Review: The Mini Amplifier With The Big Attitude - It seems like I looked at every mini 2.1 amplifier here at desertcart, but none of them brought as much to the table for such a reasonable price as this Kinter K3118-2.1. The amps in the $25 - $35 price range are either just circuit boards or sandwich type cases (both of which look like high school science projects to me), and the price for the amps in full aluminum cases jumps to $70 - $80 – with most of those still requiring the purchase of a power supply. At $40, the Kinter K3118-2.1 is the happy medium with a full aluminum enclosure, a 19V 5-amp power supply, and dual Texas Instruments amplifier chips that provide all the juice I need for my DIY 2.1 system. With its good looks, solid build, and quality features, I feel that this is the hands down best value for a mini amplifier to be found here at desertcart. The Kinter K3118-2.1 is light, yet sturdy feeling, and, in my opinion, is the best looking mini amplifier here at desertcart. Both the power switch and the BT/LINE selector switch are solid and durable feeling and click audibly in a highly satisfying manner when toggled. The separate control knobs for the subwoofer, bass, treble, and master volume have a “just right” feel of tension to them with no sloppiness at all. Basically, the switches and knobs have the same feel to them as the switches and knobs on my far more expensive audio/video equipment inside my house. The Kinter K3118-2.1 really impresses me with a level of quality that belies its low cost. It’s nice to feel like I got more than I paid for once in a while, and I definitely feel that way about this amplifier. Connection can be done via Bluetooth or line, and both work flawlessly. In 2-1/2 months of use, it has never failed to connect to the Bluetooth on either my android phone or iPad, nor has it ever dropped the connections. I don’t think I own any other Bluetooth device that I can say that about, so pretty darn solid in that department. The speaker connectors are of the spring-loaded variety, and they clamp down on my 16-gauge wire tightly and securely. An interesting aspect of the K3118-2.1 that I didn’t see on any other 2.1 amplifiers is that the subwoofer is connected by bridge mode versus having some form of dedicated plug to facilitate the process. This is really neither good nor bad in my book, but it does require a little more work to make some splices to get a subwoofer connected. PRO TIP: I am using low voltage landscape wire instead of actual “speaker wire”. Braided copper wire is braided copper wire, and low voltage landscape wire or lamp wire is much cheaper than “speaker wire”. I built my speaker cabinets out of 1/2-inch MDF and used 8-ohm DROK 3-inch woofers along with these surprisingly great sounding no-name 6-ohm 3/4-inch tweeters wired to Uxcell crossovers for my mains, and an 8-ohm 6-1/2-inch Dayton Audio DC160-8 for my subwoofer. According to the product description, I lose 10 watts per channel using 8-ohm speakers instead of 4-ohm, but 20 watts per channel is fine enough for me, and I prefer the lower heat generation of 8-ohm since this system is in my garage. The sound quality far exceeds my expectations, and I rarely turn the volume knob past the quarter mark to fill my 20 x 25 garage with crisp highs, solid midrange, and some satisfying low end punch. Movie soundtracks are also quite a surprise with sharp, clear dialogue and deep rumbling bass during explosions. The Kinter K3118-2.1 appears to be a high quality product that provides a lot of bang for the $40, and warrants serious consideration for anyone building their own mini system.
Review: Performs way beyond its price - I'm not usually one to leave reviews, but this little amp has impressed me so much that I felt it deserved it. Last year we added a new back patio on to our home, and one of the upgrades we included was an outdoor audio system. While shopping for components, I couldn't justify the costs of some of the ready to go wireless/bluetooth audio systems I was seeing, so I decided to piece my own system together. After lots of research and google-fu, I decided to go with this Kinter amp for a few reasons: compact form factor, Bluetooth and wired input ability, and sufficient power output for my needs, and cheap enough that I wouldn't be upset if it didn't survive outside. I paired this up with a set of Polk Audio 8" outdoor ceiling speakers, and all in I'm only about $350 into my outdoor audio setup. All I can say is this combo has blown me away. Using my phone as the BT audio source and volume set to 50% on my phone and 50% on the amp, it's more than loud enough for us and crystal clear audio. If I turn my phone up to 100%, it's unbearably loud on the patio, and my neighbor that's more than 100yds behind us can hear it easily. I'd honestly be scared to know how badly it would blow my speakers out if I tried to go a full 100% on both ends. This thing has been going strong living it's entire life outside for the last 8 months, and has given me zero issues so far. I plan on picking up another one of these soon for the audio system I'm going to be installing in my workshop too.

