Review on 🔊 Gikfun 3W Full Range Audio Speaker Stereo Woofer: Arduino Compatible (2pcs) by Fred Boals

I soldered 20 gauge wire and attached Dupont pins to each speaker. They worked perfectly with DFPlayer and MP3 Player TF card U drive. None of the players were able to push them in levels of distortion. They withstood the volume up to the power limit of the breadboard power supply (the type that snaps onto the top and bottom rails of the breadboard). The DFPlayer and MP3 Player amplifiers require more power than this power supply can supply. But there are no problems with speakers.
