[QUOTE="creyc, post: 2260146, member: 570559"] I believe there's another way to prevent clipping, too. Its a feature on some McIntosh hifi amps known as an autoformer, and it's on the outputs. It's a pretty interesting idea. It lets the amp output a specific amount of power, regardless of lowering resistance. The idea is to produce a smoother response when the speaker its driving nears its impedance spike; power output stays stable rather than jumping up to meet the lower resistance. Now, wether or not any car audio amps have autoformers on the outputs, or how well it actually works in practice I have yet to see. But theoretically....

A friend of mine has this job and he knows a fair bit more than than your average consumer. But even still, bring up Ω and he gets confused. (despite my repeated explanations :\ ) It's merely connivence taking over. Go to Best Buy to get a new CD, computer, big screen TV, subwoofer, digicam all in one trip rather than going to a specific shop that specializes in each of those categories. You'll get better equipment (and probably pay more) going to an audio shop, or a digital camera store, but because its what they do you'll have a much more informed decision and get what you really want, sacrificing connivence and probably a few $$. The most extreme example i can think of is Walmart, who's goal seems to be able to sell you anything (and everything) in the world, so long as its junk. :\ Long live the little guys! [/QUOTE]
