## Questions & Answers

**Q: Can anyone provide specs on thd, snr, frequency response, etc?**
A: Specifications: • Power output: 2 x 20 watts RMS • Speaker impedance: 4-8 ohms • SNR: >102 dB • Input impedance: 47k ohms • Frequency response: 20 Hz - 22 kHz • Input sensitivity: 200 mV • Minimum THD: <0.1% • Dimensions: 4.72" D x 5.79" W x 1.65" H.

**Q: To realize the full potential of this amp (>20 watts per channel), we recommend a power supply. 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. 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!

### ⭐⭐⭐⭐⭐ Highly recommended for its purpose - quality moderate-power amp
*by E***H on October 1, 2023*

For what it costs, this is a total no-brainer if you're looking to power a single stereo channel with moderate power (wattage). Sound is very passable - and the tone controls help here. Great input section (both RCA and 1/8" jacks), and the blue light isn't obnoxious.For $20, this is simply an incredible value. I installed it as a sub-zone amplifier for a whole-house controller, allowing me to use fixed volume for the line out on the controller to pass signal to this amp and use a set of speakers for which we didn't have a dedicated controller channel. It works perfectly and drives the speakers (located outside) very nicely at about 30% on the volume pot. Such an elegant solution all around.

### ⭐⭐⭐⭐ Nice and Compact Little Amp.
*by V***S on January 29, 2025*

I mainly purchased this mini audio amp to replace the one I currently have because of buzzing noise it was making for the living room TV. It sounds better without that annoying buzz and does the job well. That's why my living room TV sounds better when I hooked it up to the RCA audio output behind the TV.
