Unfortunately I can not understand the previous negative reviews. The adapter was delivered quickly and had a comprehensive description. So I took my time over the weekend and installed the adapter. Quick postponed the core insulation, soldering set, isolated. And already sat the adapter parallel to the radio outputs and inputs. Continuous voltage, ground, left speaker + and -, + and right speakers -
The remote is working properly. The level is more than adequate. For 20 Euro really an unbeatable price. Anyone who wants to operate a subwoofer at the original radio, is operated really well with this adapter.
