Hi guys - would appreciate help greatly! Am looking at putting in some 6X9s into the rear of my 2008 Ibiza. Got the acoustic parcel shelf, 6X9s, all I need to do is sort the wiring. Under the rear passenger bench I can see a cable going off to the left, and one off to the right, near where the rear speakers are. Both cables say OP 2914, and have FLR31Y11Y stamped on them (wire manufacture I think). So, is it OK for me to cut both these cables and divert to the new rear speakers? Worried that I'm going to cut the rear lights or something!!!
