  • True 1500 RMS, wont go below 1 ohm
Powerful amplifier, best I've found for the price. True 1500 rms. Be prepared though, you need 0 gauge ofc copper wire to power this beast, but my factory battery and alternator handle it fine with no bass cap or anything

  • EST amp I’ve ever owned. Pure power in small package
Hands down best amp I have ever owned. Extremely powerful and pushes my ddx10 to the MAX!!! Clamped 500 watts out of this amp with gain barely turned. Rising to 3.5 ohms. Set gain with a DD1 and I gained 5db. Have yet to clamp it since then. This is a great amp. Highly recommended. I switched from Korean to this and I’m way happier with my setup!!$ ... show more

  • Awesome amp
I had a kicker cxa1200.1 and I loved that amp until it decided to stop working so I replaced it with a sundown sfb1500 and I gotta say this amp blows my old amp away between clarity and and power. This amp does rms power and then some. If your new to this don’t waste your money on cheaper amps just buy this you won’t regret it ... show more

  • Very Happy Customer
I purchased this amp awhile ago. I have it hooked up to 4 MTX 12 inch terminators and let me tell you, this little monster is a game changer. Dyno tests proove that this little amp shoves significantly more power than what it claims. Absolutely pounds the snot out of my subs, highly highly recommend this amp to anyone looking for compact power. 5 Stars from me. ... show more

  • Great amp but shorty after purchase started to clip.
Phenomenal output out if a small package. Great amp but shorty after purchase started to randomly clip. Not good.

  • BUY ITTTT
amazon has a note saying most returned. i don't see why it would be tagged as that. great output, underrated by at least 15%. definitely hitting 1800-2000 with out a doubt!! Bass control and sound quality was a big concern of mine and this would land in my top 5.

  • Does it’s job and lots of power for a small amp
I have this amp set up in my f250. It’s pushing 4 sundown 8s and I haven’t had a problem. Set up is easy with a light to let you know if it’s clipping when messing with the gain. Drove on a 12 hour road trip and it didn’t get hot just warm. And it’s puts out a lot of power for something a little bigger than my lc2i. ... show more