## Questions & Answers

**Q: How would I connect a passive subwoofer with two wires? Does this have instructions for this type of setup or does anyone know?**
A: There are connections on the rear marked "SUB". There are two + (red) connectors and two - (black) connectors. The instructions say that if you only have 1 subwoofer speaker (common), then connect the two red connectors together and connect them to your subwoofer. Also, connect the two black connectors together and then connect them to the other side of you subwoofer. They recommend wire nuts to make the connections.

**Q: Does this amp have a voice? i currently have a douk audio amp that screams at you in broken english… i want to replace it.**
A: BOY do I feel your sentiment here. There are some great budget amps on Amazon but so many of them have some stupid try-hard asian or British voice that's LOUD AS HECK and completely ruins the experience. I have to say, I've bought so many amps on amazon, including brands like DROK, kinter, Dayton audio, and lepai, and this particular amplifier from kinter is SUCH a gem. Just a simple, iphone like notification tone plays when Bluetooth connects or disconnects,.and that's it!! No annoying voice, SUPERB sound quality, and a great price. I'm waiting SO eagerly for this amp to be back in stock! I can't find them ANYWHERE else!! I found some on a Chinese manufacturer to consumer website but when they arrived it turned out they were an older model without built in Bluetooth! Still works just as well with a good choice of Bluetooth receiver, but the Bluetooth version is just so amazing to have and use. I'm very picky with the speakers I build and this thing is just amazing. Sorry for the long answer, I like this amp too much, but the answer to your question is no, no annoying voice on this wonderful amp.

**Q: Sound quality equal to the 2020A+ limited? I like the 2020 but it has no sub out**
A: The TI 3118 Chipset is probably the closest thing you will find to the 2020 in Class D amplifiers.  The 2020 does have a very unique  sound quality that's difficult to replicate.

**Q: Will this be enough power to run the passive subwoofer in home theater setting?**
A: I have a passive subwoofer from a Samsung home theater system that this amplifier runs. So far I haven't had any issues.

### ⭐⭐⭐⭐⭐ Performs way beyond its price
*by R***. on January 19, 2024*

### ⭐⭐⭐⭐⭐ Small amp. Big sound. Flexible control. Perfect for my need.
*by K***R on March 8, 2025*

This tiny amplifier does exactly what I need and has a true 2.1 configuration and plenty of power so I felt compelled to write a long review on this unit. I hope it helps. I plugged in three different 2-way bookshelf speaker pairs - Boston Acoustic CR6s (8 ohm), Yamaha ES-E55s (6 ohm), and Bose Double Cubes (4-8 ohm) - plus three different 3 ohm 8" passive subs - Sony SS-WSB103, Samsung PS-CW0, and Samsung PS-FW102 (4") (side note: all subs were thrift store buys) - and all made good sound via iPhone thru the quickly connected Bluetooth signal. I did not try the component piece since my use is Bluetooth. Just for kicks, I doubled up the 2-way pairs (4 speakers out of the top row) and doubled up the subs (2 subs out of the bottom row) and the amplifier powered everything just fine. I ran the various configurations for about 2 hours at thumping volume with folk, rock, hip hop, and metal and all sounded great. I settled on the best sound for me (it's all subjective) with the Bostons and Sony. Don't let the 30 watts per channel make you believe it will be too small or not powerful enough. I'm betting a mid size or maybe full size pair of speakers would sound good too. A big pro, as noted, is the 2.1. The sub channel is a true sub channel and not a "B" pair of speakers (I plugged in a pair of the 2-ways to the sub ports and it wasn't right at all). Use only a sub in the sub ports. A huge pro, maybe the best part of this amp, is the sub has it's own volume control so you can thump or just allow subtle fuller lows. Lastly, the amp did not get hot...at all. You can put it anywhere...except...the amp doesn't have a remote control so it's manual on/off and manual volume, sub volume, treble, and bass control. Place it within reach. That's mostly fine with an iPhone controlling volume but it should still be shut off. A remote would have made it 6 Stars for me. With every rating, I add the caveat it's only been out of the box for a couple of days and ran a few short hours. I have faith it will last and/or Kinter will make it right if it doesn't.
