Default 20,000+ Watt Chinese Amplifier

I've been considering this Sinbosen FP20000Q amplifier to power my 2 JBL subs (4-18" speakers total). The power output in this "capped" out amp is massive, and I believe it sells for less than 2 grand.
It's 4 channels, but you can bridge pairs for up to 15,000 watts to a single output! I think the 8 ohm max bridged is still 9,300 watts.

A person doesn't need that much power for a home theater, and you'll be wasting a lot of money because, you're not going to use that much wattage.

You do if you want to reproduce sub-bass in the teens and lower.
Just because you can't fathom a need or want for it doesn't mean that's the way it is across the board for everybody, but thanks for your input.

20,000 watts, are you kidding me, they used to have a talk about IMAX before showings at our local IMAX 20,000 watts was what they have powering all the speakers in IMAX.

The JBL drivers I'm using can handle ~16,000 watt peaks, apiece. I'd be running the 4 channels bridged to 2 outputs, and these are only for sub-bass below 30 Hz where the power is needed. I've modified the subs (2 JBL 5628), which are rated to 18 Hz stock, but I've measured 14 hz (-6dB) with them coupled in a baffle wall below the screen channels with ~1,500+ watts apiece (2 Crown 2502s bridged). The extra power may help get them lower. Each would only be driven with ~9,300 watts.

I've been researching this amp and have read of one too many failures after a couple years use at high output.

I'm not surprise because the overall, highly elevated technical specifications of that piece of junk just seems too preposterous for it to be made of good, state of the art quality. When certain specifications are too good to be true, then 99.9 % it is.. It's probably a knockoff! You don't buy cubic zirconia, and expect the authencity and value of a real diamond.

Initially this amp looks pretty good internally. The high power caps are of very good quality, but it must be something within the design topology.
