What is the input jack? RCA? 3.5?
Power on/off creates a loud annoying pop. I would like to shut the output with a capacitor to suppress the pop. What capacitor value and voltage?
will this work with an input from a preamp?

Get this instead of an active sub for a piecemeal system, stop fretting over finding an active sub.

With active subs disappearing and becoming ridiculously priced, this IS actually a solution. The passive-to-acitve sub this made, actually sounds better and its quite obvious.Now I do feel that each unit should come with a power supply (cheap to order, but be careful not to get one without!), as well as a 3.5 stereo to single rca... but I assume these exclusions are there to keep the price down, and many of us audiophiles have a bunch of scraps laying around.This is what you want. This is for my piecemeal setup for my pc, and now I can thrift a better active sub!Highest recommendation I can give. Get this, instead of hunting for an active sub unless you need an active sub for a setup that should have an active sub already!PS: Currently using it with a 15v 1a, and it is working great. Full range on this older Samsung HitB mini sub.

Best low-cost sub/shaker amp, minijack input ONLY

Class-D amplifier uses very little power when not used, so it does not need an auto-off switch. Volume knob doubles as power switch, so you can turn it off manually without unplugging it. A benefit of this type of power switch is that it mitigates any power-on/off popping.Works perfectly with an old 8-ohm 8" passive HTIAB subwoofer rated for 100W. I haven't noticed any noise or hissing with this amp, unlike a different (much higher priced) Class-D sub amp I own. I don't think the Nobsound gets to 100W, but the speaker is plenty loud for a medium room. Connected to a passive sub, this Nobsound amp won't shake the seats in your home cinema... but it would if used 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. I have picked up spare ~19V laptop power supplies free from office buildings being renovated, so I have a few options.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 if you plan to drive a bass shaker.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 Fbrand 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.

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

Works very well

I have an old sub-woofer that I rebuilt and the amp plate was not working very well. I was looking to buy another amp plate and saw this product. Given the difference in price I decided to risk it and purchase this amplifier. I was surprised at how good it sounds and how easy it was to hook up. I took out the old amplifier plate and then put connectors with leads to the woofer on a wood plate. I put the this unit on top of the sub box and then connected to the main amplifier sub-woofer connection. I had to put an RCA splitter on the cable and then connected everything via an RCA to mini plug for the input. I used banana plugs for speaker connections to sub-woofer amp. The unit does not come with a power adapter but I had a 12v 6amp power adapter and it worked just fine. So far so good. Sound is clear with plenty of power for a 10 inch driver. I am going to order another one as I have another sub woofer project in the offing and will be using the Nobsound as the amp. I will update if I have any problems.

Good amp for entry level home theater bass shakers, but sketchy seller tactics

Very sneaky... The seller somehow made a bait & switch with their product. I bought this amp (with power supply) for $23.49 on 5/31. It worked well enough that I added another of the same to my cart and sat on it for a while until it had a price drop again ($23.99). This time the product doesn't contain a power supply, and only when you expand the description text does it say at the bottom this specific product doesn't come with a power supply.The original amp with power supply is a good value so far. It's still working after a month of occasional use. I'd give the amp 5 stars for the value at this price, but the shady power supply shenanigans need to be communicated to other potential buyers...

Nice Little Amp, With One Design Issue

The media could not be loaded. I bought one of these and used it to power a bass shaker under my office/gaming chair. It worked well in that capacity for a year, but then stopped working, though the light still came on. EDIT: This turned out to be downstream from the amplifier, and not the amplifier's fault. The amplifier does its job nicely as long as all the wiring is good.However, the unit will generate sparks if the power adapter is plugged to the wall before plugging it into the amplifier! See video. This happens even with the unit turned off. This behavior is apparently by design (there is a blurb in the printed instruction sheet about it), but not what I would have expected. I don't expect there's a huge safety issue with this, but I imagine the issue could be designed away with a different circuit or power jack, so to me that's worth a star.

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!
