It accepts Bluetooth and RCA sources, offers a switchable PBTL\/full-frequency or dedicated SUB mode, and includes bass gain control to tune low-end response. The M01-BT is intended for passive subwoofers, passive speakers in mono, or for integrating with an active subwoofer via RCA—note it is not suitable for active (self-powered) speakers as the main speaker output.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the M01-BT add Bluetooth to a subwoofer setup?\u003c\/h3\u003e\n\u003cp\u003eBluetooth 5.0 on the M01-BT lets you stream audio from phones, tablets, or computers without extra adapters.

The Fosi Audio M01-BT suits users who want a compact, efficient amplifier to add serious bass to a small home theater, gaming rig, or DIY audio project without a bulky receiver. It's ideal for owners of passive subwoofers or those who need a single-channel, high-power mono amp for a bass shaker or dedicated low-frequency speaker. If you have only active speakers (self-powered), consider a different solution—the M01-BT is designed to drive passive loads or feed powered subs via RCA.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can the M01-BT drive active (powered) speakers?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. The M01-BT is designed for passive subwoofers and passive speakers; use RCA to feed a powered subwoofer instead.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the amp support Bluetooth streaming?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
