Review on DROK Super Small 3W+3W DC 5V Audio Amplifier 🔊 Module Board Dual-Channel PAM8403 Stereo Amplifiers for DIY Portable with Potentiometer by Rain Flores

The aim was to boost the Blackberry Bluetooth adapter connected to the cassette adapter so that I can stream from the iPhone. Blackberry is USB powered and was pretty weak. I have to turn the volume up a bit, so I hear this hiss. This amp is inexpensive and works. Perhaps because I used all the wires I could find to solder together, this DROK hisses too. Tried with headphones and forgot. A noise filter is a must. It's hard to complain about the price, though, and it's improved really well. I have yet to try some passive speakers but I think this unit is the best for it. I only used it for about 4 hours and decided to forgo the entire setup and got myself a Logitech bluetooth adapter and truck inverter to make it work. This device is much better than BlackBerry.
