So, it's sometimes said that the bridged amplifier "sees" a 4 ohm load(with 8ohm speakers)or a 2 ohm load(with 4ohm speakers), which isn't really correct since the speaker stays the same, although the extra current load on the amplifier is as if the speaker impedance was lowered.
That sounds like a little double talk to me.You say the speaker impedance stays the same but the extra current load on the amplifier is as if the speaker impedance was lowered.Then when using an amp in bridged mode the amp does act as if the impedance of the speaker has been lowered.When I talked to Parasound about doing this very same thing they told me that it would be like the cutting speakers load in half.
