Currently with SA-10 D, im using Old series Pioneer 304 IMPP 300 Watts RMS MAX.
It's giving tight sound at medium power, but blows-off da hook on high, gets me fearsome of blasting this baby diaper 304.
This is actually my 10 years old woofer, & it's still runnin' & kickin' !
Just got the surround cone foam replaced with heavy duty rubber, taken out from memphis 12".
