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.pl/products/63406764-k3118](https://www.desertcart.pl/products/63406764-k3118) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-26*
