W208 third connector with AMP on it in stereo HU
title may sound little frustrating, but ill try my best to explain
ive got factory BOSE AMP and stereo in my W208(not convertible if it matters in this case)
thing is, Stereo HU is aftermaket JVC, and from HU place there comes three connectors , two of them are already connected in jvc, but third one, which is thinner and bigger with amp on it, is not connected.
can someone tell exactly what it is for? from videos and threads ive searched, its either for BOSE AMP and in my case its not connected in HU, or its for multiwheel which somehow my '01 car does not have
ill appreciate any info
thanks!
