Review: The one to buy - I'm more impressed with this one over the larger 36v $36 one of a different brand I was using that cooling fan crapped out. This one sounds better more dynamic and seems to have as much power at 24v also I had to unplug the 3.5mm jack to use the Bluetooth this one you can just link to it even while using the jack as input and it was half the price and no fan to crap out. I'm using for my tv I boxed in the stud cavity's in the wall under my tv and cut in a 6.5" component set and an 8" subwoofer, it's pretty sweet, I also used PVC pipe to install a port into the subwoofer cavity I had to replace the sheetrock with plywood and mud it in like drywall also the sheetrock couldn't support the pressure good even with a wood ring glued on.
Review: Not bad for a cheap sound system. - I'm actually surprised that this works as well as it does. I hooked it up to the speakers in an old Samsung TV soundbar and subwoofer. I usually connect via Bluetooth from my laptop. It sounds much better than anything this cheap has a right to sound. Everything functions, the Bluetooth is reliable. I can't figure out if this is the amp, but I have to keep turning down the subwoofer, probably because the speaker I hooked it up to is cheap. Otherwise, it's loud and clear.

### ⭐⭐⭐⭐⭐ Exceeded expectations
*by A***R on September 29, 2025*

I have a couple of these. Bluetooth sounds better than using the cord. Use an appropriately powerful DC laptop brick or anything similar if you want the biggest sound. The one connected to my PC uses a 200w 20v DC brick to drive 4 speakers (2L and 2R in parallel) plus 2x 12in subs (also in parallel). It will shake things off the walls in my house. You won't believe the performance from such a cheap device. Pros: Easy to assemble, wire, and connect power. Bluetooth setup is simple. With the right power and speakers/sub, your neighbors will think there's an earthquake. Cons: Slight hiss if you leave the main volume knob turned up to max with nothing playing. If you're listening to something with pauses at low volume, it may not play the next spoken syllable or noise. This does not happen at medium volume or if the movie you are watching has birds chirping etc in the background. It's almost as if it goes to sleep for a fraction of a second.
