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. Review: exceptional amp - This little fellow solved my problem perfectly. I needed a unit to which I could attach wired speakers to use with my computer, and after three futile research attempts I came upon the Kinter unit. I needed clamps to attach the speakers and this unit has four. Attaching my speakers, holdovers from a shelf stereo, was incredibly easy. I connected my computer to the unit through Bluetooth and voila! Beautiful sound, much better than the smaller computer speakers I was using. Kinter sent the item quickly and I was back in business. Wonderful amplifier.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Performs way beyond its price *by R***. on January 19, 2024* I'm not usually one to leave reviews, but this little amp has impressed me so much that I felt it deserved it.

Wonderful amplifier. Small, but with a powerful punch... ### ⭐⭐⭐⭐⭐ Awesome amplifier that will surprise you! *by S***! on March 15, 2025* I have to admit, I was a little skeptical about this amplifier, then I set it up. I am currently using this as a custom solution for a desktop sound system. I am using a Sony 3.1 desktop bookshelf speaker system with a Sony 10 inch woofer and it sounds amazing. To get the center channel, I bridged left and right speaker outputs (one positive, one negative) to the center channel speaker. This amp is very stable at 4 ohm loads, so bridging two 8ohm speakers with a third in the middle leaves a 4ohm load on the front channel which does not even cause heating or clipping even at the ridiculous volumes I enjoy. Also, having the dedicated passive subwoofer output is awesome, it even has its' own volume control so you can finitely dial-in the right amount of bass for your setup. For the price, you cannot go wrong with this amp. It may look small, but it really delivers in desktop or bookshelf applications. I have used this to drive two Paradigm 9se 4ohm tower speakers as well, and again, this little amp drives those huge tower speakers with no struggle. Bluetooth works well, and the line-in features are either RCA inputs or the standard headphone-type input, which is awesome if you are running linbe-out from your PC or laptop. I highly recommend! ## Frequently Bought Together - Kinter K3118-2.1 Bluetooth 5.0 Stereo Digital Receiver Amplifier 2.1 Channel Mini Hi-Fi Class D Amp 30 Watt x 2 Channels + 80 Watt Subwoofer for Home TV DIY Auto Outdoor Passive Speakers Subwoofer - Amazon Basics 16-Gauge Speaker Wire Cable, 50 feet, Transparent - Dual Electronics 4" 3-Way High Performance Outdoor Indoor Speakers with Powerful Bass, Effortless Mounting Swivel Brackets, All Weather Resistance, Sold in Pair, LU43PB --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/292484881-k3118-2-1](https://www.desertcart.co.th/products/292484881-k3118-2-1) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-11-03*
