Everyone is going to want one! I got this to power an old 8” passive sub for my house and it made me a believer. This little thing is amazing. Solidly built with solid bass. It was performing so well I wanted to test my new 8” sub and box I just received for my truck. All I can say is mind blown. This little amp is totally pounding this 600watt RMS sub.I then hooked up a volt meter and I was surprised it was peaking at 28 volts. Did a little math (voltsXvolt)divided by (ohms). I wired my sub for 4ohms. (28X28)/4= 196watts peak power. They. Say it’s a 100watt Max @ 4 ohms but the math show almost 200peak Watts. My guess is that this amp is 100watts rms 200watts peak. I have ran it at this volume for over 3 hours now working on braking in my sub. The amp hasn’t got even warm. Still feels cool to the touch. It’s powered by a 24volt 4.5 amp plug. It doest seem to get hot either. The power supply was only slightly warm when holding it after running it hard for 3 hours.The bass this amp can produce is really amazing. I never thought a 50$ amp can solidly and continuously run this hard and at 4ohms.The 8” house sub is a 3 ohm sub and the amp performed very well. No distortion with clean bass. I have tested it at 2 ohms And got the same results. I found in the book that it says 100watts @ 2ohms but says it’s for 4 and 8 ohm speakers.I’ve had it now for 3 days and have ran it hard for at least 3 hours each day. Haven’t found any issues with this amp. A few of my friends are already asking me where I got it and that they want one. It also has a full rage/sub switch. I have tried the full rang setting also on a 6.5” bookshelf speaker and it was clean and loud. But it will amaze you in sub mode.I would highly recommend this amp to anyone needing to power a passive subwoofer.

I bought this amp specifically to use with a tactile transducer for gaming and it works great. Paired with a Dayton Audio 50 watt shaker and this is thumping. This amp is rated for 100 watts at 2 Ohms, the transducer/shaker I'm using is rated 50 watts but it's a 4 Ohm load. That means that the amp is really only going to put out about 65/70 watts so that reduces the chance of blowing the transducer. If you're planning on using this for a 50 watt transducer just go slow, start at low volume and then work it on up with testing. I only need to set the volume about a quarter of the way up and this thing is thumping. The lower the bass frequency the harder it hits, so you have to watch it a bit. I mounted this to the bottom of my computer desktop right under where my keyboard sits. I have another system, a Buttkicker 2 Gamer under my chair. Playing on the keyboard and mouse in GTA V, when you shot the "assault" rifle you can feel the vibration in your keyboard and mouse hand. For the higher frequency lows like the rifle, it vibrated pretty good, but when the bass get low, it really thumps hard, like when you die in GTA V and that low bass sound plays, it's like 10X the vibration, so just be careful. I'm still trying to find the perfect sweet spot on the amps frequency controls to get the most consistent results, but I'm pretty close and it's very usable, I'm just trying to get the intensity range a little less wide. Amp hasn't gotten even warm nor has the shaker after a couple hours of playing. Also using with SimShaker software for Project Cars 2 and DCS. Between the Buttkicker 2 on my chair and it's amp, and this Dayton shaker and this little amp, I'm getting some awesome results with the combined effect, chair and hands. Amp seems to be built well enough, not quite as cheap Chinesee as I though it would be. It feels nice, dials have nice subtle detents when you turn them and the switches feel good. Can't speak for the sound quality because I'm not driving speakers with voice cones. I'm considering getting another.

I recently added a 10-inch passive outdoor subwoofer to my backyard sound system and needed an amplifier to power it. I wanted one with a physical power switch as I use a smart outlet voice-controlled by Alexa to power on/off both the receiver and subwoofer amp. This did the trick perfectly, and the small size didn't take up much space when organizing everything. I like the controls for subwoofer frequency and volume, and only have the volume know about 1/4 to 1/3 up, otherwise the base is overpowering in my setup. My only complaint about this subwoofer amp is that I get a noticeable subwoofer "thump" when I power it off. I have tried changing the order of which is powered on/off first between the amp and the receiver and adding delays, but the thump is still present. (I read reviews of other units that specifically said they did not do this, but didn't realize this one did or how much of an issue it would be.) I hope I can figure out a solution because my dog kind of goes nuts when he hears it. I knocked off 1 star because of the thump.
