U need 200w rms 6 ohm speaker to exceed amps capabilities. These run bookshelf speakers all day!!
Reviewed in Canada on June 12, 2025
Verified Purchase

Wanted better sound while camping and watching superhero movies... (they hit harder with full sound...) and the fosi came up huge! If youre in an rv or solar set up like us... the bluetti only draws 15w from the power station. Even turned up loud... 15w. Our 80w rms bookshelf speakers seem to be pushed hard with this little amp. We have a yamaha rx v4a at home that sounds just as good. Obviously the yamaha amp is louder and fuller with more detail... but it's also 5x the price. This will rock a party, and be louder than you need it to be we have fussy 6 ohm speakers and they are pumpin!

Good product but lack of power for my room
Reviewed in Canada on June 6, 2025

Sound was great but not enough power to drive my totem speaker in my leaving room. possibly a too large room. They say 2x165W but it certainly not delivering this. I'll possibly switch to the BT20A Pro and see if the 2x300 bring that extra power needed.

Great upgrade to the Klipsch promedia 2.1 internal amp.
Reviewed in Canada on April 26, 2025
Verified Purchase
My Klipch promedia 2.1 v1 amp in my active sub was getting old enough to be a worry(22 yrs). Since I was replacing my blown subwoofer, I decided to go with an external amp while I was in there. The 32 v 5 amp power supply is enough power to replicate the volume output of the original amp. Note I run the fosi over 1/2 volume to match about 1/3 the Klipsch internal amp volume. The fosi amp is much cleaner sound wise than the 22 yr old Klipch. No hum from the speakers when the fosi is turned on. I think the fosi is an upgrade to the internal Klipsch amp. Less powerful than Klipsch, but can still put out the same volume I’m use to (fairly loud per the wife). In my opinion, this amp will easily power a small 2.1 system like the promedia 2.1 I have. Fosi does have a 30 pro amp that can take a 48v power supply and produce much more watts for a bigger system( bigger bucks of course).

j etais septique avant l achat mais apres avoir branché les hp , wow vraiment ��ǲԲ�é par le son , surement pas le wattage annoncé puisque le transfo fournit ne peut pas delivrer la puissance indiqué mais suffisant pour une ecoute domestique a tres bon volume. le seul hic est que l ajustement de la frequence de coupure du sub est aleatoire .
dans l ensemble tres bon achat et la reception du Bluetooth est tres rapide. reste a tester la durabilité du produit qui est souvent la faille des produits made in china .

Not bad for the price, it’s not as loud as I thought it would be but still pretty good. This would be perfect for a home theatre, just a little under powered to listen to music for me, but I like it really loud, again still decent. The sound quality is pretty good all in all it’s worth the money.
