Hey guyz

i've just purchased a bass tube and an amplifier for it for my car

Bass tube- https://harmanaudio.in/jbl-gt-x1200t-subwoofer-tube.html
Amplifier-http://www.sony.co.in/electronics/car-amplifiers/xm-n502

And i want to hook it to my computer or any stereo output just for fun

and i'm having a spare old computer psu of 17A Dc output through +12V Rail
so i wan't to use that psu to power my amplifier and i dont know how much power it will require

and after searching through the internet i found out that i can do that
