What kind of amp?
Specifications are derived by many different ways in order to market the amp.
If car audio, hehe, its all marketing.
Typically, if a professional power amp can go down to 2 ohms/ch min and has a max output
of 1000W/ch, then it can bridge to 4 ohms min and will see somewhere in around 2000W
bridged.
Manufacturers do the following to get their "specs".
1 khz input signal
QSC Audio specs their amps using 20hz-20khz both channels driven at 120VAC.
Typically, if your amp has a minimum impedance handling of 2 ohms, you can only bridge to
4. You're putting both channels into series with one another.
I've been in the professional audio field for 10 years, and I love it

single channel driven
higher voltage on the primaries (check what voltage they test it at).

Into 8 ohms, per the manual:
180 W/channel, stereo
560 W, mono mode (bridged)
Regardless the inflated numbers that all manufacturers publish, why would the
number for the mono mode be so much higher than the stereo spec? Shouldn't it
be double the rating for stereo?
