    • Good and cheap
Style: 4.1 Channel
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. ... show more

    • A decent little budget amp!
Style: 4.1 Channel
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." ... show more

    • This is perfect!
Style: 4.1 Channel
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. ... show more

    • Not stereo
Style: 4.1 Channel
NOT STEREO- not 4.1 channel, it's mono & not even remotely close to the wattage described, this thing shuts down if you turn it up even 1/2 way. Look I know it's cheap but this is a flat out lie - far FAR better off getting a $25 200w car stereo, which is actually stereo & is at least 2x as loud. How do I know? Because I did exactly that and it's so much better. POS ... show more

    • Unbelievable Capabilities. Amazing!
Style: 4.1 Channel
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. ... show more

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