hi apex sir,
can u tell me what is the output ac volt for 3200w?

 

[AndrewT]

You can work it out from
P = IV = I²R = V²/R
V = sqrt(P*R)

 

[jaagut]

let's calculate using formulas given by AndrewT,

P = 3200W rms

let's say we will use 8 ohms speaker,

V = sqrt(3200*8) = 160V rms

for 4 ohms speaker,

V = sqrt(3200*4) = 113V rms
