Recently I became the owner of a 57 octavia estate, I'm very happy with the car although noticed the rear door speakers are missing. I would appreciate some advice on removing the door card and the size of speakers to use. Any step by step info would be great as I can't get the door panels to shift , thanks

Not tried it myself, but try the link above!

Thanks very much Andehh, very helpful link, i got as far as taking out the screws, but the darn panel wouldnt budge so i guess i should get some of them green clips from Skoda then give the panel more welly and hope for the best

Old thread I know - but I finally got around to fitting rear speakers in my Octy II 1.6 bog standard model: sick of the kids complaining they couldn't hear in the back while I was haemorrhaging  from the ear. 

 

Anyway just in case someone fancies putting some in I thought I'd give a little bit of info. There is no wiring for speakers going into the rear doors - the wiring that is there is for the central locking. 

 

Basically I spliced into the wires that were going into the front speakers. So to keep it simple I found the cable coming out of the stereo going to the front drivers door - I spliced into it a cable to feed the rear  speaker. ( I used FLI Audio Integrator 6 6.5" inch 165mm 3-Way Triaxial 210 Watts Car Door Coaxial Speakers Set, purchased from Amazon for £27). 

 

I traced where the speaker cable was by pulling the rubber grommet/cable carrier that goes between the body of the car and the door (when you open the door you can see the hinges and the rubber cable carrier), it unclips if you pull it. I then found where the cables where going into the carrier from inside the car - basically I identified the right loom carrying the speaker cables. 

 

On the passenger side I pulled the side of the dash (the same type of panel as you pull to get at the fuse box) and got a good look and was able to pull at the loom a bit - I also undid a fair bit of the black binding that was around the loom so I could get at the speaker cables more easily. Now this is the important bit: for the passenger side the positive speaker cable is blue and white at the loom inside the car (although it is red inside the rubber cable carrier going to car door), the negative cable is brown and white at the loom inside the car (it is brown and red inside the rubber cable carrier going into the door. I spliced into the loom inside the car leading a cable under the trim at the bottom of the doorway and up through the trim where the seatbelt is housed, and out through the rubber cable carrier to the rear door and installed the speakers - if you do get the same speakers you will need M6 sized bolts x 8 (4 for each door), they were not included with the speakers, unless I lost them...I followed guides on here on how to remove the door cards. 

 

On the drivers side I had to take off  the underside of the dash under the steering wheel,  which sounds worse than it is (and the trim along the bottom of the doorway) to see where the speaker cables were going into the door - I wanted to be sure that the cables in the loom that I thought were the speaker cables were definitely leading to the speaker connections in the door. The cables in the loom inside the car were positive red (though blue and white in the rubber cable carrier) and negative inside was red and brown (brown and white in the rubber cable carrier). 

 

So a rough way of doing it. The trims were a bit of a pain in the ar5e. However, it works, kids are happy and for less than £30 a rewarding job for a decent sunny day. Obviously the only balance is left and right not forward and rear. There might be a more elegant way of doing the same thing but I couldn't find anything. 

 

If my info is not clear I apologise, I advise you go and buy a haynes manual which will show the audio wiring diagram, giving the colours and then start removing trims and tracing wires as I did - it will take less than a day and is a significant upgrade IMO for those of us cheap enough to get the base model and who have teenagers who keep saying 'turn it up'. 

how did you find getting 6.5" speakers to fit? OEM are 5.25" and trying to get my 6.5" mids to fit was a knightmare

I suspect the car has a Stream or Stream MP3 head unit?

May not be right but I have a feeling these head units have 4 channel amps....if you connect something to the rear channels they activate (you then get the fader option) and dont think it needs coding (may do though). Bit of wiring and you'd have an OEMish rear speaker set up.

Only thing of concern is that you are now running two additional speakers off of the existing 20w x 2 front channels....turn it up too much you'll end up overworking the amp/causing clipping and may shorten the amplifiers life. Just dont be overly surprised if your head unit goes pop at some point.

Just checked in, sorry to Ryan for not responding - luckily I din't have any problem fitting? 

 

 

Anyway, just about a year later, and the stereo and speakers are going fine, for anyone who wants to try my method of splicing in. 

 

Though would be better to wire in to the four channels if possible as suggested by Pipsyp.
