Hello people. I’m sorry that I opened up a new topic again. I just didn’t find the right answer in the existing one. my colleague has a V40 T4 year 2001 with original subwoofer back right. I think he’s passive. my colleague doesn’t know electrics so well, I have a golf 3 myself, but know me well with electrics (professional electronics). we want to install a blue-point active subwoofer in the suitcase room. now the question: where can I pick up the sound signal for the subwoofer? simply with the original in the side wall? where do I get the remote signal for the subwoofer? current cable is clear to me, from battery in the interior to the rear. the original radio (volvo radio with cd and cassette) we want to keep on every case. as I said, I come from the VW Golf 3 world and therefore don’t know me so much. I hope that someone can explain it friendlyly.
