User questions & answers

Question:	Does this amp have enough power to run four 4" speakers
Answer:	This amplifier allows independently customizing the amount of bass and treble from an audio source. It doesn't sound very good but it has those controls.
Question:	I am looking for more control over bass treble. Hook this into any audio out and keep speakers plugged into receiver and still get functionality
Answer:	Mine didn’t come with a power supply either. I contacted amazon to correct the issue. It was a simple mix up since they sell the exact same amp, with and without the power supply. They sent a whole new amp and power supply.
Question:	Where is my powersupply
Answer:	Do you mean white noise? I am going to assume it was a type. If you troubleshoot both inputs as in moving the working channel from L to R and vise versa and both channels work with one wire, do the same from the source. Make sure it is not the source. Try a different device. I mean this is sort of basic troubleshooting. If you find the problem still does not go away , then you have a bad unit and you need to exchange it.
Question:	I'm getting white mouse only when i connect the two input channels. if i only use one, the audio comes out ok from the speakers.anyone know why
Answer:	Hi, please do not worry, the tracker built-in USB Plug.Just pull it down along vertical rather than horizontal direction to separate the device from the wrist strap, easy to charge with any USB block and computer; no charging cable or dock needed

User questions & answers

Question:	Will this amp work with the polk audio psw
Answer:	Yes it will work with the psw505. I have mine running through a Sony SAS9 10" powered sub to my Sony 6 1/2" bookshelf speakers and it sounds awesome. You will need to connect the amp speaker wires to your polk sub 'speaker in' inputs and then wire the 'speaker out' to the speakers you are using.
Question:	Is this 2 x 10watts or 2x
Answer:	Power supply specification is 12 V , 3A. 12V x 3A = 36 Watts. So you are not going to get 20 watts per channel (40 total) even if the amp was 100% efficient, which it isn't.
Question:	Using this am to power 2 external speakers. ok to keep the power on even when the tv is not
Answer:	Yes, it would be fine to leave it on. The power draw would be almost negligible. I have older versions of this amp (with the Tripath chip vs TI), and have had one going 24/7 for the past couple years in my kitchen.
Question:	Is this device intended for cars? I'm confused by the cabinet configuration
Answer:	As a life-long electronics technician and audio amp audiophile from back in the day, I can tell you that since the device is rated at 12 volts, it is indeed compatible for automobile applications. While not necessarily designed or meant for car audio, it will work. If you apply 12V to it as a power source, it will function properly. However, there are a few things to consider: 1. The power output (as you can prove to yourself by examining the pictures and actual specs of the device) is about 30 watts of total output power. (15 watts per channel times two channels - left and right.) This is evidenced by the power specs. The amplifiers require 12V at 3A (which equals 12V*3A= 36W). These are class D amplifiers which simply means that they are very efficient in their power consumption. These class D amplifiers are typically 85% efficient, which means that they will give you 85% of the power out that they consume. 2. Since the power supply (adapter) that powers these amps can provide 12*3=36 Watts of power, your audio output power is then 85% of 36 Watts = 30.6 Watts of output power to your speakers. Again, this IS coming from a 12V supply. 3. As to the reviewers that claim that these amplifiers run hot, I again will refer to the math. Due to the nature of how class D amps work, they don't get very hot. Consider that these class D amps are usually 85% efficient. Since the total supply of input power is 12V * 3A = 36W of power, then that means that the amplifier is only consuming 36W * 15% = about 5 Watts of power at full loudness. Five watts of power does not create very much heat at all. (About the same amount of heat that a little night light produces.) 4. While you can certainly install these lower power class D amps in you car once you route 12V to them, and they will perform well without overheating, remember that you're going to have to mount them somewhere such that they are in arms reach so that the power switch and tone controls are accessible. Also the inputs to these amplifiers are RCA jacks which are very susceptible to the electrical interference that are typical in automobiles. Bottom line: For the price, I love the sound and power output from these amps (I have two of them from Amazon that I use for computer audio and they get nice and loud and have good bass and treble). However, keep in mind that the amps are typically sold either without strong power adapters, or are sold with no adapters at all. Remember the power calculations that input Voltage times Current times the amplifier efficiency = the power output to the speakers. I wouldn't put them in my car (since there are many better installation options available), but for computer or TV speakers/gaming, these amps get good and loud and are impressive, IMO.
