Title

The Fosi Audio BT20A MAX is a 2.1-channel Bluetooth 6.0 HiFi Class D amplifier with PFFB, rated 300W x2. This listing is the 48V power supply version.

The 2.1 layout means you can run a stereo pair plus a subwoofer from one box, which is exactly what most desktop and small-room systems actually need. Bluetooth 6.0 covers phone and laptop sources without extra hardware, while wired inputs handle your main source. If you're building a bookshelf system from scratch, this is the amplifier that lets you skip a separate sub amp.

Frequently asked questions

Is this unit genuine?

Yes. TonePier is an authorized retailer — every unit comes from the brand or its official distributor, carries a valid serial number and is covered by the full manufacturer warranty.

How long does shipping take?

SKUs stocked in our US warehouse ship within 1–2 business days. Items shipped direct from our China hub typically arrive in 8–15 days with full tracking. The product page tells you which applies before you order.

What if it isn't for me?

You get 45 days to decide. Keep the packaging, keep it in like-new condition, and send it back for a refund. Ear tips unsealed for hygiene reasons are fine — we expect you to actually listen.
