Yes. Its Class D TPA3116 amplifier delivers up to 100W RMS — enough for most passive subwoofers. Distortion is very low, so bass stays clean. The NE5532 op amp keeps noise minimal, so your subwoofer hits hard yet remains clear even at high volume. What kind of subwoofer or speakers can I connect? Is it for passive subs only? The NS-21G is made to power passive subwoofers. It won’t work with powered subwoofers (they have their own amp), and since it’s a mono, bass-only amp, it isn’t suitable for full-range speakers. Use it with a passive sub or a bass shaker. How do I connect my audio source? Can I use both RCA and AUX inputs at the same time? You can use either the RCA inputs or the 3.5mm AUX jack to connect your audio source. It works with any device – TV, PC, phone, etc. Do not use RCA and AUX at the same time; connect only one source at a time to avoid signal interference. Is a power supply included, and what power does the unit require? Yes – a 19V DC power adapter is included. The amplifier accepts DC input from 12V to 24V (via a standard DC jack). For optimal performance, use the included 19V supply. If you need a new one, make sure it’s 12–24V DC with at least 3–5A output.
