Hello Leutz, I need your help again and I promise a lot from you this time! I have the following problem, and I have a Magnat bass box and a Blaupunkt amplifier. (See photos). Until then nothing exciting! I would like to get this in my little one, however, from the place no topic but with my technical understanding it slurps a little. Can you tell me what else I have to get for cables so that everything fits so well and which cable then I would like to do it myself so that I know what goes on when problems occur or I don’t want to pay for the installation! Abpropo: What would the installation cost with everything around it or what is my stuff still worth as much as on the pictures? For a couple I would be very grateful… Best regards
