I've been using this amp for 6 months on my PC, first just plugging it into an RCA to 3.5mm audio out, then plugging it to the Fosi K5 Pro (that one's still a story in progress, has some issues but they don't matter to the amp). This amp can very easily and comfortably drive a pair of JBL Control 25AV and JBL Control 1 speakers. No clipping, no distortion, just pure sound with the knob at 50%. For small speakers like that, it is very good. I did not try the Subwoofer output, i actually bought it thinking i'd need a sub with my speaker setup, but both speakers have very nice bass already, and i'm not that much of a bass head so i will be skipping the sub. The BT connection is very nice, although i had to rig my own BT antenna since the one that came with the unit offered too much range. Still, it is always better to have more than to have less, and BT is easy to adapt to a shorter antenna run, so i had no issues with it. The unit definitely gets hot to the touch, but never too hot that it burns me (i can place my hand on the top and feel it is warm), and it is not like it would even get to start a fire if you put something plastic on top of it (i put my Kindle on top of it by accident and left it there for 3 hours and neither the amp nor the Kindle showed any damage). And i got this unit with a very nice 20% discount coupon, so for under $100, this amp is really awesome. Now, for the cons. If you have big-ish speakers, you will definitely need more juice. I tried this amp to a pair of Pioneer CS-503, a pair of speakers rated for 50w @ 8Ω as per the label on the back (and as per Fosi's power table, this amp should be good enough for them on the stock power supply) but are really big beasts, and this amp definitely sounded less powerful on them. Still no major issues, but it sounds like this could use a bigger power supply. On that front, it came stock with a 32V 5 A power supply... and that's a really big mistake, since the voltage range is really small. This unit can only accept up to 36v power supplies, while most other amps from Fosi take up to 48v power supplies. This amp should come stock with the bigger power supply, especially since i doubtr the same 32v 5A power supply could deliver the same quality if i added a sub to it. And to make things worse, the 36v power brick is not even sold by Fosi! They sell 32v and 48v, but no 36v, so unless you get a random power brick, there's no way to juice up this amp. Lastly, having only automatic BT selection can be annoying if you already are listening to the RCA input. It happens to me when i turn on my laptop, it auto latches on the BT and my PC gets silent until i can disconnect it again on my laptop. It is a relatively minor annoyance, but when it happens at least once a day for 6 months, there's no way to even ignore it. Having a BT selection switch/button would be a great help for this. Overall, if you get this amp for under $100, it is a steal for small to mid-size speakers. And the fact that it accepts both RCA and BT inputs makes it extremely versatile. However, there are definitely better options if you need more juice, don't need a subwoofer, or want more control. Fosi makes some other excellent amps, and other brands too, but for $100-110, this amp definitely loses to those other options as other options do deliver better audio quality, are cheaper or can accept a bigger power supply for more oomph.

I bought this after being disappointed with the BT300D (see review). It has good sound and adequate volume for outdoor use but, the pre-out signal is not controlled by the subwoofer volume and cutoff frequency controls. The only way to control the subwoofer characteristics is on the subwoofer itself. This is fine if you have a good subwoofer with volume/frequency controls. I bought a low-end subwoofer from Yamaha that only had a volume control on the subwoofer. The bass was terrible. I put a higher quality Sony subwoofer on it that has the sub volume/frequency controls and bass was much better. This amp also has a larger power supply which really helps with the overall volume of the system and is very clean. It does have a passive subwoofer output which I think may be handled by the sub volume/frequency controls. I'm going to look for a decent passive subwoofer and see what it sounds like. BTW, the pre-out requires a 3.5mm to RCA plug cable.

Plugs right in, just works. The crossover covers a great spread, in the circuit after bass volume control. So you can adjust what sounds good for your speakers, and send the rest to the sub to munch on. The bluetooth doesn't auto-connect, you have to select it, which should be the standard. This replaced a different brand/model that would take over from earbuds, no matter the settings in my phone. We would have to power it off to disconnect. This one works as you'd expect. Great bluetooth range too. Very pleased with this unit, will likely buy more. Only downside- the terminals really aren't built for larger than about 16awg. I got 14awg in, but it wasn't pretty.

Crystal clear sound on the two mids channel, any 2, 4 ohm speaker with around 150 watts output will work great. I using two 4 ohm LG stereo speakers from a system. I am able to get good mid bass from it as these speakers are in box. With this amp I am able to adjust my mid bass and treble to my liking. The amp could also power a Sub exceptional well. I purchase a 6 inch audiopipe sub(Audiopipe TS-CVR6 Subwoofer 6-inch Woofer 150 Watt Max 4 Ohm DVC 1.5” 4-Layer Dual Voice Coil BASV) and a 6 inch box. We wired the sub for 8 ohm resistance. The amp allows volume control of the sub and frequency. It hitting high and lows like a cinema. I set my sub volume to maximum and control the frequency to my liking. As with any integrated system the RCA inputs gives a higher power output. This small amp is very loud and clean. . . Good quality banana jack heighten the appearance. Bluetooth distance is very good and this is a amp I'll recommend for anyone who loves music. Negative is the Amp get really hot but a small USB fan takes it down to room temperature. . . If you leave the amp switch on the the amp remains hot. . . These is minor issues for me.
