KVA = Kilo Volts Amp = 1000 Volts Amp

Now Watts = Volts * Amp * Power Factor, this power factor (PF) varies from product to product, i.e. if it is a normal bulb the power factor will be 1, so for 300 watt bulb at 230 V the current will be 300/230 = 1.3 Amps, but if it is some other type of light like tube light than the PF comes in picture. Generally a good company tube light will be have a PF 0.5 - 0.6, hence here if the watts is same i.e. 300 than the Amps will come to 300/230/0.6 = 2.17 Amps. A Transformer in Electronic equipments will have PF not better than 0.2. don't know about SMPS.
Again the Sub Woofer of 300 Watts will consume that watts at peak performance, the average consumption will much less.

so brother

can you please tell me that i have a 6amps stabilizer so how many watts it can handle and can you please tell me how many watts does it have
and can 6 amp stabilizer handle my 500 watts consumption av receiver + 300 watts power consumption projector

and one last thing

if i purchase another stabilizer like 3amps power

so will it carry my two subs with 300 watts each power

In theory, a 6amp stabilizer should handle 1320 watts (6*220) and a 3amp one should handle 660 watts. However, it is suggested to go for a higher rated stabilizer than what you need (as per theory). Go for a 10amp one instead of 6amp and 5amp one instead of a 3amp.

S Kumar is correct, you should go in for a higher powered one.

but brother

v-gaurd don't make any stabilizers higher than 6amps :sad:

can't i use 6 amps stabilizer for my 1200 watts need because if we multiply 6 x220 then we get 1320 watts

and another 6 amps for my two subwoofer whom are 600 watts total power
