Today I'm testing out a mini home amplifier from Fosi Audio. This amp is a top seller on Amazon and at the time of this video cost less than $80. It's a bit confusing what the power ratings are, however, as in some places it's listed as "300W", others "200W Max" and finally 150W RMS. Which one is correct? Are any correct?
The Fosi Audio M0-3 incorporates the Texas Instruments TPA3255D2 chip and requires between 24-35VDC of input for power. The included 32V 5A adapter may not allow the max power output, according to the text on Amazon. With this being true, I tested the amp using the included AC/DC adapter, then also purchased a larger power supply to see if the amp would do more power given more voltage and additional current. Find out if this purchase was worth the extra $40 or not....spoiler, it wasn't!
Features of the Fosi Audio M0-3:
Full Range (PBTL) or Subwoofer (Sub) Output
Variable Subwoofer Frequency Control
RCA Line Level Output for Powered Subwoofers
Banana Plug Jacks for Speaker Outputs
Aluminum Enclosure
Since the lowest power shown for the amp is 150W at 4 ohms and 120W at 8 ohms, these are the numbers we'll reach for. Let's find out if it can perform as advertised...
