4.1 Channel Home Audio Amplifier Receiver, Bluetooth 5.0 Mini Amp with Subwoofer Output, RMS 4x50W MAX 800W for Home Theater/Car- USB/SD/AUX Input, for Passive Speakers and Active subwoofer

I heard two sets of 6 1/2 component set sitting around the house for a car that was total so I had a wild hair of building this around town out of those component set and they worked out not perfectly but OK but this little amp pushes them very well. The remote is very small so it is easy to lose, but it is very user-friendly. Volume only goes up to 30 or so, but it is loud enough.

Compact and easy to hide. Sound quality is good and connects to all my Bluetooth accessories when needed.

I wired this in to replace a 20 year old amp that spent some time suffering in a hot attic. The sound before was muffled and sometimes difficult to understand speech. I don't honestly know if that old amp always sucked or if the capacitors degraded from poor storage. Either way, this new amp is working MUCH better. Sound is reasonably clear. And I'm not enough of an audiophile to blame even what I'm noticing on the amp versus the speakers that were shipped with another amp, so that's not even fair to judge. (Basically, they're probably cheap and crappy speakers, so not fair to judge the amp on those alone, but they're sounding reasonable and I'm fine with it.) The only thing I've noticed is from doing a left/right stereo test, it seems this amp only operates monaural, even though it drives up to 4 speakers. I do have 4 speakers, but was only going for "stereo" audio, but seems like this amp doesn't differentiate. It's better than the lackluster amp I had before, but I did kinda want stereo, but that wasn't hugely important. I'm using it with "line" input, I haven't tested Bluetooth to see if that's also the case, nor is it practical to my application. In any case, if you just want a reasonable personal use amp, this one's "fine."

I had this as a replacement idea because another one (pyle marine BT one) ended up not working at all. This one is great! Good bass and the Bluetooth is really cool! Ultimately I realized I wanted to add a mixer for a few karaoke microphones and added a separate Bluetooth transmitter in the mix too. So now I have 3 microphones and a tablet input through the mixer to the transmitter, received to this unit which pushes 2 channel stereo to a pair of great 5way 6x9s and a 12 inch sub. It fills the party bus perfectly. No window shaking, no cracking or hissing.

Get it!!!! Omg it brought my grandpa's old JBLs to LIFE! Receivers cost to much and wont hold this power! This is a game changer! Bluetooth too!!! I run my music and movies through this! Its smaller than a book and has block party sound!

This unit works well and powers 4 Polk atrium 5 speakers well. But when I turn it on it always defaults to line input. I have to switch it to BT every time and it makes very loud beeps when switching. I may replace this unit for that reason.

Sound quality is ok as long as you don’t turn it up too loud. Crazy LOUD when pairing to a device though.

This is a really good little amplifier that I used for four powerful outdoor speakers at my pool. It’s installed in my outdoor kitchen inside the cabinet. The Bluetooth still works great has a more than reasonable range in the output is surprisingly good. This is it great product for the money.
