Hello guys! This is my first post on Sparkfun! I want to make a project. My purpose is adding bluetooth mode to a standard car tape using BK8000L module via aux-in. I looked for some projects and they all used 3W amplifiers for this. (They made DIY bluetooth speakers) But what I think is they used the amplifier for the speakers. I want to use 3.5 mm socket for speakers output and transfer the sound to the car’s aux-in using aux cord. Is this possible? Do I still have to use amplifiers? Thanks!
