Fosi Audio TP-02 Subwoofer Amplifier Home Audio, Mini Bass Amp Mono Subwoofer Amp, with TDA7498E Chip 220W Volume and Frequency Control, for Powered Passive Subwoofers Bass Shakers

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!

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!

I use this with the Fosi MC331 integrated via a 3.5mm plugged cord. It's a simple set up that sounds great in my bedroom system. This little sub amp plays very cleanly with all the heft and detail that Class D amplification provides, especially in the low frequencies. I have the volume set at 1:00 and the crossover frequency set at about 100hz. The input sensitivity is fine for matching the MC331 integrated. There is no phase switch, but switching the speaker wire polarity is the easy work around if needed. I didn't. My small subwoofer now blends so well with the main speakers. It's noticeably quicker than the old $450 Class AB sub amp it replaced. It can play the sub louder to impressive levels, and exceeds my need for power playing even the heaviest music. For those seeking serious bass from larger drivers will be disappointed. "This ain't that." The form factor is good and the unit is attractive... but not as attractive as the MC331 case. I hope Fosi considers putting this same package into the new style case for more design continuity. Still, the combo looks great to me. I'm happily filling my life with more music and Fosi provides a cool, convenient way to have high quality audio reproduction for modest prices. I operate this amp for 8-10 hours per day and it doesn't produce any heat due to the high efficiency and has no perceivable impact on my power bill. This is a great, affordable answer to those needing a modest subwoofer amplifier in a small package. After a long life of having high end audio products, I really appreciate the niche that these products fill. It's an exciting time when quality and attractive audio products are now available to more people than ever. And, listening to music makes us a little less crazy. Rock on and hug your mom.

This paired well with two AuraSound AST-2B-4 Pro Bass Shakers installed to plates under my sectional seats. There is PLENTY of power even with the transducers in series, and the low-frequency cutoff adjustment negates the need for another filter/crossover. My only complaint is that at lower volume-knob settings, the adjustment is *VERY* sensitive. Just a minute amount of rotation to the knob's position results in a larger-than-expected change in volume/effect. A more logarithmic potentiometer is needed.

For how small and cheap this is, its amazing how well it works. Who knows how long it will last but so far we have used these in several projects and they have worked great!

Gave new life to old JBL Music 10 Sub. I have been using an old Sony Stereo Receiver to power the JBL Music 10 and had a Transistor fail and took out the entire stereo. This little Fosi Audio TP-02 Has more kick than the tired old Sony. the sound quality is amazing as well with zero distortion. It was also a great value as other similar replacements are 2 times a much. It also ties into my Harmon Kardon AVR 347 setup and fits perfectly. I would 10/10 Recommend the Fosi Audio TP-02 Sub Amp.

Functions just as advertised the price is pretty good for what you get and it seems to sound and work great with my 10-in subwoofer.

I purchased this to use with a bass shaker on theater chairs. I had a few questions about configuration so I email support. I had two responses within the hour. They answered all of my questions. I am amazed at how well this little amp performed. It will shake you out of the chair. Its so good I am going to purchase one for each chair so each person can adjust their own experience. I highly recommend this product.
