Have a good evening light, have a problem, vllt. can give me tips or help me. And this is about the following, have a high-low adapter for the Cinch outputs, remote I got on the antenna amplifier and mass as usual in every car under the belt fixtures and 12V from the distribution box, you call it so?!?! ALso that was already there already with the Golf IV and with my E39 is now also the case, that there is a socket, where all cables of components the current br so let’s say 5 things need electricity, and then there’s a big cable direction battery + but I think you know what I mean Well, all funzt still great, all lautsprecher etc… only the power stage and of course the subwoofer don’t want to jump on then Where could the error lie, have really no plan. Thanks for every tip and advice greeting Ricky
