob like 200+.. if i took a guess i am not sure of actual power output though

also these dont like low voltage.. the make full power on 17volts. what are you feeding it with??

I used the 60amp fuse just to power it up after repair.

Well local shop wants to much to fix so I'm on my own again.

Well now I've replaced all the IRF 9640's and all the IRFP064N fets and the amp still blows a 60 amp fuse before going into protection.

Any ideas out there?

Anyone with an experience fixing HK4000's, Visoniks want to fix this **** thing already?
