Review: Great for a classic convertible. - It sounds great, plenty of power for my two 35 watt ms 4” speakers. Very discreet “bing” sound when the Bluetooth connects to my phone. Easy to assemble and install. Doesn’t get hot. Audio pauses when I get a phone call (call doesn’t go through the amp). Solid and stable Bluetooth connection. Perfect “hidden” stereo for classic car - I left the original, broken, AM radio in the dash for looks, and replaced the single 4”x10” mono center-dash speaker with two Infinity 4” Reference speakers rated for 35 watts RMS (105 max) 4 ohm each. This receiver has more power than I need, so I have it’s volume set at 60-75% of max. I get a small but sufficient amount of base (pleasantly surprised), and nice mids and highs. I like being able to adjust base and treble. No hiss or noise. It’s loving the 13 volts my car delivers. I’m very impressed with this little receiver. No complaints, and almost free. The downside to this setup is that I need to touch my phone to adjust volume, skip songs, use Siri, etc. Also, an incoming call will pause the Bluetooth, but not route the call audio through the car speakers, and there’s no microphone,so no hands-free calling. My solution was to also buy “Aston Innovations SoundTek A1+ Bluetooth Car Kit”, and plug it into the AUX input of this little amp. Then I use the Bluetooth of the SoundTek instead of the Bluetooth on the amp, and I have everything I want: 1) Original looking (but not working) 1966 AM radio in the dash 2) Streaming music through Pandora or Spotify 3) Hands-free calling where I can hear and be heard, and use Siri No AM/FM, but who cares. The SoundTek has a 1.6” round control pad that I can hide in the ashtray or wherever. Through it I can control everything by feel, without needing to look an or touch my phone: volume, next song, previous song, pause, make a call answer/reject a call, or use Siri (voice commands). This amp, plus the hands-free SoundTek kit, sound great, and cost very little.
Review: Quite Impressive! - I needed a little amplifier for a small stereo stage monitor that I made. I originally purchased the AK-170 class D amplifier off of eBay and I was initially impressed with the volume it put out as it was the first mini class D amplifier I ever purchased. Since that time I have purchased and tried several other small class D amplifiers and they all sounded about the same. I was looking at other small amplifiers on desertcart and thought I would give this one a try. When it arrived I had to do some minor assembly but it went together easy. After assembly, I hooked it up to the same power supply as my AK-170 which is a 12Vdc, 5 Amps supply. To my surprise the sound was night and day. This little baby has some kick. I fed my signal generator into this amp and it truly amplified sound down to 20Hz. It gave me the sound and body that I was looking for. It is definitely a much better quality amp than the others that I tried. Now I have to figure out how to modify my cabinet to accommodate this little guy cause this amp kicked the other one to the curb. I am going to experiment with a larger voltage supply as that will give me even more headroom and cleaner amplification. The blue tooth works perfectly though I think the sound is a little better when using the wired connection. You owe it to yourself to try this little gem. You won't be disappointed!!

## Questions & Answers

**Q: I want to connect dual 120watt speakers. is 24v 5A enough? is 24v 10A too much?**
A: This amp is rated at 100W+100W=200W.  The datasheet says 90% efficiency.  That means you need 9.25A at 24V (200/.09/24V) to generate the power needed for 200W.  A 24V 5A supply can supply 120W, times the 0.9 efficiency, that supply will only give you 108W or 54 W per channel.

**Q: Can I use a 7.5a fuse or will it fry the amp? (I have a classic car with a 7.5a glass fuse with wiring for a radio that I'd like to use.)**
A: The unit takes 12-24 volts DC. The amperage does not matter, you can use a 200a glass fuse if you like :)

**Q: does this come with a power cord / pig tail, so I can wire it into a dc power supply? If not what size plug do I need?**
A: You will need to provide your own power source and it fits a 5.5mm plug.  Above 12V is recommended, and 24V will give you full power.

**Q: Would combining this with a 12V to 24V step up converter when working on an automotive battery improve the sound quality at higher volumes?**
A: Yes.
