Quality products at a great price
If you’re in the hunt for a nice Korean built amp crescendo needs to be your go to. They continue to have the nicest looking amps and preform just as well as any other S&I board amps for a better price. Do yourself the favor. Ps. These amps love half ohm. I have a bc6k and 4k both of which absolutely crank at half ohm with no issues

bassclef 4k
Amazing amp, absolutely beautiful. Puts out rated power and more. I have this powering 2 sundown u 12s and they absolutely slam. I have a secondary Northstar SMSAGM220 battery and a mechman 370 alternator. running dual 1/0 inputs for my power and grounds with sky high ofc. this amp never even gets warm and i run it at full tilt for hours at a time. The only minus i would have to say is that the cooling fan is absurdly loud, to the point that its very annoying if i dont have music playing at a decent volume. honestly i think thats the only thing they could improve on.

Cresendo 4k
Wow this amp is awesome. I was running a Skar RP2k then jumped up to the Cresendo 4k . It was like watching tv in analog then jumping up to 4k. There is a big difference . Like night and day.
