This amp punches way above its weight.

I want to say this AMP is well worth the investment. I am running it on 1 10" DVC 4 ohm Sundown Audio E series and man will this thing rock. I can't wait to add my other 10" and get the full potential out of this amp. As for the service what can I say they are outstanding had some problems on the set up of the AMP and they talked and helped me through everything. They are a great group of people and glad I ordered through this company.

I love these little amps. Other companies have been making similar amps but I will only buy sundown . Great power in a small package.

I can't really review this product since I have been waiting 21 days and still have not received my amp. Not sure when or even if i will get this product. I had to file a claim and nothing is being done about this since it hasn't been 30 days. Once I get this or if I get this I will write about this until then watch out for the shipping, you don't know if you will get the product or not.

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.
