Which type of speakers works best with the TP-02 Amplifier?

TP-02 works well with most 2-8Ω subwoofers.

Why does the TP-02 make serious noise when used together with a radio?

The common feature of Class D power amplifiers is that they can cause serious noise when used with a radio, so we do not recommend using the TP-02 with a radio or too close to it.

Why does the amplifier stop working after a period? And after a while it work again?

The amplifier is in this case normally overheat protected, and the output power may have exceeded the designed range, so you can lower the volume a little and try again.

Why isn't the powered subwoofer working?

Connection: Computer (3.5mm Headphone Out) → TP-02 (Sub Out) → Powered Subwoofer. If the powered subwoofer has an LFE port, use a mono RCA cable.

Fosi Audio TP-02 Subwoofer Amplifier and Dayton BST-1 Bass Shaker

This amp was purchased to power a Dayton BST-1 Bass shaker. It does it with out a sweat. It is used on a sim racing cockpit under the pedals. It never goes over half as the rig would just vibrate to much. Perfect when using Simvibe software on PC, clean sound and very powerful. I have just got another to go under the seat, so two amps, 2 Dayton 50watt BST-1 bass shakers. Perfect combination. Would easily recommend for Bass shakers. Cannot verify for music as not tested, used for that.
