[QUOTE="squeak9798, post: 3685166, member: 555320"] I can't get the page to load, but it's [I]definitely[/I] not a pure class A amplifier. I don't believe it's even "high biased" at all either. Just a run of the mill class A/B. One thing to keep in mind is that in class A operation, the outputs are always on. So they will draw full current even at idle with no input signal (which is why it's easy to tell how much "class A" power an amplifier will have by looking at the idle current). Class A operation also has a maximum efficiency of 25%. So under perfect conditions (14.4V & 25% efficiency) a 790w class A amplifier would draw a [I]constant[/I] 220A. Good luck with that electrical system [IMG]//content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif[/IMG] [/QUOTE]
