Solid clip light and no power output whatsoever. My wiring is beautiful and better then most people's I've ever seen too lol. Hoping the "warranty" that the "shop" I bought it from will be honored through Sundown. The audio shop told me I had to go through them.

@@theevilshred5567 was your eltrical up to par to support the Amp if it wasn't then we know why

[@wow1022]

one of the main things that the full bridge design (aka H bridge) eliminates is the need for a negative voltage rail since the operation of the PWM of the H bridge basically constantly flips the polarity of the modulated square wave across the output filter and speaker, this simplifies power supply design mainly, nothing new, it's just has a bit more complicated PWM and requires more FETs

[@________GHOST________]

I do not know how many times darek ( I do not know if I spell your name right my bad) is going to explain the SFB amps like this again. To many bassheads with no sense at all do not listen or pay attention at all WTF LOL :D DO THE RESEARCH ON FULL BRIGDE AMPS SIMPLE AS THAT.........

[@Bmahlke1]

I see this question still has not been answered, I will ask it again. Compared to other full bridge amplifiers, at what rca input voltage do these perform their best at? Many other brands with this similar topology have been proven to clamp more power at 2v rca input voltage vs running it higher than that. I've tried giving my sfb 8000 around 2v or so and as well around 4.5-5v, using the 80prs as the source unit. I haven't noticed much difference, but I also have not done enough testing to justify at which voltage the amplifier prefers. I'd greatly appreciate input on this topic, as many of us who are running this line of amplifiers probably have the same question. Thanks

[@Es0ter1ca]

Bring the SA-12 woofer test part 2 already!!

[@mikeunivers]

The topology of these amplifiers only share the full bridge, in what they differ the most is in the type of rail they use, sundown uses a double rail, eg:+ - 70v and the Brazilian amps use a single rail, that is, a 160v rail, What if they seem to share is the use of a control chip that is in charge of source oscillation and amplification oscillation. In addition, they share the high frequency of oscillation in the amplification phase and this is what makes both amplifiers so efficient.

Sundown - Can the internal crossovers be used as a bandpass for output to a subwoofer? Can the high-pass be set at 15hz/ 20hz (shallow subsonic filter) and still use the low-pass crossover at 80hz and down for the output to the subwoofers? Or does the HP crossover just control the filter for the RCA output jack to a separate amp? Thanks!

Question on how to set the high pass and lowpass filters when running the sfb amps on subwoofers? Thanks for videos and all the info.

[@Thezuule1]

You ever figure it out? On mine I just set both to the lowest setting. Low pass starts at 80hz according to the printing on the amp and the high pass starts at 15hz. So that drops anything below 15hz and above 80hz which is right in the range I want for my SA 12v2. I was scratching my head a minute from the lack of a crossover switch when I first got it but it sounds good this way which is good enough I suppose.

How is the sound quality korean vs fullbridge.

[@RomaVilla]

I had the sk1500.1 and I ran that amp at 0.5 ohms and it took it like a champ. Pushed my 15 zvx pretty hard and sound quality was actually pretty good at such a low ohm load. Did get a little warm but then again it was at full tilt and it was efficient at 1 ohm and half ohm all day long. So Korean amps are just built better all around vs a full bridges and full bridge cant run under 1 ohm and the sound quality starts to really y suffer once you go below 2 ohms so it's more of a preference because the sfb 2k can run highs, mids and subs so there is an advantage when it comes to full bridge amps. Just my 2 cents though.

Made in China. So, Should I expect a noticeable sound quality loss? In a subwoofer config, SCV-2000D vs SFB-2000D, I doubt you'd notice a quality difference - Bass is bass so long as its pure.

[@TheBaZooKa115]

My amp keeps going into protection mode

[@wow1022]

and a full bridge design could technically push the same current as the SCV line's half bridge with the correct selection of FETs, i have noticed that the SFB uses the smaller TO-220 style FETs in the power supply rather than the bigger TO-247s like the output section uses, which I find interesting, the SCV line uses all TO-247 style... this may be part of why the amp shows high power at higher ohms, but hits a limit on power as you lower the impedance, as the power supply's rails collapse as more current is drawn from the amplifier section.... which isn't necessarily a bad thing as that allows more power as the impedance rises during play

[@ampaddiction]

I just received one of these amps. This may be a stupid question, but from the few amps I have ever owned there were always fuses on the amp. I see no fuses. I have a fuse at the battery. Am I supposed to wire fuses myself near the amp also? Sorry but I did not get an owners manual in the box.

How much can I turn the gain up on the amp because I was told if my clip light comes on it will be fine considering the amp?

[@jasonerosewrx]

You talked about putting to much voltage to the SFB. What would be the lowest you would want your voltage to drop to while pushing it full tilt?
