## Questions & Answers

**Q: Will this work with powered subwoofer? Passive suboofer?**
A: A Passive subwoofer would be my recommendation, the passive subwoofer depends on an external amplifier and this would be the external amp. If you use an Active subwoofer; it contains a built-in amplifier and the result would be overpowering the subwoofer and you will get adverse effects

**Q: Does the amp have a fuse?**
A: Your question does Not specify your concern for a fuse on the Power input or on the Speaker Output section ? 
Answer: 
No fuse at all, the circuit with a 12 VDC 2 amp or above 18~24 VDC Power supply adapter does not get warm at all; it has a very good Audio quality response as well as the Output Power volume for its size. It is an excellent amplifier. with 12VDC supply - 15Watt Output Power up to 24VDC supply - 50Watt  Output Speakers Power and the Subwoofer power Output ranges from 20W ~ 100W output Power depending on the Power supply input.

**Q: how high does the subwoofer lowpass go? Can i push it up to around 500hz, or does it stop at, say, 150hz?**
A: It can't 500hz, only be used in the range of 20-200hz.

**Q: Are the main L&R speakers full-range or high-passed? If they are high passed what is the cutoff frequency?**
A: Both channels are full range, with separate bass/treble controls. I don't know what frequency the controls are biased at.

## Customer Reviews

### ⭐⭐⭐⭐⭐ So far, so good
*by C***S on July 8, 2023*

So far, I like this little amp. It came packaged well: small box with a disassembled unit that you put together. I'm a tinkerer, so that's perfect! It was easy to assemble. Took less than 5 minutes. It has a 3.5mm stereo jack or blue tooth for pairing to a phone. I tried both and they worked well. Sound quality is good, albeit I don't have my speakers mounted in a box yet, so I'm hoping for a marked improvement. All in all, I'm happy. If you're expecting high end perfect performance, you probably want to go with something more costly. If you're building a simple stereo project for the fun of it, try this out. It's cheap, small, and funCON: didn't come with a power supply. I received some advice from others and ended up powering it up with an old 12v 3.5A adapter from my old Netgear router. It worked! I'll get a better 12V or 24V 10A supply later.

### ⭐⭐⭐⭐⭐ Gave new life to some old stereo speakers
*by A***E on October 23, 2023*

I had two shelf speakers and a sub from an old stereo system that the original head unit died out. The speakers sat in storage for a year before I dug them out and tried hooking them up to this amp. I am VERY pleased especially since the price was so low.Bluetooth works great but doesn't have very much range. My apartment is small enough it doesn't matter much. Sound is really good but I've only used about half of this amps power.I used a 12v power supply to power it. I wanted to use a 24v since the amp can handle it, but every time I plugged a 24v into it the amp would spark at the connection point. Didn't feel like accidently burning my place down so I stuck with a 12v

### ⭐⭐⭐⭐ Great value amp, but it comes with a few cons!
*by F***Y on August 22, 2023*

FIRST AND FOREMOST! YOU HAVE TO POWER THIS AMP WITH 20-24V FOR FULL VOLUME AND MINIMUM DISTORTION! I can't tell you how many reviews I have seen for amps using the TDA311x chips where people complain about volume and poor sound quality! If you plan to buy this amp, be sure to power it with 20-24v! If you power it with anything lower, the maximum volume before distortion is not very loud and bass will get muddy very quickly!I bought this amp to replace a similar one from another vendor that I managed to water damage. The components on the board are very similar to other TDA3116D2 amps I have seen on Amazon, but I will only speak for this one in particular.CONS:1. The terminals used to connect the speaker wires are small and the screw goes right through the center. This means that if you use wires that have ferrules on them, like mine, they don't fit. You either have to use bare wires that are prone to damage, or use some pliers to smash the ferrules to be flat enough to fit into the terminals. I don't know if any spade connectors exist that are small enough to fit into the terminals on this amp, but if they do that is probably the better option.2. When putting the cover plates on the front and back of the amp, I had one small brass standoff that was not threaded correctly. It would immediately screw in crooked into the long brass standoff. All of the other standoffs worked as expected. I had to force the two together and hopefully I don't have to remove them at any point because they are definitely cross-threaded now.3. The bluetooth range is TERRIBLE. Seriously, I use this thing amp outside and I can't be more than 10ft away WHILE maintaining line-of-sight before the audio cuts in and out. If my phone is in my pocket and I am standing 5ft from the amp, it can randomly cut in and out. If I put my phone on the ground or on a table next to the amp, it still can randomly cut in and out. I don't understand how the range can be so bad, but it is awful and honestly quite irritating at times. I've given up holding my phone while listening to music with this amp, it is a bad experience.4. The master volume knob is very touchy. My speaker is already at the limits of what it can handle with the knob about 1/4 of the way up and barely moving it changes the volume significantly. I have resorted to leaving the knob at 1/4 and controlling the volume through my phone or through the AUX source instead.5. The only bluetooth codec that this amp seems to support is SBC which is arguably the worst sounding and least technologically advanced of all of the codecs on the market today. It is probably fine for most people, but there is a noticeable difference in quality when using the AUX input instead of bluetooth. I would have loved it if this amp supported higher quality codecs such as AAC, aptX (and its variants), LDAC, or LHDC/LLAC.PROS:1. With 20-24V input (I've used both a 20V USB-C to barrel plug adapter and a 24V barrel input), there is more power than my speakers can comfortably handle (my ears too) while maintaining good clarity for an SBC bluetooth codec. When using AUX as the input, the clarity is even better though you may end up with humming and buzzing issues if your AUX source also gets power from a wall outlet. That is what happened with the AUX input from my desktop computer so I had to build a custom cable with audio isolation transformers for the two stereo channels. Once I did that, no more humming or buzzing.Overall, despite the multiple cons this amp has, it is still a great value for the money. In the right use case, this can be a great fit offering great power output, high efficiency, and small footprint.
