I want to wire my comps up to my amp, so the wires need to be fed into the door, I don't want to connect them up to the ISO connector anymore as I tried once before and I made a bit of a mess of that, also the wires are totally different sizes so it's awkward to connect them, and also again I don't want to have to take my head unit out again, the way some of my wires are routed I'd have to unplug them to get it out lol. Anyway, point is, is it simple enough to use the existing door wiring loom to pass my speaker wires through into the door? (I mean the rubber tube thing in amongst the door hinges.) As far as I have gathered there are connectors on each end with loads of holes, some are used and some are not. I thought surely I could make a bigger hole where there are no wires in the connector and pass my wires through that way? Main thing though is how do I unplug it so I can see the pins? Just pull it off or does it need to be twisted?

Ideally I'd want to leave the standard car wiring as it is, but connecting to the wires behind the head unit (ISO connector) is still an option. I assume it's the same colours for the wires to the speakers on that?

yeah its the same wire throughout.

i guess you could multi meter to find the dead pins (if you get me) im not to how on corsa b electronics.

you just twist the end 1/4 turn and it comes off. was very stiff on mine.

worst case.. drill into the door nd thread the wires through... this is what i did, i didnt trust vxl cables with 175 wrms lol

Well in the connector block there are a number of holes (apparently), some are used for pins to make connections but some are just empty holes. I thought surely I could drill a hole where there are no pins and pass wire directly through the connector block? Just need to know how to unplug it from the door. So you reckon turn then pull?
