S220HS

Powered off of my 24v lifepo4 battery in my semi truck. Pushes the highs at 2ohm and a kicker comp 10 150w rms 4ohm real nice. Sub is in passenger floor in front of seat, can feel and hear the bass very nicely. I will probably upgrade to the metal encased version in due time, but works good for me.

Worked great till I upgraded my amp

This is a very clean-sounding, capable amplifier. I'm impressed with the amount of power it can handle, and all the features that come with it for about one-third to one-half the cost of a commercially available amp with similar features. It's goo, but there are some things that are not included that would make it great. Pros * Good, clean power. Very low noise, unless you introduce it yourself from a ground loop or similar power issue. * Takes a wide-range of input power. I started using a Lenovo laptop 19v 5 amp, and then bought a new 36v 5 amp. For my setup, there was practically no difference. * Separate controls/output for subwoofers. This jacks the price in the commercial options to the $150+ category. * Lots of input options, although I think most will use the 3.5 mm audio cable or Bluetooth. * Customizable - if you have a 3D printer, you can make it look like anything you want. Cons * Big "pop" sounds when you turn it on or off. No power on/power off protection/relay to overcome the big capacitor discharges. You can fix this with a $13 board off Amazon (https://www.amazon.com/dp/B0DP9CLBMF?ref=ppx_yo2ov_dt_b_fed_asin_title), but it's an extra cost with extra skill most might not want to take on to play their music. * No high-def audio codecs with Bluetooth. The app is pretty cool, though, if you want a custom name for your Bluetooth connection. I'm using it to drive my home entertainment center, from TV to DVD to PC and streaming music and just love it.

I am totally blown away that something so small can put out so much sound. I have purchased several of these in various sizes for my projects. In my experience with amps i have never seen anything like these. They can plug into accessory plugs in car and the supply cord don't even get warm. Amazing. Anything compatible so far would have to have a supply wire the size of little finger and still get hot. Easy to install and top value for the money. Get a handful of them, you'll find a use for them. They can fit in multiple places because of the compact size and light weight. Controls are easily accessible and sub control is convenient.

This little amp can put out some good sound. I used this with my old Bose cube speakers, got 4 of them hooked up and a subwoofer.. for the price and sound it’s totally worth it. Wish it was 5+1 though, that would be awesome. But it works well for the price! I can’t find an app for this unfortunately.. I thought there was one, but I searched everywhere and found nothing. Oh well

Súper potente y de buena calidad, poca distorsión en el audio, lo recomiendo

I didn’t check this out quickly enough to exchange this defective item for another. The power switch doesn’t work. The unit stays on so it is functional. Also the dials are not properly aligned. The sound is pretty good and the unit is powerful enough to run 2 sets of speaker and a 12 in subwoofer. Would be 4 stars if the power switch worked and 5 if the dials were aligned properly as well.

Gave it 5 months of use before doing a review. Powering a Skar EVL6.5 and a pair of Polk 3.5 all with home brew boxes. Bluetooth has never had problem. Power is good. Sound quality is good. Volume/level controls are not super linear, but work. It's fan can be a bit loud, as loud as my laptop fans at idle and the top plate vibrates sometime. Haven't put much thought into a good remedy, should be an easy fix, maybe orings..

You can see that it was pulled out of something and there was one screw missing and it was all loose and the smell is also not what it should be. The Master Vol potentiometer also does not work as it should. It does not always want to turn on the first time
