Thanks for the call earlier Patryk. Can you confirm this cable would work in the 5m length?

If not, I'll call them direct to see if this works. You mentioned it had to double loop so hopefully this is built into the harness.
On another note, you also mentioned retrofitting a centre speaker to my car. That would involve cutting the dash to get it fitted but I'm very concerned about screwing that up! Has anyone tried this on a base stereo car?
