[QUOTE="hispls, post: 8833659, member: 614752"] This whole high impedance thing comes down mostly to damping factor which is the ratio of output impedance of the amp vs. load impedance. There's unavoidable resistances everywhere and the lower your final load is the worse your ratio starts to look. Whether it will be audible at 2 ohm is questionable but you certainly eliminate that as a potential issue. If you're only needing 500W out of that amp it's definitely better all around. Efficiency gains, SQ (may or may not be audible), and not having to worry about breaking the sub are all good incentive to just run 8 ohm in this application. If you feel you need more output that amp shouldn't struggle at 2 ohm but you will need to be conservative with the volume knob if you don't want to smoke that sub. [/QUOTE]
