SFB-1000D - Sundown Audio Monoblock 1410w RMS Amplifier

It's a great amplifier; I power two ORION XTR subs without any problem.

Just got this amp hooked up to two kicker comp r 12s and boy do they sound good! This amp is amazing. The other amp I had made my headlights flash when the speakers hit hard and they didn’t sound all that great. With this amp, my headlights don’t flash (that I’ve noticed) and the subs hit hard and sound good. I still need to fine tune it but with a quick tune it’s a night and day difference. Long story short, buy this amp. Later, I plan to get better quality subwoofers to give me what I’m looking for but for now I’m happy. Nicest quality amp I’ve ever had and it’s small enough to fit under the back seat in my truck. I can’t rave enough about it, I’m so happy right now! Upon further listening I’m pretty sure one of my subs is blown. Udgrading soon #sendit

LOVE IT got it pushing 2 skar d2 10s 40hrz but it does GET HOT, I will remove the bottom plate and cut out a mount for some high flow fans. The picture is not what amp you will get, The one that comes in does not have boost and cant find any pics of it online. removing the plate helped and the amp STAYED COLD with my fan >>>> WELP it was fun till if goes into protect mode without rca, you put in rcas it works on low you turn it up just a little BOOM protect and that is with 2 Sdr-10 D2 running 2ohms. the amp should of NEVER gave out for being a sundown product. >>>> not buying a 2nd one switced to skar rp 2000.1d amp and NEVER BEEN MORE HAPPY.

Works great but it took a while to get it dialed in.

I was surprised at the small footprint of this amp and how much power that this amp actually puts out I have these set with two CT sound 10 inch subs and they sound wonderful I am pushing about 980 Watts.

I have this amplifier in my truck wired to a Rockford Fosgate 10 inch dual voice coil wired at 1 ohm and it hits hard Only downside is it’s vary sensitive to engine noise so on your vehicle aftermarket radio you need a dedicated ground wire to the battery or to a separate chassis/body ground with no other electronics grounded to the same point And if you attach it to your chassis/body make sure u take the paint off all the way to bare metal then put diode electric grease all over the connection and bare metal so it doesn’t corroded/rust

Bought this amp for a car i was building in October 2025. Finished my build March 2026 and finally got a chance to hear it, but it keeps clipping even at low volume. I love sundown but this amp is not worth it. Unfortunately return window has passed. make sure you get the added protection if you want to gamble with this amp.

Like the title says, this is my 2nd one. The 1st one I bought was perfect! Loved it, performed really well for hours of driving, never got hot. Sold the vehicle with the audio in it. Decided to do the same setup in my new vehicle, because it really sounded so well. So purchased this same amp again. Hooked the amp wires up, while waiting on the sub to come in, so everything was ready to go. Got power to the amp, and within 5 mins, it was so hot I couldn't touch it. AND THERE WASNT EVEN A SUB IN THE CAR YET! definitely had a heatsink issue of some sort. So I returned it. Not sure if just this ONE is defective, or if there's a bad line of them. 50/50 shot I suppose. Good luck

Excelente producto, lo volvería a comprar si fuera necesario
