Amazon's Best Seller - Amp Dyno of the Fosi Audio TP-02 Subwoofer Home Audio Amplifier

Today we tested a mini home subwoofer amplifier from Fosi Audio. This amp was to replace a 300 watt BASH plate amplifier that died for my CNC’ed subwoofer utilizing an Image Dynamics IDQ12 in a ported enclosure.

This amp is a top seller on Amazon and at the time of this video was priced less than $70. The amplifier states it will do 220 Watts MAX output which is usually a bad sign. The instruction manual states that it won't really do that power output in a snippet. It's a bit confusing what the power ratings are. What is the true power output?
The Fosi Audio TP-02 incorporates the Texas Instruments TDA7498E chip and NE5532 operational amplifier for excellent sound quality. The amplifier includes a 24V 4.5A adapter, based on the math alone 220 watts isn’t possible.
We tested the amp using the included AC/DC adapter at 2 ohms and 4 ohms, then measured frequency response, we also did some audio playback tests so you can see the amplifier in action.
You can now use you car audio subwoofer in your home!
Features of the Fosi Audio TP-02 amplifier:
Limited frequency response for subwoofer use
Variable Low Pass Subwoofer Frequency Control
RCA Line Level Output for Powered Subwoofers
Banana Plug Jacks for Speaker Outputs
Aluminum Enclosure
Excellent feel potentiometers

does the crossover from sub frequency knob apply on sub out as well as on speaker terminals out? I would like to use it as active crossover.
my passive sub is connected on amplifier that doesn't have crossover so I would used this fosi sub out so I can control frequency with it. but I need to be sure that the sub frequency control from Fosi applies on sub output on Fosi.
thanks

PA amplifier such as t.amp E-1500. You can power good subs such as VXF series comfortably @ bridged

[@skillcandylive]

hilariously this popped up after I just got a set of subs today and I wasn't sure what to do with them lol now I do awesome 😎 🙌

[@Qualitymobilevideo]

Lol niiiice 👌😎

[@fritschomat5996]

Hello, thank you for the interesting video. I would like to have a question answered. How much power does the little Fosi use when there is no signal? Many thanks

[@fredrikastrom9372]

NOT a pipe dream. Amps have capacitors and music is dynamic, so it can unload more than volt*ampere for when it counts. Plus you can upgrade the power supply to get more power.

[@carlomispa9730]

Thanks for this review! :) I have a question, does it have holes in the bottom, to fix it?

[@Qualitymobilevideo]

No it does not.

Hey im getting a Rockford Fosgate P1-2X12 Punch Dual P1 12" Loaded Enclosure. Which amplifier should i get with it ?

[@calebguynn7124]

I have 2 12" subs with a rms of 1,200 each making it 2,400 total rms and the 20% would be 2,880 amp is what I need but those amps cost about 500$ to run 2ohms at 2,900 am I doing something wrong or is there something I'm missing. Bc I want this for my car and a 500$ amp seems like too much and then I would need a new alternator for my car bc of the power I would be drawing.

Can this amp to Push the subwoofer Rockford Fosgate P2 8” (250RMS) ?

[@Qualitymobilevideo]

yes

[@traildoggy]

Is this thing quiet when idle or is there any noticeable hum at low volumes? I have a cheap powered sub that has a nasty 60 cycle hum that I can't eliminate and I'm thinking of just converting it to a passive speaker or replacing w a car sub.
