External amp to power a broken sub?

Hi.

I have a KRK 10S 150w Sub speaker. When I power it the main fuse blows, I've gone through a few fuses fault finding but with no joy in finding a fault, Therese nothing obvious when I look inside the unit, blown caps etc. New whole parts (ie pwr supp) are thin on the ground as its pretty old, to replace the whole thing would be about £400 2nd hand.

In short I want to get a stand alone amp (150w), drill a whole in the sub cab and connect directly to the speaker from the amp bypassing all the electronics of the unit and just utilising the cab and speaker, feeding the amp from the SUB op of my DtoA converter which in turn is fed from the Dolby Atmos software (sub op).


Can anyone recommend a "cost effective" preferably class D, balanced input amp that could do this. The speaker is 8ohm, 10 inch. Or tell me why this is a bad idea!?

Thanks!
