Look through the wiring diagram to see what components need to be connected to what prior to soldering. This is a modification of my LM386 instructable (http://www.instructables.com/id/LM386-Audio-Amplifier/).
This is one of two portable speaker systems i wanted to build. I used the LM386 circuit from my previous instructable and incorporated it into this portable speaker system. It is a single channel (mono) speaker system which lights up blue in the background when you turn it on. I hope you enjoy this one and feel free to give me suggestions or ask me to clarify anything that may be confusing.
