My ButtKicker amplifier kept blowing and I simply could not afford to buy yet another amp. I decided to try the Nobsound G2 as it is so affordable, and it has been fantastic. I don't race much on my PC, but the past 5 months the Nobsound G2 has performed faultlessly in powering my Buttkicker Gamer 2.

Needed this for the new surround receivers that no longer provide for passive subs, even when they say they do! It works perfectly and being able to tune the frequency is excellent for setting up great low frequency sound.

サブウーハーとの併用でButtkickerの重低音振動ユニットを以前から使用しており、振動ユニットのみ単体のサブウーファー用アンプで駆動していましたが、元ソースとして使用しているAVアンプのLFE（※低音域効果音チャンネル・通常はアクティブサブウーファーの駆動用に使用）ライン出力が低いのか、ある映像ソースでは丁度いいのに別のソースでは目一杯ボリュームを上げても殆ど反応しなかったりと今ひとつ安定せず、かといってAVアンプのLFEを弄ると今度は全体的な音のバランスが崩れるという、どうにも決まらない状況でした。こちらのサブウーファーアンプも基本仕様は元々使用していたものと殆ど一緒でしたが、入力ソース側のゲイン調節が可能という点に惹かれて購入。デフォルトより１段低い入力ゲインで設定したところ、従来のサブウーファーアンプでは殆ど反応しなかった映像ソースで振動ユニットが反応し、元々が丁度よい映像ソースでも音量ボリュームの可変範囲で調整可能と、まさに狙い通りの効果で上々の使い勝手です。

Awesome!! Best little bass amp on the market. Paired this with 2 Dayton audio TT25’s for a drum throne for use with electronic drums. For the price of TT25’s and the bass amp, it sure gives my buttkicker a run for the money. Considering the buttkicker comes in at almost 4 times the price. Now I wish I went this route for my racing sim rig. This little unit will definitely power some BST-1’s. Try it out, you definitely will not be disappointed

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.

Amplificador clase D de buena calidad; sin embargo para sacar el mayor provecho se requiere de una fuente de mayor voltaje y a corriente para aprovechar la máxima potencia, cumple cabalmente, el nivel de audio es aceptable si se poseen los woofers adecuados, buena compra.

Bought this to pair with a Buttkicker Concert Mini mounted to my drum throne to provide sub bass feedback when playing electronic drums. Switched it to Subwoofer mode, dialed the crossover frequency right down and it works perfectly!

I needed something inexpensive to drive an old non-powered sub-woofer I'd gotten from a friend. The price was right on this so I took a chance.For such a small little device, it sure packs some punch. It's doing the job I need it for perfectly, and has thus far better quality and power than I was expecting. I'm no audiophile, but this thing is worth the money; of that I'm sure.For those experiencing buzzing, make sure you power this from the same electrical source as the rest of your system (same power bar). The one I have is silent when there's no signal.

Cheap, good sound and really fast delivery!I bought a cheap 450W powered sub on eBay but it didn't work. Scouring the net I found this amp and decided the outlay was worth risking on an unproven speaker. I ditched the old amp (but salvaged the banana plug terminals and internal wiring) and hooked up this new amp—needless to say, it surpassed my expectations.TBH, I've noticed the tiniest bit of a hum from it, but I previously had huge issues with a ground loop that made my previous set-up un-listenable. Once I've got music or a movie going, the hum is not at all noticable, even on quiet stuff.From what I've seen, there aren't many other mono amps at this price with a frequency dial. And there's even fewer with a bridged mode (PBTL), not that I need this functionality myself. My only wish is that the frequency dial doesn't have any measurements on it, so I've had to guess where the 80Hz mark is.Finally, mine was delivered next day. Very impressed!
