Hi guys, I have a Volvo C30 and there it doesn’t make sense to exchange the standard radio because the air conditioning system is running on the radio My question: I bought an active subwoofer this of course has 2 Cinch inputs my radio has no Cinch output. So I have to come from Cinch to my normal speakers or on the cable of it. Sure I lose quality but I know that I can tell myself who I have to put the cable ? if I cut the Cinch cable I have a total of 4 cables two of the white and two of the red. And a speaker cable has only two poles. Which cable is about ? how do they have to come together ? thank you already
