VW Golf 6 Car Hifi (speaker)

Hey guys, I’m new to the forum and in general also new to the Car Hifi area, I hope the topic belongs here. So to my location, I connected last year in April a subwoofer (Gladen RS 12-VB Allround) with appropriate power amplifier (Gladen RS 100c4) after hard and long 2 days. Now I would like to replace my speakers in the front doors with the Gladen ONE 165 Golf 6-SQX or Gladen ONE 165 Golf 6-RS (don’t know yet ) I have some difficulties yet. I would like to wire the speakers to the power amplifier, that would have to work so that I put the loudspeaker cables forward to the radio and cut the cables from the ISO connector (logically not from the original but from the connection for the radio) and connect them to the squeegee connectors. As in this video -> https://www.youtube.com/watch?v=B26Z-HS9YNk (from approx. minute 36:00) I have to put a cable for the tweeters, my it doesn’t know, because that’s a plug&play set of Gladen and they are connected to the tweeter. (Please click on ) Oh yes, Radio is a Pumpkin Android 8.0 (I know many don’t like it, but I’m really excited about it) and the power amplifier is placed in the trunk. I have 2 pictures attached to the plug (with the radio coming 2, one is installed with the canbus in my car and the 2nd is this), to my knowledge it would be there nn the right chamber with the lilans, grays etc. cables that need to be cut through or? I hope I could explain my problem a bit and explain it intelligibly. xD Sincerely Kenny
