Customer Reviews
This is great for reviving a broken subwoofer. It saves you from buying a new one, specially if you like the one you have.
Bought a soundbar that came with a passive subwoofer for my desk setup but didn’t have enough stuff to really be effective. Bought this amp, spliced it inline and now have complete low end control at my fingertips. Allows me to fill out the sound quite nicely and it looks good on my desk…
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.
I dont normally leave product reviews. However, I felt compelled to do so. I bought this with low expectations considering the price point. After hooking it up, I was blown away with how powerful this little box is. It runs my 10 inch JL AUDIO subwoofer like a champion. You can't beat the bang for your buck so to speak. Very impressive. 5 stars all day long.
The Nobsound G2 Subwoofer Power Amplifier is fantastic, serving as the ultimate replacement for the Buttkicker Gamer bka-130-c amp by delivering deeper bass, a more compact design, and eliminating annoying auto-off features. This is especially valuable considering Buttkicker charges over $150 plus shipping for an out-of-warranty replacement. Highly recommended!
