Component set impedance reading higher at amp?

For one you're measuring the DC resistance. First of the speakers and X-over and then with the addition of the speaker wires. Not to mention the resistance of your DMM's leads. They're all part of the equation. A DMM cannot measure impedance. Impedance changes with frequency. Resistance does not.

please correct me if I'm wrong, but shouldn't the average passive component set read around 6 ohms ??? which should be perfect for an amplifier ...

You can't measure the impedance of a X-over with a DMM either. DC resistance and AC impedance are NOT the same things.

Hey man, why are you trying to make things complicated ???

I know the difference between AC and DC. I've been an electronics technician for over 20 years.

We're talking car audio where the amplifier has to see a certain DC ohm load to operate correctly.

It's you that is makiing things complicated by making statements about a topic you obviously don't fully understand. Impedance changes with frequency. Resistance does not. A speaker may be rated at 4 ohms but the load it presents to the amp doesn't remain at 4 ohms at all frequencies. A typical 4 ohm speaker can have an impedance as high as 100 or more ohms at resonance. That same speaker can also dip below 4 ohms at some frequencies. This is why you cannot measure impedance with a DMM. Amps do NOT need to see a DC resistance to operate correctly because they drive a speaker which has impedance, reactance and inductance to consider. A simple DMM cannot take all these factors into account when taking a reading.

Read my post. Did I say ANYTHING about resistance ???
