It seems like I looked at every mini 2.1 amplifier here at Amazon, 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 Amazon. The Kinter K3118-2.1 is light, yet sturdy feeling, and, in my opinion, is the best looking mini amplifier here at Amazon. 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.

Powerful to run two Bose rotating cube speakers with more than enough audio volume. Love the many ports, Bluetooth, USB, RCA, even another set of speaker ports to run a subwoofer. The only subwoofer that I could find to be small enough for this computer (or TV) setup is for a car stereo system and I need to make a box to install it into. Have not done that yet but the options, power, sound quality and very reasonable price point (far less than a NY strip steak at a steak restaurant) make this amp a no brainer. Forget those cheap computer speakers and instead buy better quality small sized passive speakers to use with this mini amp. Also - it is so cute it makes you want to buy several just to look at. Makes a fabulous gift for a teen or young adult away at college. Easy to install, bought an RCA to 3.5 headphone cable to attach to TV or laptop.

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.

For Christmas I fixed up this old turntable/radio cabinet for my parents by putting a new turntable in it and replacing the speakers (with some Pioneer car speakers). I could have driven the new speakers with the original amp built in to the radio but it was pretty weak (only 16w per channel) and I thought a new amp would sound better. So glad I went with this one. This amp was small enough that I could tuck it into this little nook inside the cabinet where you were intended to store records. Left enough room to spare to hide a cd player in there with it. Sounds great. Gets quite loud for such a little amp. Doesn't feel like it gets too hot, either, which was a concern given the low ventilation of the nook where I stashed this thing. Kinda wish it had a third input, but I made do with some radio shack adapters. Bluetooth is very nice, too. Pairs fast and easy. Highly recommended if you need a small amp for a project like this.

If I hadn't dropped the first one, I would not have had to buy the second. However, this small package is powering two outdoor Kicker speakers for my patio. The sound is really great. I wish it had a remote for easier control but that was my oversight. I installed it in a location that makes it simple to turn on and off. The bluetooth works flawlessly and pairs quickly. For the price, it does exactly what I needed for the outdoor living space.
