  • Using for seat transducer and it's great
Wired up 3 seat transducers and it works great. Delivers a great amount of power.

  • Best low-cost sub/shaker amp, minijack input ONLY
Works well with an old 8ohm 8" passive subwoofer. I don't think it gets to 100W, but the speaker is plenty loud for a medium room. I haven't noticed any hissing with that configuration. Connected to my passive sub, this amp doesn't exactly shake the seats down in my sister's home cinema. But it would if I used it as a bass shaker amp. This amp pairs nicely with a 65W/19v laptop power supply and a 50W BST-1 bass shaker. I love how my lounge chair rumbles while watching The Dark Knight, especially when the Batmobile is on screen. I've also hooked it up to four 16ohm 25 watt bass shakers and an old 135W laptop power supply to make my computer chair shake with movies and games alike. (Those small shakers rattle during the lowest frequencies, but that's a different review.) This amp has a decent low pass filter, especially for the price, but it will pass the lower voice frequencies to bass shakers if fed a full signal. I recommend a 70Hz low pass filter, or use an LFE port set to 80Hz. The only real negative is it only has a 3.5mm minijack input. I did a head-to-head comparison between this amp and a PBTL/Sub amp from a big brand on Amazon. That PBTL/Sub amp did NOT work well at filtering voice frequencies, no matter how I turned the knob. I ended up returning that one and keeping this Nobsound amp. The Nobsound doesn't have a ton of features, but it just works. ... show more

  • Well designed and compact
Works really well for what it is and was perfect for a budget build. Only downside is there’s no low pass filter which means you get voice from your sub. Not a deal breaker by any means. Still moves the sub like mad. Don’t forget the power supply

  • Powerful.
I'm using this to power a 18 inch Rockville subwoofer and it rocks it it has more then enough powerI don't even turn it up half way and it vibrates the floor I love it.

  • Not Bad...
It is pretty great for the price point. The only real problem I have with it is that it doesn't have an on/off switch. But this can be easily remedied by using an extension cord that has an inline switch. Other than that, this is really good. I was worried it wouldn't be powerful enough to run my giant subwoofer, but it does. Maybe not as powerful as a full powered speaker, but it has a lot of thump to it. It doesn't have quite as much power as when I was able to run the subwoofer off the receiver directly, but that's a good thing. It was a bit too boomy before. Now, it's just about right. The BIGGEST problem is every so often, the subwoofer will just put out a HUGE and constant booming buzz or hum. I have solved this by unplugging the power cord and plugging it back in. But the noise came back. I unplugged the plug part of the cord and turned it around before I plugged it back in. This fixed the noise...for a while. But last night, I noticed that when the noise happened, I picked the amp up to turn it off...and the noise stopped. I realized that I had jiggled the 3.5mm input connection. I've tried everything that I can think of to get the noise to permanently stop. It should NOT be this difficult to get this thing to work. If I had known the trouble it would give me, I would never have wasted so much money on it. ... show more

  • DOES NOT HAVE A POWER SUPPLY/CABLE
The unit functions well. It can power a large subwoofer. I have it running a 12" Kicker CVR automotive subwoofer (1,200 watts RMS).

  • Buy the one with the power cord
First off, save yourself some money and buy the other model that comes with the power supply instead of buying them separately. Now for my impressions: No auto power off - this sucks I bought this to use on a passive sub. It works adequately for the situation but don't expect earth shattering bass. My sub provides subtle support to the sound stage, which is good, but it doesn't have a ton of volume even with the knob all the way up. If I had it to do over again, I would just buy the Monoprice powered sub. This solution is too much of a compromise in order to save $15 in my opinion. ... show more

  • Works fine with adequate power supply.
Desceptively small but gets the job done...if you get a nice DC power supply. for $18 I got a 24volt x 6 amp supply with the right connector (center positive, 5.2mm). Goes right up to 100 watts with power to spare. When I used lower power bricks the amp peaked about half way up the dial and then dropped off, as others have reported. Nothing wrong with the amp. It's the wimpy power brick! ... show more
