The Belle has a 16-ST1000D Class D subwoofer stage, pretty powerful little amp, equivalent to a SAE/SAZ-1000D. I don't know anything about the Power 1000 25 to Life.... I have the Punch 150 25 to Life.... very nice amp BTW.... need to sell it though I have no use for it really other than to look at it every now and then and think about the good old days and the original Punch 150 and Punch 150HD.
