the crescendo does over rated too in fact i believe they are built in the same plant in Korea. at least the older amps.. if you open the amp you will see they have the same internals, only difference sundown test and rates the amps at 12 volts crescendo does it at 13.8 volts. same amp different name and rated at different voltage
the brutus amps i had them before and after tuning amps with dd1 they didnt do rated so i personally will never buy a hifonics again. i have sundown amps now since i got a deal on them if not i would have had the nendo bc5500d since it does what i need for a very good price
