Couldn't you please show how to do a class D 4 channel amp?<br /> <br /> <br /> I have a 320watt (peak) 40 watt/channel RMS 4 channel amp..... I'm told it eats a whole lot more than just 320 watts from my car's electrical system though, because its inefficient class AB as you said.<br /> <br /> well my stupid little 40watt per channel, 4 channel amp killed my alternator (it was only a year old too), I'd love to know how to get the same output to the speakers without the huge draw on the alternator ---- and also it should save fuel too (a huge amount i doubt it but a little maybe)<br /> <br /> thanks for the great website<br /> <br /> did you ever get an x1800 to play with?
