Review on 🔊 AIYIMA 100W Subwoofer Amplifier: HiFi Mono Channel, Full-Frequency & Sub Bass Switchable Stereo Amplifier for Home Theaters – Silver by Juanita Valentin

I bought a bluetooth, LED light, karaoke speaker on sale (proof of a reset?) because of the excellent bass response and a month later it squeaked and died. The cabinet really shook, so I bought this little amp, cut open the speaker's plastic cabinet and removed the dead guts to install this powerful unit. I don't use a BASS crossover on the woofer, I use it over the full frequency range and play with it outside. Clearly reproduces rock guitars, drum machines, OC-3 bass frequencies and vocal harmonies. Gets louder with some preamp; I use a small portable stereo recorder directly in front of the amp as a volume control, but I can also access the amp knob in a pinch.
