Home Sub Enclosure

Systems

Can I use the GNX124's to make a home sub? I have an old extra amp that I can use to power the sub and my current recieiver has a subwoofer out.

I want to make an enclosure like the Polk PSW-650 that has dual subs and is nice and compact.

I am using GNX124's because I can get them at a good price on my limited budget.

Thanks!
