I built this speaker using this amp on 4x12v 10AH batteries in series for 48v. I blew the rotary dial I had on the horn. I also made the sub get warm durning my testing phase. The range is outstanding. Inside this box is betting like 40yrds on range as long as my phone has a straight view.

Power house of sound. I used mine for a mobile install on my e bike. Ran six Memphis audio speakers, 2 -6x9s,2-6.5 component set, and 2-5.25 ran in series with a impedance of just under 3. Oh and a skar evl 6.5 dual 4ohm sub. With the battery I used this thing makes people turn around from over 600 yards away, INSANE!!!

This is a great little amp. No static on tuning knob. Plenty of power to drive my selected speakers (4 - 3in Magnadyne 50w speakers and a 5 CORE 12in 1200w subwoofer(WF12120)) in a custom enclosure using a 48v power supply.

This amp is for my shed/shop/cave sound system. The idea was to mount it vertically to the back side (along with the power supply brick) of a piece of sanded 1/4" plywood in between the studs with the controls facing out near the wall mounted tablet for easy access. The amount of power (48V 10A brick) seems more than adequate for this setup as I'm not looking to annoy the neighborhood with an obscene amount of output. I just want a nicely dialed in system with a fairly flat frequency response that extends down to my subwoofer's tuning frequency, hence the decision to go 2.1 channel. The board seems well made (not sloppy and with decent capacitors). If you pay attention, you'll notice that a lot of these Class D board amps prioritize signal routing and packaging/board population over standardization of control layout. Maybe I'm picky, but for as long as I've been dealing with the world of audio, the frequency range (from spectrum analyzers to graphic equalizers) has always been represented with lows on the left, mids in the middle (if present), highs on the right. I appreciate the fact that this board has the tone controls properly positioned with bass to the left of the treble adjustment. I really like the front panel and how it's labeled, so swapping the surface mount treble/bass pots isn't really a solution unless one discards the nice front panel as well. Now on to why I deducted two stars (and unfortunately will be returning this board). The board has been on the test bench a few days now as I layout my wiring and sort out the speakers and enclosures, etc. It was only after I had both channels and the sub hooked up that I realized the main flaw of this unit. It lacks a master volume knob. The two sides of the amp are not at all integrated, and operate as completely separate amps. In other words, you can not simply blend in your sub to the main channels and then use the main volume knob as your system volume. I had everything dialed in for just a few moments of enjoyment and then my phone rang so I quickly turned the volume down to almost nothing and grabbed the call. To my dismay, I found the sub still going strong at its original level, which I had to turn down on its own. It turns out Dajunguo calls this lack of master volume "feature 1". Essentially, this means you upset the sub/mains blend every single time you adjust the volume for any reason. Upon realizing this, I reached out to the seller via chat to find out what my options are and after rejecting their suggestion to simply use the tablet volume upstream as the master volume since digital volume controls work by decreasing bit depth and thereby raising the noise floor to audible levels, I was pointed to the ZK-AS21P-W. It is supposed to be an equivalent board I should go for if I wish for the main volume to act as the master volume controlling the output of all three channels simultaneously. It's worth mentioning that only the "P" variant of the AS21 board is equivalent to the S600X and handles up to 50 volts. This morning, I walked into my shed to find the board in the off position (just as I left it last night) but having heated up to an extreme level where it was too hot to touch with bare hands! I hope one is not expected to unplug the brick every single time it isn't in use. The brick itself was not hot at all. The board turned on sending a loud thud through the sub followed by a loud crackle through the mains, then the fan kicked on and it cooled down to normal operating temperature within a few minutes. So, this knocks off yet another star. The only other annoying feature (which can be bypassed/tweaked and password protected with the Wuzhi App) is that despite the manual saying that bluetooth is bypassed when the 3.5mm aux cable is plugged in, the board still reverts away from the aux each time it is power cycled, requiring multiple presses of the main volume knob. I understand the other option is to unplug and plug the aux cable back in after power up for auto aux switch to occur. In other words when the manual says there is no way to shut off non password protected bluetooth other than plugging in the aux cable, they mean you have to power the board on and then plug in the aux cable to avoid the board grabbing your neighbor's bluetooth device as opposed to assuming that leaving the aux cable plugged in prevents the board from broadcasting that it's ready to hook up to any device with no authentication in its current range. All in all, these boards keep getting better and better with every iteration, so I'm hopeful that the next version will have at least some of the above mentioned bugs/annoyances worked out. UPDATE: I ended up realizing I was actually missing some items from the package the day after I had posted this review. So, just coming back here to say that customer support has been nothing but top notch! Yes, this means two stars deducted due to features of the amp but a bonus one added for customer service! :)

At first I doubted this 600 W claim on the subwoofer channel. Until i connected a sub with a 400 W peak power at 1ohm. And I accidentally blew it so that was pretty cool. I needed to upgrade that either way. All in all, this is a solid amp. I love the fact that the subwoofer volume is different from the main volume. I'm

It works as soon as connect everything the only down fall. It has is that it can’t connect to a eq on the phone so u can tweak the highs and lows Another down fall I have is that the amp produces power and sounds clean but it does not really go high on volume my xk-as21 with 220 watts for left and rite channel and 330 for the sub hits good and it’s way louder then the new amp I just bought but over all good amp let’s see how good it last
