Good, cheap, low power amp.

Running this off of a rechargeable battery pack to add sound to a Ghostbusters costume.  It won't rattle the windows, but it's small and light and gets the job done.  It works well for my purposes, but being a pretty unorthodox use for the amp, I can't really speak to it's audio quality.

I got this compact little amplifier to run a pair of bookshelf speakers in my kitchen from my computer in another room.  I got a headphone splitter for the computer to run the powered speakers in my office as well as the Pyle unit.  When I received the unit, I was impressed with its small size - it's about 6" side and 3" tall.  I got it all plugged in and it works just as I would expect it to - with pretty impressive volume, and I like the adjustable bass and treble.  Granted it's powering little bookshelf speakers, so a lot of power is unnecessary so I can think while I'm cooking.  Inexpensive and a reliable choice.

Decent amp. It's overheated once running the channels at 4 ohm. I do live in Phoenix though. I really don't think it does rated but then again my volts are not up to 14.4 volts

While helping out with a local haunted house attraction, I got frustrated at the huge, bulky home stereo amplifiers we were using to play CD sounds. I found these inexpensive PYLE amps on Amazon and ordered one to try it out. The 40 watt was not quite loud enough so I ordered a 75 watt the next week.

For an inexpensive amp, it worked great! Tiny, small, and simple. I would like to see all of our old amplifiers replaced with these things. Hard to beat for the price Amazon has them for! And the sound quality was just fine (and, using two Pyle outdoor speakers to test in a home environment, louder than one could use without disturbing the neighbors).

I now own three Pyle amplifiers.

Low cost, with adequate power, and very easy to hook up. Installed into 2010 base impala (LS trim) with stock radio system using speaker level input into amp; allows stock head with no RCA and conveniently allows power on/off of amp with no accessory hook-up needed .  Used with single polk 10" dvi1040 in a vented box (49.00 sale package from Best Buy).  Ran power using true belden 8 AWG wire (purchased a chinese wiring kit, and only used the fuse holder with MY real wire).  Mounted amp to sub box for now (till summer).  I am getting much, much better base response.  I do need to "open up" rear deck as the solid, fixed, rear foam seat does muffle some woofer sound, and I also need to place speaker baffles behind/beneath the stock 6 X 9 stock speakers in rear deck for their isolation (again, next summer when it warms up).  Sub currently positioned behind, and touching, back of rear seat and angled 45 degrees facing side/rear for best sound so far.  So with this system, you get much, much better sound for less than 200 dollars total, AND you don't have issues with straining your alternator/battery staying with a moderate solution like this.  And, as I am driving a 4 ohm load, I'm utilizing only 300 watts RMS max from amp, so it doesn't run warm with this limit.  The rated 270 watt RMS speaker is about perfectly matched.  Bottom line, very happy.

Good sized practice amp or for a small venue. Small, easy to transport and works well with both my 6 string and my twelve string, having a good response, fairly flat output over the range of the guitar. After all, it is a Marshall. By now, they know what they are doing. Also, if you are using one the Dean Markley sound hole pickups, the overdrive channel can still give a pretty darned good, uncolored output without the need for an in-line preamplifier. It also works well with a mic for a small PA amp as well.

Now that I've been using this amp for awhile, I would like to add some comments on my experiences with it, which frankly are quite good. The first item is that I live in a three story condominium complex. To avoid annoying my neighbors I either have to use it with headphones, which means that I have to use a 1/4" to 3.5mm adapter for the headphone jack, or use the amp at low volume levels. Remember that most amps carry a lot further than you think so easy on the volume or incur the wrath of your neighbors!

I have twice played for small gigs and have found out that this amp is good for about a 30ft maximum throw with adequate sound levels. I wish that I'd gotten the model with the reverb, but even so this is a good amp for the price and the 15W RMS is more than adequate for most practice or small venue applications. Even with the overdrive channel in operation, you can prevent having the neighbors come for you with pitchforks and torches as the amount of distortion is separately controlled by the overdrive channel's gain and volume controls to prevent disturbing the neighbors.

All in all I am very satisfied with this amp for use with both mic'd Irish whistles, harmonicas and electric guitars. However, it is a bit thin when it comes to being a good amp for a bass guitar due to its speaker size.

Very good amp for the prices,  the only problem is it gets hot (because no built in fan) and will go into protection mode...have it  pushing 2 12's...gives good bass quality for the price....if your on a budget looking for a good decent amplifier this is a good amplifier....

At a low price, this is a decent little amplifier. It works well overall and it has a simple design.

If you want anything over a mild volume, however, the amp will overload/cut out and that of course, is not enjoyable in the middle of a song. I would not buy this product again, however for low volume listening it works okay.

This is a pretty decent amp for the 40 bucks. My girl blew it out a few days ago, but until that point, this drove my two tens in my jeep pretty good. Good amp all around, never overheated on me, and id run it for hours on end. For a cheap amp, this out-performs.

This amp works well for practice. It is loud for what it is and I like the belt clip it comes with. Big sound out of such a tiny package. Works on a 9v battery, get a power supply it goes through batteries.

Got this to replace a Sony powered sub-woofer that died, and I needed a line-level (47K input impedance) input. At least at my volume levels, no problem with an under powered power supply. Mine came with a 12V 3A supply, so could expect around 36W available to the amplifier, making the 40W (2 20W channels) output almost believable.

decent little amp for the price.  Nothing fancy, just a good practice amp.

As someone just getting in to setting up their own stereo components, I found this to be a very effective starter amp. It provides a decent amount of power and the control are simple and effective. For under twenty dollars I don't know how you could possibly get a better amp.

This amplifier puts out nice sound for it's size.  I'm using it to power outdoor patio speakers and it works great.  This amp did not come with a power supply, this was not in the description.  Be prepared to spend another $10 +/- on a power supply. Also be sure to get the correct power supply, the wrong one will effect the performance.

I've got to admit that this is a pretty cool little amp. I've used it to power bookshelf speakers as well as two 15" Polk audio subwoofers. This thing has surprisingly clear sound and the option to run as a full range / bass amp is pretty cool if you asked me. The price is right, though,  you get what you pay for. For 50$+ some odd dollars, don't expect ground breaking bass or crazy loud mids/highs. I had a lot of fun tinkering and experimenting with this amp. If you're not looking for big sound and want cool casual listening, this is the amp for you.

Very good amp for the price, puts out over rated power at 14.5volts, i have it running off a single 15inch SoundQubed HDC4 at 0.5ohms, it pushes it pretty good, but not the best due to the subs high power requirement, but any other cheap mid to low end sub it will push it very well, keep in mind the amps internal circuitry isn't the highest of quality, i don't recommend running it on a 0.5ohm load unless you have a very strong electrical system.

Great little amp. I use it and a 5-disc CD changer to drive a pair of Pioneer HPM-100 speakers. Unfortunately, this amp does not have any kind of a mute or low-volume option, so turning the volume up past 3 or 4 quickly becomes very loud. I have also attached an iPad, iPhone, and even an iPod Shuffle to the amp with great results. No problems after over a year of use.
