So I just picked up a Xenon 600.1 monoblock and I am getting a 12 inch type R. Wondering if I should wire the sub for 2 ohm or 4 ohm load with this amp. I know it claims 600 watts at 1-4 ohms but would I get more power at two or four? I am running stock alternator so whatever is easier on the electrical system is a consideration. Anyone have experience with this amp or similar xenon model like the 400.1 or 1200.1?
