Default MIT Terminator Speaker Cables - Impedance and Resistance

Okay, I have a 2 pairs of MIT Terminator 5 speaker cables and when measured they all show 2 ohms resistance. So if I use these cables will my amplifier actually see to more Ohms of resistance?

Since my speakers have 6 ohms resistance, does this mean if I use the MIT cables the amplifier will see a total of 8 Ohms resistance?

I ask all this because my amplifier specifications call for a minimum of 8 Ohm speakers when using 2 pairs. Well, my speakers are all 6 Ohm - but if the MIT cables give me 2 more Ohms resistance then I should be fine to hook all 4 speakers up becasue the amplifier will think they are actually 8 Ohm speakers. Right?

Thanks for any help on this.

Measure the DCR with the cables attached. If it's 6 ohms or above, you should be OK.

That seems odd,speaker cables should be a nice low resistance,shouldn't they?
I'm assuming the cables are shorter than 100 feet?

Even cheap zip-cord has lower resistance.

Ah, yes. But those MIT Terminators have those large 'mysterious boxes attached to them. A cross-over by another name, perhaps? I wonder what the capacitance and inductance measurements would give us also?

Boxes or no boxes 2 ohms sounds excessive and would dramatically alter the sound of many speakers. I would suspect a wrong measurement or oxidised terminals.

On the bright side, if true, you get inbuilt short-circuit protection
