I'm trying to hook up the 6x100W TDA7498 Class-D Amplifier 6x100W TDA7498 Class-D Amplifier Board 320-307 and make it a 5.1 surround system. Or at least output all six channels using only channel 1 and 2 as input channels (using red and white RCA cables). If anyone could show a site with instructions or explain it themselves it would be great.
