Problem with a 30-0-30VDC @10amps transformer/SMPS and 400WATT RMS mono amp(not PMPO) Answered

First of all thank you so very much, i have successfully build my rectifier but now i am having a problem with it. Can a 30-0-30VDC @10amps transformer/SMPS, power a 400watt-RMS car sub @4ohms with a 400watt-rms mono amp. When i tested the 400watt subs, the gain is too low or am i doing something wrong here.

This is my 400watt-rms amp...

A non-power amplifier, yes, one that could adjust tone too, but really a voltage amplifier.

OK the "voltage amplifier" it was just out here(:

https://www.instructables.com/id/Voltage-Amplifier...

but i am little confused here, so i need to connect the
"voltage amplifier" to my 400watt rms mono amp to get the full output
power, to drive my Pioneer 400watt rms sub-woofer, yes. Thank you.

Exactly ! The PRE-amp changes LEVELS, the POWER amp changes power.

45-0-45VAC-DC power supply and i don't get enough time to make one
myself): but when i get one and assembled my amp, i surely will post out

Yes, you can get 600VA from the transformer, if your amp is reasonably efficient, then you should be good to go.
