Soldering went well. Anyways I I pulled the headunit out again and now the right rear is still working but very soft so that means my rear left speaker is the only working one now... i think its due to the wires bending when I put the head unit back in?
OH SHIT!!!! Had a fiddle around with the wires and all the speakers were working perfectly then I put it back in the car and then put back the negative battery in then the lights in my car wern't working!!! Only the dashlights work now. The head unit and other interior lighting are not working!!!!!!! I've checked the head unit fuse and it's now blown! Maybe I knocked out a power harness or something???
My mate took a look and found the blown fuse. Replaced it and now the interior lights and head unit works. The central locking still doesn't work though and I noticed a missing 30 A fuse.....
glad that helped solve some problems, but now for all the things that are still not working look for those fuses, keep in mind that some cars have two fuse boxes one under the hood and one usually by the driver side dash
