Why is SQ better at 4 or 8 ohms compared to 1 or less?

[QUOTE="rsgladwin85, post: 6992690, member: 607720"] That statement is and isn't correct. The lower impedance does force the amp to run hotter, but that in itself isnt what causes a loss of "sound quality". As electronic components run hotter and hotter, they become less efficient, therefore not providing as solid of a signal. Example: An amp running at 300w RMS at 4ohms runs at 86% efficiency, meaning it will supply the same signal quality and strength 86% of the time. Bumped down to a 2ohm @ 1200w RMS load you might get say a 70% efficiency rate. Same general principle for any power source. The more load on it, the hotter it gets, therefore the less efficient its signal. [/QUOTE]
