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.
