Kinter K3118 Digital Audio Amplifier - American Designed and Engineered for Versatile Applications Including DIY Projects, Arcade, Home, Auto & More! Texas at Heart Inside the Kinter K3118 amplifier is a USA Designed Texas Instruments (TI) TPA3118 Class D audio amplifier IC that provides 2 X 15 watts RMS of highly efficient, detailed audio that's perfect for desktop, workbench, garage, arcade, auto, cycle or DIY projects. A Versatile Performer Separate Bass and Treble controls are standard on the K3118 amplifier as are gold-plated RCA left and right inputs along with a 3.5mm jack for plugging in smart phones or other equipment as the audio source. A β€œDirect” button bypasses the Bass and Treble circuit for listening to unaltered sound. The volume control is surrounded by a blue light indicating the amplifier is on. Connect your 4-8 Ohm speakers using the 14-16 gauge spring-loaded terminals found on the rear of the amp. The small aluminum enclosure keeps the K3118 running cool and has tabs that allow the amplifier to be mounted if required. Anywhere and Everywhere The K3118’s TI based Class-D design makes it an extremely efficient amplifier, and with upwards of 90% power efficiency the K3118 will sound larger than expected while generating less heat, and if operated by a battery will last longer, making it perfect for portability. Capable of operating between 4.5 – 24 Volts DC makes the K3118 ideal for most any application. Best of all, a 12 Volt DC 3 Amp power supply is included. Please Note : The included power supply is capable of driving this amp at 2 x 15 watts per channel. To realize the full potential of this amp (>20 watts per channel), we recommend a power supply 15 to 19.5 VDC, 3A (minimum) that is capable of producing up to 60 watts of total output. Performance-Based Features Combined with the Ultimate Support and Affordability An Original USA Design With so many "no name" and questionable amplifiers in the market today, you can rest assured that the K3118 has the pedigree for solid audio performance. Led by USA Texas Instrument Engineering and quality Kinter Manufacturing, the K3118 is the combined effort of two teams working to bring you the best choice as the most affordable, efficient and quality audio amplifier for your listening needs. Easy Connections Quality Gold-Plated RCA Left and Right connectors and a 3.5mm audio input provide simple connectivity to TVs, Gaming Devices, Smart Phones and more. Improved spring-terminal speaker connectors accept 14-16 gauge speaker wire, simple press and insert bare wire into the slot. NO Frustrations! When you have questions it shouldn't require extra effort for you to get a clear explanation and accurate answer. In addition to Spanish Speaking and other international support staff, we maintain Native English Speakers that can offer technical assistance via email or are happy to call you with the answer to your question or application issue. Power Included All the Features You Need! Overview and Specifications Getting started is easy with the K3118 Amp. First, plug in the included 12 Volt 3 Amp power supply, connect 14-16 Gauge speaker wire between your speakers and the spring loaded terminals on the back panel, connect a source device using either the 3.5 mm MP3 input or stereo RCA jacks, turn the power switch to ON and the tiny Kinter 3118 Amplifier is ready to go. Using the separate Bass and Treble controls you can customize your sound, or push the "Direct" button to bypass the Treble and Bass to listen to source audio without any modification. A large front knob controls the volume and is surrounded by blue LED lighting. Mounting tabs found on the sides of the K3118 amp make it great for DIY projects or other applications where having a fixed location is required.

Review: Unbelievable Sound on a Budget! - I recently found some hidden gems at Goodwill - a pair of bookshelf speakers in need of a worthy amplifier. After scouring the market for an affordable option, I stumbled upon these gems. Not only were they the most budget-friendly amplifiers around, but they also boasted the credibility of a name brand op-amp, Texas Instruments! To be honest, I didn't set my expectations too high, but oh boy, was I in for a pleasant surprise! This amplifier exceeded all my assumptions and then some. At this price point, it keeps things simple without unnecessary frills, but let me tell you, when I compared it to my $600 Yamaha Amplifier in "Pure Direct" mode (which essentially means no Yamaha DSP magic), this little powerhouse held its ground remarkably well. The music reproduction is phenomenal, matching the performance of its much pricier counterpart. The clarity, depth, and overall sound quality left me in awe. I can't stress this enough - for the price, this amplifier delivers an astounding performance. If you're on the hunt for an affordable yet impressive amplifier, look no further. This is the real deal, providing exceptional value for your money. Don't miss out on the musical magic this amplifier has to offer! Highly recommended!

How is this done?** A: The full statement they make is, "To realize the full potential of this amp (>20 watts per channel), we recommend a power supply that is capable of producing 60 watts of total output." What they are getting at is that the included power supply is a 36-watt supply (12V X 3A = 36W). To achieve a higher power output, use a power supply greater than what they provide. If you stick with using a 12V supply and you want 60 watts out of it, you need a 12V 5A supply (12 X 5 = 60). However, you don't need to limit yourself to a 12V supply. The unit will operate with a power supply voltage between 4.5 – 24 Volts DC, so any power supply within that range will work if its current (amps) will allow 60 watts. To determine that, divide 60 by the voltage and that will tell you how many amps it needs to deliver. For example, a 5-volt supply would need to deliver 12 amps (60 / 5 = 12), a 24-volt supply would need to deliver 2.5 amps (60 / 24 = 2.5), a 15-volt supply would need to deliver 4 amps (60 / 15 = 4), and so forth. Just make sure the power supply has the same 2.1mm x 5.5mm plug as the original to fit the input of the amp. **Q: Is this amp bridgeable?** A: No, this amplifier is not bridgeable. **Q: Can I just cut the ac plug head off and wire the plug directly to my boat's 12v electrical system?** A: You can cut the cable off the power supply and use it, but why not just buy a 2.1x5.5 plug, wire it yourself and save the power supply for something else? ## Customer Reviews ### ⭐⭐⭐⭐⭐ Unbelievable Sound on a Budget! *by T***E on February 10, 2024* I recently found some hidden gems at Goodwill - a pair of bookshelf speakers in need of a worthy amplifier.

Room sounds great! ### ⭐⭐⭐⭐ Tests at 7 watts per channel, but works well for PC Audio *by M***S on January 18, 2024* Someone gave me a small pair of speakers, and I needed an amplifier to drive them. Before putting it in service, I tested it into a dummy load on a Rohde & Schwarz UPV audio analyzer. Frequency response is reasonably flat. The tone controls give a lot of boost and modest cut, which is nice for getting more body to the sound on small speakers. The continuous RMS power measured at clipping is 7 watts per channel. I would imagine the power brick is the limiting factor. Overall, a nice little amp that uses almost no juice when idle and is adequate for computer sound when I want to watch a video online. ## Frequently Bought Together - Kinter K3118 Texas Instruments TI Digital Hi-Fi Audio Mini Class D Home Auto DIY Arcade Stereo Amplifier with 12V 3A Power Supply Black - BOSS Audio Systems BRS40 50 Watt, 4 Inch , Full Range, Replacement Car Speaker - Sold Individually - Amazon Basics 16-Gauge Speaker Wire Cable, 50 feet, Transparent --- ## 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.uk/products/63406764-kinter-k3118-texas-instruments-ti-digital-hi-fi-audio-mini](https://www.desertcart.co.uk/products/63406764-kinter-k3118-texas-instruments-ti-digital-hi-fi-audio-mini) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-07*
