Thanks for posting.
The amps themselves are reasonable designs, look like grounded output QSC designs, but the specs are fully made up.
An amp which puts out 300W per channel into 4 ohms, will put out almost twice that bridged into 8 ohms, or 600W RMS.

How can they spec 1400W RMS into 8 is not even cheating, but bad/impossible Math  :duh

And original spec is not plain RMS but EIAJ, a very permissive rul which accepts as good power put out for a microscond on a good day and with wind blowing your way.
Oh well.
