Review: Great amp! Great value! - Bought the TP-02 to replace a dead Klipsch SPL-120 subwoofer plate amp that went bad. This amp was easy to hook up after I added passive input to the speaker cabinet. Wow! This amp really provides plenty of power for the speaker and the crossover works perfectly. Very pleased with the sound and it saved me from an expensive repair or replacement sub. Great value!
Review: An excellent, cost-effective product - I have a 7 year-old Polk PSW110 subwoofer. Recently, its plate amp failed. The amp, while easy to replace, hasn't been available for quite some time. I found one on eBay, untested with no returns, so I passed on it. I couldn't find one on Facebook Marketplace. I called the U.S. repair facilities listed on the Polk audio web site. They would all repair the plate amp, but the least expensive facility quoted $100 to evaluate (applied to the repair), plus parts, labor, and shipping, with an estimated total cost around $200. I can buy a new, fairly equivalent 10-inch subwoofer for $230, so going the repair route was not cost effective for me. Then I decided to "think outside the box". What if I got an external amp, I wondered. I did some searching, and came across the Fosi Audio TP-02, which costs only $70, so I figured I'd give it a try. I was able to bypass the Polk's plate amp quickly and easily, thereby converting it from an active to a passive subwoofer. I'm happy to report that the TP-02 is well made, compact, easy to connect, and easy to adjust. Most importantly, I am very pleased with its performance. It provides deep, clean, extended bass response, with extremely low distortion. It can put out way more power than I need in my moderately-sized listening room. Thanks to the TP-02's low idle power consumption, I leave it turned on all the time. When my receiver is turned off, if I put my ear right next to the subwoofer, I cannot hear even the slightest amount of hiss, hum, or buzz. I consider myself to be an audiophile, and I enjoy listening to many genres of music. If you're looking for an excellent, cost-effective way to bring a powered sub back to life after its amp bites the dust, the TP-02 subwoofer amp is the way to go.

## Questions & Answers

**Q: Which type of speakers works best with the TP-02 Amplifier?**
A: TP-02 works well with most 2-8Ω subwoofers.

**Q: Why does the TP-02 make serious noise when used together with a radio?**
A: 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.

**Q: Why does the amplifier stop working after a period? And after a while it work again?**
A: 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.

**Q: Why isn't the powered subwoofer working?**
A: 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.

### ⭐⭐⭐⭐⭐ amazing mini amp so worth the price!
*by E***T on December 30, 2025*

Amazing mini amp right here, works great on small subs that can take more wattage, this sub in the video is a 600w 8” boss audio sub, also bought here on Amazon, but the mini amp is really able to push good power to the sub even at low sub volume and frequency, and makes good sounding bass, no rattling or anything, just good clean, deep bass. I would 100% recommend for anyone interested in starting a room audio setup or home theater!
