Review: More than enough for home stereo. - Thunder. For 50 bucks I am blown away by this tiny little amp that kicks out big Power. I hooked this up to a rejuvenated old Panasonic ported subwoofer from a mini home theater system from the '90s that was reloaded with a $30 Skar Audio 6.5 inch subwoofer. The adjustment knob for the bass frequency coupled with the volume knob and the subwoofer/full-range switch on this little Nobsound unit can pump out some big bass from a tiny sub. It's powerful enough that I cannot turn it all the way up and at 50% volume it sounds amazing. The signal is coming from the AUX port of my Fouk Audio mini tube amp. This combination along with some tiny Polk Audio bookshelf speakers sounds incredible in a 12x12 bedroom. Absolute High-Fidelity clarity, rich sound, clear vocals, and thundering bass. This is a great mini system that will sound (and feel) awesome for a medium-sized room.
Review: Incredible sub amp: great way to turn a passive sub into an active sub! - I'm using this with an S.M.S.L. A300 amp to hook up a passive subwoofer to it's line-level sub output. It is working perfectly for my needs. PLENTY of power output (I've got the volume set to about 1/3). This devices cutoff of 300Hz is plenty compatible with the 100Hz of the A300. I did notice that in theory the sub freq knob should be able to go down to about 1/3 without impact, but I notice the difference in sound far before that, so I assume it's a non-linear scale. Not a big deal, but might be nice if the knob was labeled in some way so you knew what frequency you are dialing in. That being said for the price I cannot complain. Note that if you are using this for a sub amp be sure to select SUB rather than PBTL with the second switch. If you select full range (PBTL) it has a drastic impact on the output. Which is a BIT odd since I'm already sending only 0-100Hz to the unit from the SMSL. NBD since the SUB setting is most correct for my use anyway, but something to be aware of if you hook it up and think it sounds... off. Quiet. Dont take my minor criticisms for anything but that: nitpicks. I love the amp and am completely happy, especially for the low price.

## Questions & Answers

**Q: will this power a 50 watt bass shaker?**
A: And by the way..saying "50 watt bass shaker" does not describe or define the bass shaker. 50 watts is merely the recommended peak power. Says NOTHING of how loud it will play, or how good it sounds. Again, power rating DOES NOT DEFINE A PRODUCT.

**Q: Why are there left and right inputs for a mono amp? If you have a mono source, can you plug it into only one input, or do you have to connect to both?**
A: Hello. We have a using guide picture in the listing. You can check that. We have left and right inputs since some customers using stereo signal. If yours are mono, just connect one input.

**Q: When using in sub mode, which rca input to plug in? left or right or both?**
A: Hello. Please see our second main image. The "audio in" rca posts are connected to sound sources. The "spk out" posts are a set of speaker binding posts. When in sub mode, you need to connect your passive subwoofer with bare wire or banana plug. If you still have questions, you can send your device models and images to nobsound@doukaudio.com. We will help you with it.

**Q: When using this with a subwoofer how do I know where to set the frequency cortrol knob?**
A: Like others have said, turn volume up on your main speakers (L/R) to desired listening level then advance frequency crossover knob until you can hear the subwoofer in your favorite music passage, then back the sub down until it is un-noticeable in the passage. Your subwoofer range should take over at the effective L/R low frequency cutoff point...Blend it in seamlessly.

### ⭐⭐⭐⭐⭐ Deep, Hitting Bass. Great for my Computer Setup
*by B***8 on April 2, 2020*

After over 7 months of owning this, I have to write that this is a Great! addition to my setup. I have JBL ten year old full range speakers that I use for the mids and highs. I got these with an old Compaq desktop back in 2002 and still works. The Nobsound G2 Sub Amp is pushing a 250W Dual Voice Coil Subwoofer that I took out of my old Hyundai. Let me tell you this little amp is Loud and provide respectful bass. I believe you can even have a decent party on a 12ft x 12ft dance floor with this set up, larger if enclosed. I usually use this on my laptop while working so it is at a fairly low level, though it can be heard throughout my brick house, bass and all. Let's get to the bass, I listen to Soca, Reggae, Rock, Jazz etc. and the bass is decent in all genres. I suspect some level of equalization is used because for that amount of deep bass, I can't see this small amp producing this. The, what appears to be a low pass filter adjustment can produce bass from punchy to deep and I use this depending on the genre I'm listening to. Punchy for jazz and rock, deeper for reggae, dancehall and reggaeton. I would recommend this amp for rigs such as mine listening as levels such as mine. I'm not going to push this loud for parties, I don't think it would survive long but it does a hell of a job for casual listing. I like that I could listed to music across the room as most computer speakers are "near field" and only sound good when sitting near to the speakers. With my setup, this Nobsound provides good sound for a small price. Get it.
