Nice and compact amplifier with Bluetooth connect ability It’s hardwired to four Bose shelf speakers and a bass producing wonderful entertainment..

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."

Very useful audio equipment i have 2 subs and 4 speakers hooked to it sounds good for how much amps it pushes.

Exceeded every expectation. MP3, Bluetooth, a remote, 2 speaker sets and subwoofer? I tried every one. Slipped a SD disc in FYI, it goes in bottom side up. Awesome. Pair phone and did bluetooth. Awesome. Cable connected to computer monitor for sound out. Awesome. I am getting ready to try the subwoofer. It even has preset equalizer settings via the remote. Skipped around the SD card using the remote. Way beyond in value from a product priced in the $40's. Wow.

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.
