I've got the H6147 RGBIC (2x10m) LED strips and the length between the built in controller box and where the strips start is just way too short (image #1). There ought to be a way to extend this cable and make it longer.

Here are my ideas:

Idea #1, image #2 - is there a way to somehow take apart this little connector between the strips and the control box and add an extension cable there?

Idea #2, image #3 - There's a seam that starts at the bottom of the controller box (where the two cables are connected to it) that goes all the way around to the top of it on the back part. Might there be a way to open the controller box itself, take out the two connected cables, connect them to an extension cable and then connect the other side of the extension cable back to the control box?

I'd highly appreciate if someone could tell me what's possible and give me any more ideas on how to extend the cable between the controller box and where the LED strips, and move the controller box further away from the LED strips themselves. It'll be a huge help.

Thank you!
