i got this amp      http://home.indy.net/~gregdunn/dynaco/components/ST400/index.html   from my uncle. he was gonna throw it away and i said no way i want it!!!! it seems to be a good amp. it's priced at $725! i was wondering if i could use it to power a wo32? it's 200x2 at 8 ohms and 300x2 at 4 ohms. is that sufficient enough for 2 decware subs each getting 200 watts? or i might get these http://www.partsexpress.com/pe/pshowdetl.cfm?&Partnumber=295-550. well please tell me what u think.
