hello all, completely new to the sound industry i am slightly confused with what sub i will need to support 2 4ohm 230watt speakers (rms 75 watt each) and a 4 ohm 600watt sub (rms 300 watt) will a 4 channel 1000w sony N1004 be safe to use and still maximise the most out of the speakers and sub? thanks in advance. cooper
