just traded my Ampeg PR410HLF for an Eden D410XLT. Before I left to go pick it up he told me it was 4 ohm which is what I wanted. When I got there the back of the D410XLT said 8 ohm. He told me that it is a 4 or 8 ohm depending how you hook it up. What he said was that if I only use 1 speaker cable it is 8 ohm but if I run 2 speaker cables out of my amp to both speaker inputs then it is 4 ohm. He said to think of it like hooking up 2 8 ohm 210's. Does this sound right?
