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!

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!

I'm coming from a failed Dayton SA100 so this made for a timely replacement. I'm powering a pair of Aura Pro AST-2B-4 in parallel, which comes out to 8 OHMs with up to roughly 100 watts It does what it says, it can drive a subwoofer (or tactile transducer) within 2 - 8 ohms, but at about 100 watts, 200 PEAK. It comes with an 108 watt brick, no additional cables This is a D class amplifier, so with that comes the benefits of being compact and generally very power efficient over AB amps. However from an high-end user perspective, I did lose a bit of fidelity. Nothing major, being that I am using transducers mounted to my seat I don't need that level of precision. That being said, the potentiometers leave much to be desired. Both knobs have a bit of play to them and are touchy still, so if you're the type who likes to adjust their settings according to the situation you may want to keep this in mind. In fact I'd look to spend a little more for this fact alone. Otherwise the included 108 watt power brick does the job, however I'd splurge for a 200 watt brick if you're running more than one sub/transducer.

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.

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.

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.

This thing packs a lot of punch for it's size! I have it powering a Skar Audio IX-8 D4 8" subwoofer in a slot ported enclosure as the low end for my computer sound system. This amp puts out way more power than the IX-8 needs, so I've only got the volume on this critter turned up about 25% and it sounds great. I like it so much that when a friend's powered home theater subwoofer's plate amp failed, I recommended this as an alternative to replacing the sub. He purchased it and is also very happy with it's performance and value. My desktop sound system consists of this amp for my sub, a Fosi Audio tube pre-amp, and a Fosi Audio 2x50 watt amp for the mains. The sound that comes out of this setup is nothing short of amazing! I highly recommend Fosi Audio products. They are excellent quality and last a long time. The tube pre-amp and two channel amp have been in service since 2016!

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.

Nutze den Verstärker für 2 Bass-Shaker von Reckhorn im Parallelbetrib (4 Ohem). Funktioniert gut und die Leistung ist mehr als ausreichend.

Acheté pour amplifier le son de mon ancien mais bon actif subwoofer d’une vieille radio que je comptais jeter , suis tres content du résultat.

Ok i have now had my unit for almost 3 years powering a buttkicker mini in my sim rig and i really cant put it over a third as it rattles the whole rig with zero problems have a m04 too and that doesnt even compare probably getting another of these to replace the m04 highly recomended although i would not really get it for anything that needs more than 100w rms @ 4ohm i havent tried it with 2 ohm but it would raise distortion and wont get more than 108w from the power supply anyways so yeah 100w 4 ohm load perfect

This little ripper replaced a home-built subwoofer theatre amplifier that kept our movies “thumping” for over 20 years. It weighed about 4 kg with a massive torroid coil transformer feeding the amplifier push-pull circuit. No matter what hubby did, he could not get rid of the low frequency hum when no input signal was coming in from the Yamaha theatre receiver sub output. Apart from that, it thumped the passive subwoofer speaker for two decades. We decided we needed a replacement for “old hummer”and chose this unit. It arrived and I was a little taken aback - it is 1/4 the size of the previous amp. I wasn’t sure what to expect. Needless to say, I need not have worried. This little unit packs a massive punch into the 8 inch, 6 Ohm subwoofer speaker and when there is no input, it is as quiet as a church mouse. Bye bye humming... We have to have the FOSI set at about 1/3 to 1/2 volume otherwise the sub overpowers the rest of the theatre sound and starts rattling our French doors leading into the theatre room. I get that it is new and you can never be assured of the longevity, but the quality from the outside looks and feels good and the output at a low volume setting is simply amazing - despite its miniature size. Clear and concise. And no idle hum. :-) Long may it stay this way!
