CRESCENDO AUDIO BASSCLEF-4K

I’ve always been big into systems. I’ve been using the same amps for the last 15 to 20 years. I decided to upgrade before my Amps turn to dust. I first purchased an Orion xtr2500.1dz and was impressed at first. Bought through amazon. Until I had issues only 3 months into usage. Orion’s customer service leaves something to be desired. Anyways. I then bought an Orion hcca 1500.4 for my highs and that amp is pretty impressive except for the internal fan sounds like it’s going to explode. So I decided to try the crescendo BC 4K from Down4Soundshop. The staff was extremely friendly and helpful. I also purchased a sundown audio 12” V2 D4 from them. The speaker is really nice but the amp is the nicest amp I’ve owned probably in my lifetime. It’s only been installed about 3 days now and I have 3 12” subs running at 2.67 ohms. Gain barely up and that amp puts out really good sounding power. It’s stayed ice cold at that impedance and still puts out power. I am extremely happy with the amp so far. I just need one more sub to make 6 12” and I’ll be able to drop my impedance and really see what the amp can do. I’m sure it will seriously impress me as it has so far. Very happy. Will purchase another soon to strap Or maybe the 6k. Very very pleased. Such a different clean powerful sound compared to the Orion. Thanks guys at Down4Sound.

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

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.

The crescendo Bc4k is a very nice amp it looks as good as it performs. I have already bought a second one to match my first. This amp has change my brand forever.

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.
