    • Giddy up
Like a reaper. Tiny pepper but packs a punch. This with a ct 12 at one ohm and she gives me what I want. So small can put so many places. Definitely recommend

    • It lasts

    • Powerhouse
I love this little powerhouse, it kicks without breaking a sweat. Highly underrated by the manufacturer so don’t blow your subs. I’m using this amp with one Skar Audio 600 rms sub @1ohm and it’s turned down and it’s beating the hell out of the sub and has not gotten hot yet.

    • Tiny Amp Great Power
It puts out awesome power, bass knob with the clip and power lights, and sounds great. Thanks Sundown Audio

    • Works as expected.
Bought this amp cause my last one blew, this amp comes with a clip light on the bass knob so you won’t blow your amp. (Just get the 1000 watt version of the amp.)

    • Sundown "long term" quality is questionable.
This amp failed w/in the first year, but since they no longer sold it, I had to pay to for an upgrade if I wanted to do anything w/it. 6-8 months later, the upgraded replacement failed too. Reached out to Sundown, they offered 30% off a replacement...
