## Questions & Answers

**Q: Is this 12v car battery compatible**
A: Yes it’s what I do with it however you won’t get 100w at 12v

**Q: What sort of subwoofer output is this + and -? Just two naked wires to connect to a passive subwoofer?**
A: Although I am not using this it is a single speaker output to a 4 ohm subwoofer.

**Q: Question for manufacturer: Does this take a stereo input to create mono output from the combined sources or do I need to feed it a mono source?**
A: Hi, I used this to turn a passive subwoofer into an active one for my A/v receiver, taking a mono cable to the sub out on the receiver, I then connected the twin speaker cables to the two audio out on the mini amp

**Q: HI. Does the amp contain a crossover or filter - so that full range sound can be applied to the inputs but only bass sound is passed through the amp ?**
A: Yes, that’s exactly what it does. I feed it directly from the headset output from my laptop, and have it hooked up to a normal speaker which due to the output from the amp only being the bass frequencies now works as a sub. Works surprisingly well tbh.

### ⭐⭐⭐⭐⭐ Great little subwoofer amplifier
*by C***N on 3 February 2025*

Great little subwoofer amplifier. I have it connected from a soundbar and drives an old surround sound system subwoofer. It really does sound great, and packs a punch to tv audio! One point is that it doesn’t work with a stereo jack, only works with mono jack!
