Default Bridging an amp... Circuit theory question???

ok eddie, then explain why bridged output @ 4 ohms is equalivlent to stereo
output @ 2 ohms. because each channel only sees half of the load from the
speakers

idiot here trying to make sense of things.

I always thought that a stereo amplifier running in bridged mono mode
inverts the mosfet output wave from one channel and couples that to the
other channel. This is how the circuit creates more power into one
channel.


thats pretty much how it works, one channel pills while the other channel
pushes
actually takes the + voltage from one channel and the - voltage from
the other channel and uses them together to have ahigher voltage.

Another thing. When a stereo amp is bridged mono pushing a 4 ohm load,
Is it true or false that the amps circuit sees this a a 2 ohm load? If
this is true, why?


a 4 ohm load is still a 4 ohm load.
alot of folks say its 1/2 of the load but it IS NOT!
alot of folks say each channel sees half the load IT DOES NOT!
but alot of folks think so.
