This little amp exceeded my expectations in every way! I’m using it to power a single SA-12 in sealed truck enclosure. This thing has tons of power and pushes this sub hard without even breaking a sweat. The amp is barely warm after an hour of heavy use. The clip light is another awesome feature I would never do without now. I cannot say enough good things about this Sundown amp!

Not sure if I have my sub wired at 1 or 4 ohms but she slams. Wants more power than amp can handle, but like I said it might be wired at 4 ohms so that would make sense. All in all, good and reliable for the money and I’m glad it came with a knob that shows when clipping, that saves me cause it’s hard to hear sometimes.

I just hooked up sfb 1k and wow wired at 1 ohm on 2 deaf bonce Machete fights and D4S pro fab box and that amps is pushing them easy i saw amp dyno on sfb 1k and was blown away 1410 rms very happy thanks D4S and jp

I ordered the sfb 1000.1 on the 5th of August and received on Saturday the 7th and im in Pennsylvania great job guys the amp is compact and powerful very happy i recommend for sure thanks d4s and jp i will continue to do business with you guys thanks again

I've had this in for just a month or so. However it is hooked up to a single dual 4 12", so it's only running at 2 ohm. I can run all day long cranked, and it's barely warm to the touch. Haven't had any issues yet. Not shutting down or going into protect mode. It just keeps slamming. I'm satisfied with the amp, and definitely recommend it.

I install plenty of mobile audio and this amp became my go to for entry level systems. My favorite feature is the clip light which helps first timers to save their new subs. I know that this is a cookie cutter Chinese mass produced design but it’s reliable and affordable.

For a small application it delivered like a titan.

Very impress with this amp sits perfectly under the back seat in my tahoe got them pushing 2 8 vd skar at 2 ohm

It's a sundown amp. What more is there to say? D4S is also now my go-to car audio supplier. Thank you D4S!

I have recently purchased this and I must say I love it. It packs a punch for how small it really is and will virtually fit anywhere!
