Review: Great Home Audio Amp for Speakers & Sub - I bought the Fosi BT30D Pro and it’s a huge upgrade from my old cheap amp. Sound is clean, punchy, and dialogue clarity is noticeably better. Bluetooth works perfectly and RCA input is also solid. The best part is the flexibility — I can connect a passive subwoofer directly using the sub speaker output, or use the pre-out for an active/powered subwoofer in the future. Sub volume and sub frequency controls are very useful for tuning. Overall great value for money and highly recommended for a home speaker + sub setup.
