Hello A3 municipality. After I ordered my A3 and picked it up in Ingolstadt, my cousin also ordered an A3 (1.9TDI) and it was delivered the day before yesterday. Unfortunately, the good ones forgot to order a radio, really simple and easy. Women!!! 🙂 Every frills ordered but the radio did not. Actually it should have been like in my 8P the concert, with 8 loudspeakers. She was of course slightly shocked and asked me also e Since many of you are quite knowledgeable, this was of course close to posting in this forum. Basic assumptions are: – There are no cables for the audio system, – foreign manufacturers are leaving, – the system must be the original Audi system. Now to your questions: 1. Is it possible to retrofit the concert with loud speech including the woofer and the center box? Reasonable solution. 2. Has this perhaps been done by any of you? 3. With what kind of food? An Audi employee said that could be quite difficult, because the Can-Bus networking seems to be complicated. 4. What would the pure wiring cost, i.e. without radio (possibly reference to 3rd person) and without boxes 5. How long will the installation take cirka? (Complete system) Is it to be expected that everything then clatters and pinches, because the workshop has to dismantle the interior cladding and the reassembly is not quite possible? structural contributions that lead to a solution are my cousin and I, of course, also very grateful.
