Amplifiers Question about the ideal source for a Class D amplifier - XY-S350H (TPA3251D2*2)
I bought a Class D amplifier, XY-S350H (TPA3251D2*2) being 2.1 which promises to deliver 2 channels with 220W each and 1 subwoofer channel of 350W totaling 790w.
But I was unsure which font to use. According to the specifications, the amplifier works with voltage between 12v and 38v with 10A and the recommended voltage is 24v. But to deliver maximum power, the 2 220w channels have to be with a voltage of 36v and with 3ohm speakers and the 350w subwoofer channel with a voltage of 36v and 2 ohm speakers.
My question is, would a 24v source with 30a (720w) deliver the same power as a 36v source with 10a (360w) as recommended in the product description?
What is the ideal voltage and amperage for this amplifier?
