Its not necasarily the mosfets.
It could be shoot through if you don't have any dead time.
Or your switching frequency might be too high.
It is around 325khz....i want to drive this amp as bridge at 4ohms load..what out can it deliver at 4ohms bridged at 40-0-40 dc voltage??
n- type mosfets - no problem , but the lack of p-type is great. You need to parallel 9540 in amount you need.
how? directly or a buffer should be added
There is a buffer already. So I think you can use up to 3-5 parallel mosfets.
Are you sure about that??
I just need two pairs,will it work fine with it?
I am unable to set frequency..i want to use it at 250khz

I did find any schema for jbl1100...can u plz attach it?
I can , but only at weekend , I' m on a vacation now.I did find any schema for jbl1100...can u plz attach it?

Yeah sure with ur ease..
N happy vacations
I would avoid P-Chan MOS-FETs because switching characteristics probably don't match the N-Chan one, so use all N-Chan and this is a really fast one Infineon IPP600N25N3.

I have used Infineon COOL-MOS parts for power supply's and they run really cool. I didn't check on this thread to see what schematic you are using.
