Hi,
I review that link, it have good information.Theres no way to measure AC Impedance in a wire I know of? Isnt AC Impedance an average anyhow?
My point of the initial post is theres an obvious difference between the AC Impedance of the rated speaker and the use of DC Resistance in the wire. Even at that it doesnt add up.

Well thats my point.
They are comparing apples to oranges...
My other point is saying "yes this is fine" opens to the next issue...
Then why cant I bridge my speakers?

You can impedance rise and many other factors will increase the impedance regardless. however remember Series vs parallel. series = twice the voltage same current Parallel = twice the current same voltage. Like i said it will most likely be ok, its still a dumb tactic but it will be ok. how many times have you seem people run there subs at a lower load than recommended? its no different than speakers, i ran my MM4000.1's at 1ohm and .7ohm mono when lowest recommended is 2ohm. however my impedance rise in the end was 3.1 with a dcr of .7 so im well below dcr but my impedance increased to 3.1 which is y the amp was ok.

But the amplifier and power supply of an amplifier is more stout than whats found in a head unit, correct?
Thus my concern.
And my previous post let me rephrase what I put. Not so much of bridging a channel, but running a set of speakers in parallel to the head unit.

a headunit has an internal amp designed and produced to do whats specified, the same way amps are. if it says 4ohm nominal on the headunit and 4ohm nom on an amp it designed for that purpose. Regardless the amp in either will never see a real 2ohm load. most likely 4-8 and even higher in most cases.
