Review: Works really good along with my old Kenwood receiver. The addition of a subwoofer makes my old sound systems shine!!!! Now it is 2.1 system! This little amp is compact and enough to drive my 6" passive subwoofer. I just have it cranked halfway and is more than enough to bring those sub-frequencies up to par with the music. Enjoying my music with a new perspective thanks to this little guy. When you get it, don't forget to put the switch in bass mode. Recommended unit!!!!
Review: Tenía un equipo de sonido Onkyo con subwoofer pasivo, hace poco lo reemplacé por uno nuevo que sólo tiene salida para subwoofer activo, mi subwoofer anterior aún servía, así que decidí comprar este adaptador y funcionó a la perfección.

## Features

- G4 can be used as full frequency amp or subwoofer amp with the B/M switch to connect different speakers, and with 3.5mm AUX and RCA input to compatible with different audio devices. 2PCS G4 can be used to drive left and right channel independently to avoid mutual interference.
- Adopting 2PCS NE5532 op-amp and TI's TPA3116 chip, output power up to 100W enough to drive passive 3-10 inch full-frequency speakers or 4-12 inch subwoofers, no audible noise even at large power output, upgrade your 2.0 channel audio system to 2.1, providing shocking cinema effects.
- By combining the stereo(left and right channel) input, first to do signal analysis and frequency processing and then power amplification, the low-frequency filtering will be more pure and power consumption is more efficient.
- Mini size with exquisite appearance: mono integrated class D amplifier, simple compact design but with powerful function, more fashionable and durable solid aluminum chassis, very suitable for HiFi home and desktop audio system use.
- Notice: this is mono amplifier, if you want stereo output please buy 2PCS or 3PCS.

## Questions & Answers

**Q: Can anybody tell me definitively--no guessing please--that the aux input is stereo? Is it only inputting one channel (left or right), or summing them?**
A: The system is just giving you a mono signal the subwoofer output on your receiver is just a mono signal unless you have a right and left output. I have never heard of right and left output before for a subwoofer, but I guess there is always a possibility.

**Q: Is this a good choice for a center channel speaker?**
A: It may work for you, depending on your speaker, the amp on other speakers, the other speakers, your set up (assuming you have something to feed a distinct center channel) and your room.  I wouldn't.  How many volume controls do you want to get up and mess with?  If you're trying for a home theater setup, you'll be happier with Amazon's entry level Onkyo 5.2 system at $329.  Use the speakers you have and upgrade as you can afford.  On the other hand if this is a dorm room, go for it.

**Q: I have a powered subwoofer but need to combine left and right channels with a cross. will this conflict with my powered sub?**
A: probably not a good fit with a powered sub unless you are replacing the amp in that sub.

**Q: can it handle a 12 inch sub 200watts?**
A: It can drive the speaker, but how well will depend on the efficiency of the speaker and not just the size and watts it can handle.

*by A***R on 24 October 2022*

I two of these have this paired with topping E30 dac, L30 headphone/pre-amp and a pair of old Kef 60S on my desk, one per channel obviously. Much stronger bass / mid-range and improved sound stage compared to my old little class d amp (75W). Separation is improved and crosstalk is pretty much eliminated with this set-up. Definitely Hi Value Hi Fi!
