[morelia21a]

Hi!!

I was wondering if any of you have came up with this issue...

i wanted to install some rear speakes in my 6j 2016 but when i took apart the panel i found that i have some speakers wires aready.. so i take off the stereo to see if they were connected and no.. so i just hace 2 front spearkes connected to my stereo and 2 rear spaces with cables for some other speakers.. so any of you knows what are tese cables doing? or where are they going?

i tested and they have no continuity. the have 0 voltaje.. it appears they are just existing lol
