Speakers were not working

I have this cable as an alternative to cable what my Alpine CDE-W296BT came with brought because it was shorter and thus easier to block. It worked first seemingly everything, until I realized these were the front right and rear left loudspeaker without function. The original cable what I had installed, however, everything worked flawlessly.

Now speculation from me is that it was not working properly because the contact shoes that go in in the plug to the radio, are quite high up and could have probably touched by the contact of the adjacent cable, so that it came to a short circuit. At least, my impression when I had a look at the cable times closer. The original cable is as much more workable. Here the contacts stuck deep in the plug, so that's ruled out contact with the neighboring cable. From the cable assignment of this cable was the original cable way, identical, so that can be ruled out a malfunction of this page.

I'm really endtäuscht it probably much inferior stuff on the market of cable and adapter, and you probably have to look exactly what you are buying there. Actually a Rätzel that you can do something wrong on something simple, and you do not hinbekommt something sensible manufacture of cables and connectors.
