Can you fit an amp to the standard 147 headunit?!
The Bose configuration isn't quite the same. Jomor did manage to mod a headunit to give RCA outputsYes, there's an option on the alfa radio to convert the speaker outputs to high-level RCA outputs ( as used in the Bose configuration )
conventionally, to send the audio signal to an outboard amplifier, you use RCA audio cables. this setup works via the so-called 'low level' audio signal; that is, 'low voltage' (typically <4V). it is low level because the signal does not pass through any amplifier inside the headunit.all very confusing
