Hello, I have to buy a DSP from Mosconi and connect to an OEM radio. Without going into details, I would like to know, if I use the PlugIn adapter, can I theoretically use the original LS cables or do I have to relocate them all? From the quad block 4 LS cables go out, but there are original 5 LS installed (each in the doors, 2 tweeters in the dashboard and another center also in the AB. All LS do nothing and must of course I have not found a switch, but I do not know how to branch off the sygnale for the tweeters and the center. It is a MB Sprinter of the current series.
