stressed.
No need to panic ;-)

Ok, if you can't trace where they go, you will need to do a listening test.

You know the thin wire goes to the doors. So, Cut one spice only, so you have three cables. Bind the thin cable with one thick cable, turn on the stereo and see if anything comes out the doors. If it does then the thick cable you bound to the door cable is the feed from the Head Unit. If there is no sound from the door speaker, then you have identified the feed to the sub.

Repeat with the other pair/splice (having spliced the first three back as one temporarily) to identify the feed from the head unit for the other cable splice.

Repeat for the other side! I just hand bound them back together and used a bit of insulating tape to hold the connection and stop it shorting.

Rich.
