This seems like such a simple question, but I can't find the answer. What are the advantages and disadvantages between two different amps that put out the same out of power but at different resistances? Mainly looking for answers on a more technical level, like which will put less strain on my electrical system or which is thermally/mechanically better for the subwoofer. I have a Fi SSD 10, D2 and copper coil, and I'm looking for a 1000w amp to power it.
