I salvaged a pair of speaker drivers from USB-powered computer speakers that is .75 Watts/8 ohm per channel (2 channels total, L/R). I want to be able to drive audio through it and have volume control. I know that a basic audio system requires:
- Signal source (For simplicity, I want my device to take the signal via AUX port)
- Power amplifier
- Speaker driver
With such a low RMS power rating, I'm tempted to connect the L/R channels from a source directly to the speakers but I'm not sure of the energy of the source signal.
