The all new Sundown Audio SCV amplifier series carry on the legacy of our acclaimed SAZ series amplifiers. The SAZ line was our flagship amplifier line from 2006 through 2014 but they have now been fully replaced by the new SCV line.

We built off of the legendary SAZ platform and the 8-years of experienced we had with them. The biggest difference is that we have fully optimized the power supply for 12v electrical systems (maximum operating voltage of 15.5 volts). This allowed us to offer more power per dollar as well as a smaller footprint per wattage level to our customers. 

  • RMS at 1 ohm : 4000-watts
  • RMS at 2 ohms : 2000-watts
  • RMS at 4 ohms : 1000-watts
  • LPF : 35-300 Hz
  • Subsonic : 10-60 Hz
  • Dimensions: 8.25” x 2.32” x 24.4”

    Sundown SVC 4000D

    Posted by Unknown on Sep 17th 2018

    The guys at Down 4 Sound hooked me up and I was able to grab this amp from Sundown. installed it on two Sundown U 15” subs on two limitless lithium 45ah. This amp pushes the subs great. Can’t wait to get another one to strap them and blow the windowsheild out.

    Awesome 4K

    Posted by N.E on Jul 28th 2018

    I haven't clamped it, but with good electrical and enclosures, no doubt this thing is putting down the power! Doesn't really get warm 'less you push it hard. Under normal operations (1ohm) She stays nice and cool. Really slams a single ZV5 12 and rattles some balls. Buy it.

    Moved on with a Crescendo 5.5K for my Fi, but will be keeping this 4K for another mini build. Highly recommend.

    nuts for days

    Posted by mike on Jan 20th 2017

    If you're looking for an amp with a lot of nuts this one is great. Plenty of power at .5 ohms to make anybody happy. I dont even care about a warranty. I love this amp

    The sundown audio SCV-4000D is a power house when it comes to bump in the trunk! A definite buy in my book!
