I like it so far. Definitely plenty of power compared to the MT21. Im also using a 36v 11a power supply with this. One thing i don't like is that you have to disconnect the aux cord to use bluetooth mode. But other than that its a nice little amp for the price.
I'm curious what you think is worth $15 - $40 like the amps you showed in the video. I think they are a bargain and they are perfect for a micro system. Much better than buying a used receiver with all those features and DSPs nobody uses.
Yes these mini amps are great, but they do lack some features that would greatly improve them. Just something simple like an actual EQ, maybe a 7 band atleast. Bigger input wires for power/ground and optical or something like that would be nice too. For the price, I think the HT21 is perfect. Especially if you've got a power supply big enough to support it. For a cheaper solution, I'd just go with the TPA3116. It's a solid chip and the Wuzhi company has a few variations. Hope that helps, let me know if I can do anything else.
These are 2.1, so two channels for speakers and 1 for sub. Unless you mean how the sub channel has vocal bleed, then yes, something like an 80hz filter would be fine to wire inline
Dude wtf I got one 3 weeks ago and I haven't heard it yet because it keeps saying you need app for it. And you can't find it. And here you are with the same amp and you don't need a app to connect to it. Congrats. Wtf
You can find the app through Google, on a random forum lol. It's a bit tricky, it's not on the app store. But you don't want to use it, it tries to run in the background and shit like typical China Spyware. But yeah you DONT need to use any app. Just power the amp on using a power supply and pair to your phone and you're good to go or connect with 3.5mm aux, whatever you prefer
Here is the link, you may be able to find a later version, dunno if there is one or not, but this is the ACTUAL app for Wuzhi if you really wanna use it www.diyaudio.com/community/threads/the-latest-version-of-the-android-app-for-wuzhi-amps.393439/
Hello, i use this adjustable 36v 11a power supply. If youre in the USA, watch my power supply video, if not, watch videos or read on which wires are for Nuetral, Line and Earth for wiring it up. Be sure to flip the switch on the side to 110v or 220v before turning it on aswell. Youll also need to take a multi meter and adjust the power supply to the correct output voltage. Since the Wuzhi amp has an operating voltage up to 36v. You need to adjust the power supply to 36v before wiring up the amp(power supply is adjustable from 23v to 38v). If you have any more questions feel free to ask all you want. www.ebay.com/itm/400W-36V-11A-Switch-Power-Supply-AC110V-220V-to-DC-36V-Power-S-400-36-CNC-Router-/293570750488?mkcid=16&mkevt=1&_trksid=p2349624.m46890.l6249&mkrid=711-127632-2357-0
I'm not sure, I've never seen/heard a JBL boombox3. I do know, if you give this amp proper voltage and have plenty of amperage to supply it, it will definitely out perform most booxboxes I've ever heard. Especially with these being 2ohm stable, you're able to wire a few speakers to it(if you had eight 8ohm drivers, you could run four per channel, such as PRV 8FR250's) and the sub channel is also 2ohm stable. And on my AS21P video, same with the HT21, give it the voltage and plenty of amperage most importantly, it will get damn loud. I use the AS21P in my work van, powered by four 9ah Makita batteries, wired in series/parralel(Waitley brand batteries, little over 36v&36ah), an all Sundown Audio setup consisting of Sundown e series 6x8 coaxials in the doors and 5.25 in the a-pillar, and then a 8" SAv3 in a transmission line and its loud enough to get ya in trouble with the cops needless to say lol. The HT21 is no slouch though and is my general recommendation on an amp to start with. Although if you plan to jam for long period of time at loud volumes, the AS21P may be the better choice, it has a much larger heatsink and the amp handles longterm loud volume well, just be sure to give it plenty of voltage/amperage as I said.
@@anuy453 the amp is supposedly a "540w" amp so you'd want a 600w power supply ideally but these amps don't do rated power, so a 300w power supply would be fine. Anyways, if using a 24v power supply, you would need atleast a 10a power supply. 24×10 = 240. These are rated up to 36v, so if using a 36v power supply a 10a would be more than sufficient and let the amp run a little more efficient aswell. Always good to run the amp at its highest rail capacity.
Yes, its noticeably louder all around and a good buy for the price, ofcourse given you are using an adequate power supply. I use a 36v 11a switching power supply, runs around the same price as the amp and is in one of my videos(check the video list). A downfall is that although its much louder, you still only have treble and bass adjustments for your speakers, so with all that extra power its kinda harder to dial the amp in for a good balanced sound, unless you're the type who doesn't mind messing with the controls for each song. The subwoofer section is the same setup but i find the frequency filter still lets a small amount of vocals in no matter what but its not real noticeable. My setup has literally been on and running since i got it all setup a couple months ago and i blare music for long periods and never have any issues out of the amp, the built in fan works great. Hope this helps with your consideration of buying this amp.
HT21 is $40 here, could be nice to play around with. Proper power supply really helps.

Clean sound nice im gonna upgrade my 7498 to this 7498e
I will gonna buy this for my diy BT thanks for the review bro
Keep it up
Thank you. It sounds good and has plenty of power

Nice!
in ZK MT21 if wrongly place +/_ terminal it busted.....how about ZK HT21? just like big amplifiers it works ?
Ht21 will blow if you place +/- wires in wrong place
Can you use a crossover with this amp to keep a sub mono?
These are 2.1, so two channels for speakers and 1 for sub. Unless you mean how the sub channel has vocal bleed, then yes, something like an 80hz filter would be fine to wire inline

Is this amplifier equipped with a bluetooth receiver?
Yes, all the Wuzhi amps have a bluetooth chip inside that you can pair your phone or other device with to stream music too..etc

Can you send power cord info ? I ended up blowing up my last one .
It's a 19v 4.75a power supply off ebay. Just search 19v 5a power supply
how many inches is the subwoofer and how much does it cost?
Hello, its an 8" and is discontinued. Check out the SKAR AUDIO SVR. It costs around $70-$80 usd.

Ohm subwoofer speaker?
I am running the sub channel at 2ohm and speakers at 4ohm. Works great, no problem and no heat issues or anything.
What power supply you run
38v 11amp. Cage style power supply, can get them on Ebay for less than $40 or so.
