[QUOTE="Graves, post: 8720861, member: 681362"] I like to do 0db personally but -10db would be fine as long as you are not maxing out you system with music that was recorded higher than -10db... -5db would be a safer bet especially if you are planning on EQ boosting. I don't know the gauge of the wire but speakers wire carries AC and like you said each circuit is only seeing ~230 watts, sounds like you have plenty to me. As for the math just multiply your impedance by the desired RMS wattage (for the channel) then the square root of that will be your target. i.e. 460 x 4 ohm = 1840 sq rt of 1840 = 42.9 volts or 30 volts if you have a 2 ohm load.
